Search Worlds Without End

Entered by a thousand unsuspected gateways -- built by a race lost in the clouds of time -- the planet its dwellers called the Well World turned beings of every kind into something else. There spacefarer Nathan Brazil found himself companioned by a batman, an amorous female centaur and a mermaid -- all once as human as he.

Yet Nathan Brazil's metamorphosis was more terrifying than any of those...and his memory was coming back, bringing with it the secret of the Well World.

For at the heart of the bizarre planet lay the goal of every being that had ever lived -- and Nathan Brazil and his comrades were...lucky?...enough to find it!

Hugo Award nominated novelette. It originally appeared in Isaac Asimov's Science Fiction Magazine, August 1991. The story can also be found in the anthologies Supermen: Tales of the Posthuman Future (2002), edited by Gardner Dozois and The Hard SF Renaissance (2002), edited by David G. Hartwell and Kathryn Cramer. It is included in the collection Stories of Your Life and Others (2002).

Stories of Your Life and Others presents characters who must confront sudden change--the inevitable rise of automatons or the appearance of aliens--while striving to maintain some sense of normalcy. In the amazing and much-lauded title story, a grieving mother copes with divorce and the death of her daughter by drawing on her knowledge of alien languages and non-linear memory recollection. A clever pastiche of news reports and interviews chronicles a college's initiative to "turn off" the human ability to recognize beauty in "Liking What You See: A Documentary." With sharp intelligence and humor, Chiang examines what it means to be alive in a world marked by uncertainty and constant change, and also by beauty and wonder.

The collection received the Locus Award and the stories have received the Hugo, Seiun, Nebula, and Sturgeon Awards.

Hugo-nominated Novella

In novels such as Chasm City and Revelation Space, Alastair Reynolds established himself as an indisputable master of the far-flung intergalactic epic. Reynolds brings that same deceptively effortless mastery to the shorter fictional forms, a fact that Troika, his elegant, compulsively readable new novella, amply demonstrates.

Troika tells the story of men and women confronting an enigma known as the Matryoshka, a vast alien construct whose periodic appearances have generated terror, wonder, and endless debate. During its third "apparition" in a remote corner of the galaxy, a trio of Russian cosmonauts approach this enigma and attempt to penetrate its mysteries. What they discover--and what they endure in the process--forms the centerpiece of an enthralling, constantly surprising narrative.

Troika is at once a wholly original account of First Contact and a meditation on time, history, and the essentially fluid nature of identity itself. Suspenseful, erudite, and gracefully written, it is a significant accomplishment in its own right and a welcome addition to a remarkable body of work.

These 18 darkly complex short stories and novellas touch upon human nature and perception, metaphysics and epistemology, and gender and sexuality, foreshadowing a world in which biological tendencies bring about the downfall of humankind. The Nebula Award-winning short story "Love Is the Plan, the Plan Is Death," the Hugo Award-winning novella "The Girl Who Was Plugged In," and the Hugo and Nebula Award-winning novella "Houston, Houston, Do You Read?" are included.

Private William Mandella is a hero in spite of himself -- a reluctant conscript drafted into an elite military unit, and propelled through space and time to fight in a distant thousand-year conflict. He never wanted to go to war, but the leaders on Earth have drawn a line in the interstellar sand -- despite the fact that their fierce alien enemy is unknowable, unconquerable, and very far away. So Mandella will perform his duties without rancor and even rise up through the military's ranks... if he survives. But the true test of his mettle will come when he returns to Earth. Because of the time dilation caused by space travel the loyal soldier is aging months, while his home planet is aging centuries -- and the difference will prove the saying: you never can go home....

A secluded Pacific Northwest cottage becomes a door to the past for Tom Winter, who travels back to the New York City of 1962, followed by a human killing machine that he alone must stop.

The fourth and final volume of The Saga of Pliocene Exile.

Until the arrival of Aiken Drum, the 100,000 humans who had fled backward in time to Pliocene exile on Earth knew little but slavery to the Tanu -- the humanoid aliens who came from another galaxy. But King Aiken's rule is precarious, for the Tanu's twisted bretheren are secretly maneuvering to bring about his downfall. Worse -- Aiken is about to confront a man of incredibly powerful Talents who nearly overthrew a galactic rule. He is Marc Remillard. Call him . . . The Adversary.

Slaughterhous-Five is one of the world's great anti-war books. Centering on the infamous fire-bombing of Dresden, Billy Pilgrim's odyssey through time reflects the mythic journey of our own fractured lives as we search for meaning in what we are afraid to know.

Unstuck in time, Billy Pilgrim, Vonnegut´s shattered survivor of the Dresden bombing, relives his life over and over again under the gaze of aliens; he comes at last to some understanding of the human comedy.

For twelve thousand years the Galactic Empire has ruled supreme. Now it is dying. But only Hari Sheldon, creator of the revolutionary science of psychohistory, can see into the future--to a dark age of ignorance, barbarism, and warfare that will last thirty thousand years. To preserve knowledge and save mankind, Seldon gathers the best minds in the Empire--both scientists and scholars--and brings them to a bleak planet at the edge of the Galaxy to serve as a beacon of hope for a fututre generations. He calls his sanctuary the Foundation.

But soon the fledgling Foundation finds itself at the mercy of corrupt warlords rising in the wake of the receding Empire. Mankind's last best hope is faced with an agonizing choice: submit to the barbarians and be overrun--or fight them and be destroyed.

Three strikingly different alien races greeted the military mission from Earth when it reached the planet called Bezer'ej.

Now one of the sentient species has been exterminated -- and two others are poised on the brink of war.

The fragile bezeri are no more, due to the ignorant, desperate actions of human interlopers. The powerful wess'har protectors have failed in their sworn obligation to the destroyed native population -- and the outrage must be redressed.

But those who are coming to judge from the World Before -- the home planet, now distant and alien to the wess'har, whose ancestors left there generations ago -- will not restrict their justice to the individual humans responsible for the slaughter. Earth itself must answer for the genocide. And its ultimate fate may depend on a dead woman: former police officer Shan Frankland, who became something far greater than human before destroying herself in the vast airless depths of space.

This collection from Grand Master Robert A. Heinlein includes five short stories sure to please science fiction fans everywhere.

All You Zombies -: A young man walks into a bar and meets a time-traveling bartender whose origins - and relation to the young man - are more convoluted and stranger than the snake-swallowing-his-tail ring on the barkeep's finger. This is considered one of the most influential and thought-provoking short stories ever to tackle the mind-bending nature and paradoxes of time travel.

The title story was adapted into the theatrical film Predestination in 2014.

One of Isaac Asimov's SF masterpieces, this stand-alone novel is a monument of the flowering of SF in the twentieth century. It is widely regarded as Asimov's single best SF novel.

Andrew Harlan is an Eternal, a member of the elite of the future. One of the few who live in Eternity, a location outside of place and time, Harlan's job is to create carefully controlled and enacted Reality Changes. These Changes are small, exactingly calculated shifts in the course of history, made for the benefit of humankind. Though each Change has been made for the greater good, there are also always costs.

During one of his assignments, Harlan meets and falls in love with Noÿs Lambent, a woman who lives in real time and space. Then Harlan learns that Noÿs will cease to exist after the next Change, and he risks everything to sneak her into Eternity.

Unfortunately, they are caught. Harlan's punishment? His next assignment: Kill the woman he loves before the paradox they have created results in the destruction of Eternity.

Exiled beyond the time-portal into the world of six million years ago, the misfits of the 22nd century are enmeshed in the age-old war of two alien races. In this strange world, each year brings the ritual combat between the Firvulag and the Tanu.

Before becoming one of today's most intriguing and innovative mystery writers, Kate Wilhelm was a leading writer of science fiction, acclaimed for classics like The Infinity Box and The Clewiston Test.

Now one of her most famous novels returns to print, the spellbinding story of an isolated post-holocaust community determined to preserve itself, through a perilous experiment in cloning. Sweeping, dramatic, rich with humanity, and rigorous in its science, Where Later the Sweet Birds Sang is widely regarded as a high point of both humanistic and "hard" SF, and won SF's Hugo Award and Locus Award on its first publication. It is as compelling today as it was then.

In the far future, the Heliothane Dominion is triumphant in the solar system, after a bitter war with their Umbrathane progenitors. But some of the Umbrathane have escaped into the distant past, where they can position themselves to wreak havoc across time and undo their defeat. The most fanatical of them is the superhuman Cowl, more monstrous than any of the creatures outside his prehistoric redoubt.

Cowl sends his terrifying hyperdimensional pet, the torbeast, hunting through all the timelines for human specimens. It sheds its scales -- each one an organic time machine -- where its master orders. Anyone who picks one up is dragged back to the dawn of time, where Cowl awaits. Then the beast can feed, growing ever larger . . .

In our own near-future, Tack is one of U-gov's programmable killers. When a scale latches onto him, his doom seems inevitable, but the Heliothane have other ideas: they can use Tack against Cowl. Tack is no stranger to violence, but the Heliothane, hardened in their struggle for humanity's very existence, have much to teach him. He will need it all for his encounter with Cowl.

Once one of Tack's targets, Polly escaped with her life when a torbeast scale snatched her. Now, like Tack, she must learn fast as she is dragged back to Day Zero. To cheat death again, she will have to help him save the human race.

With Cowl, Neal Asher, acclaimed author of Gridlinked and The Skinner, has created his most powerful novel yet.

Ray Bradbury is a modern cultural treasure. His disarming simplicity of style underlies a towering body of work unmatched in metaphorical power by any other American storyteller. And here, presented in a new trade edition, are thirty-two of his most famous tales--prime examples of the poignant and mysterious poetry which Bradbury uniquely uncovers in the depths of the human soul, the otherwordly portraits of outré fascination which spring from the canvas of one of the century's great men of imagination.

From a lonely coastal lighthouse to a sixty-million-year-old safary, from the pouring rain of Venus to the ominous silence of a murder scene, Ray Bradbury is our sure-handed guide not only to surprising and outrageous manifestations of the future, but also to the wonders of the present that we could never have imagined on our own.

In the year 2301, guns are only museum pieces and benign telepaths sweep the minds of the populace to detect crimes before they happen. In 2301 murder is virtually impossible, but one man is about to change that...

Ben Reich, a psychopathic business magnate, has devised the ultimate scheme to eliminate the competition and destroy the order of his society. The Demolished Man is a masterpiece of imaginative suspense, set in a superbly imagined world in which everything has changed except the ancient instinct for murder.

At last, the costly and bitter war between the two Foundations had come to an end. The scientists of the First Foundation had proved victorious; and now they retum to Hari Seldon's long-established plan to build a new Empire that the Second Foundation is not destroyed after all-and that its still-defiant survivors are preparing their revenge. Now the two exiled citizens of the Foundation-a renegade Councilman and the doddering historian-set out in search of the mythical planet Earth. . .and proof that the Second Foundation still exists. Meanwhile someone-or something-outside of both Foundations sees to be orchestrating events to suit its own ominous purpose. Soon representatives of both the First and Second Foundations will find themselves racing toward a mysterious world called Gaia and a final shocking destiny at the very end of the universe!

The continuing epic of Earth's first space colonists--and their fight against a repressive government to reclaim their world in the name of freedom.

The plot concerns a young woman biochemist who discovers that a chemical extracted from an unusual strain of lichen (hence the title) can be used to retard the ageing process enabling people to live to around 200-300 years. Wyndham speculates how society would deal with this prospect.

The two central characters are Diana Brackley and Francis Saxover, two biochemists who run parallel investigations into the properties of a specific species of lichen after Diana notices that a trace of the specimen prevents some milk turning sour.

She and Francis separately manage to extract from the lichen a new drug, dubbed Antigerone, which slows down the body's ageing process. While Francis uses it only on himself and his immediate family (without their knowledge), Diana founds a cosmetic spa, and builds up a clientele of some of the most powerful women in England, giving them low doses of Antigerone, preserving their beauty and youth. When Saxover finds out about the spas, he erroneously assumes that Diana's motive is profit. Diana's aim, however, is actually female empowerment, intending to gain the support of these influential women, believing that if Antigerone became publicly known, it would be reserved only for the men in power.

After a customer suffers an allergic reaction to one of Diana's products, the secret of the drug begins to emerge. Diana tries to cover up the real source of the drug, since the lichen is very rare and difficult to grow, but when it is finally discovered, she fakes her own death, in the hope of inspiring the women of Britain to fight for the rights she tried to secure for them.

Francis realizes that she may not really be dead, and tracks her down to a remote farm, where she has succeeded in growing a small amount of the lichen. Diana plans to rejoin the world under the guise of being her own sister, and continue the work she left off.

Before his trip to the stars, before the Rocinante, Amos Burton was confined to a Baltimore where crime paid you or killed you. Unless the authorities got to you first.

Set in the hard-scrabble solar system of Leviathan Wakes, Caliban's War, Abaddon's Gate and the upcoming Cibola Burn, The Churn expands the world of James S. A. Corey's acclaimed Expanse series. Anthologized in Paula Guran's The Year's Best Science Fiction & Fantasy Novellas 2015.

Born in 2008, Leisha Camden is beautiful, extraordinarily intelligent... and one of an ever-growing number of human beings who have been genetically modified to never require sleep.

Once she and "her kind" were considered interesting anomalies. Now they are outcasts - victims of blind hatred, political repression and shocking mob violence meant to drive the "Sleepless" from human society... and, ultimately, from the Earth itself.M

But Leisha Camden has chosen to remain behind in a world that envies and fears her "gift" - a world marked for destruction in a devastating conspiracy of freedom... and revenge.

A scientific experiment begins, and as the button is pressed, the unexpected occurs: everyone in the world goes to sleep for a few moments while everyone's consciousness is catapulted more than twenty years into the future. At the end of those moments, when the world reawakens, all human life is transformed by foreknowledge.

Altar the thief, a man of mystery and secret master of a gaudily decadent world.... a gargantuan spaceship designed to span civilisations... a desperate plunge into the heart of the sun... just the basic ingredients of the volcanic recipe that produces Charles L. Harness's shattering masterpiece.

At the center of the galaxy, a small band of humans, trapped on the barren world of Snowglade and facing extinction, discovers that they will play a new role in the order of the universe.

In the aftermath of an interstellar war an enigmatic star is discovered, travelling towards the Solar System from the galactic core. Its appearance adds a new and dangerous factor in the turbulent politics of the inhabited worlds as the rival factions - the power-holders of the ReUnited Nations, the rebels who secretly oppose their power, and the Religious Witnesses - all see advantages to be gained. But what awesome technology started the star on its journey half a million years ago - and why?

The passengers on the spaceship Argo, pursued by hostile ""mechs,"" must face their doubts about their captain's obsession with finding the galaxy's True Center, an obsession that even troubles the captain's son.

When the British Arean Company founded its Martian colony, it welcomed any settlers it could get. Outcasts, misfits and dreamers emigrated in droves to undertake the grueling task of terraforming the cold red planet--only to be abandoned when the BAC discovered it couldn't turn a profit on Mars.

This is the story of Mary Griffith, a determined woman with three daughters, who opened the only place to buy a beer on the Tharsis Bulge. It's the story of Manco Inca, whose attempt to terraform Mars brought a new goddess vividly to life; of Stanford Crosley, con man extraordinaire; of Ottorino Vespucci, space cowboy and romantic hero; of the Clan Morrigan, of the denizens of the Martian Motel, and of the machinations of another Company entirely, all of whom contribute to the downfall of the BAC and the founding of a new world. But Mary and her struggles and triumphs is at the center of it all, in her bar, the Empress of Mars.

Based on the Hugo-nominated novella of the same name, this is a rollicking novel of action, planetary romance, and high adventure.

Listen to the author read the novella version of this story at Green Man Review.

This multilayered epic of interstellar cabals and dark human passions is a profound exploration of genetics, environment, nurture, society, and the secrets of human intelligence.

In a futuristic world of cybernetics, two young friends become trapped in an endless nightmare of suspicion, surveillance, programmable servants, a centuries-old ruling class, and an enigmatic woman who dominates them all, in a story marked by genius, blackmail, sacrifice, murder, resurrection, the betrayal of innocence, and loyalty stronger than death.

This is the story of Ariane Emory: brilliant, corrupt, a genius in genetics, psychology, rape, and blackmail. She dominates the Council of Nine, as head of the Expansionist Party of the Multiworld Union, and is despot of the territory Reseune, where her laboratories create the one product essential to Cyteen: people. They are the "azi," human workers and soldiers artificially grown, computer trained, and owned by Reseune and hence by Ariane Emory. After one hundred and twenty years of life and fifty years of rule, Emory is murdered. But not for long...

This is the story of the Project: the plan to replicate Ariane Emory. Creatiing a genetic double is routine for Reseune's bio-technology, but nature is not nurture, and clones are still human beings. For the Project to succeed, Emory's followers have to subject the clone to every formative influence of the tyrant's life, keep her innocent of history, protect her from Emory's enemies, and oppress or silence anyone who might, even accidentally, disrupt the program.

This is also the story of Ari: a little girl driven to solve a mystery she can sense, but not define. A child thrown into a storm of global upheaval when her creation is made public, she inherits a stranger’s face and past, enemies and victims. She must wield her predecessor’s power to save herself, even from people she loves. And to survice, she must find out if she’s a puppet crafted by a dead megalomaniac – or the one person who can defuse a socio-genetic time bomb threatening to destroy her planet. For only Ariane Emory can save Cyteen...

In Beggars and Choosers, Kress returns to the same future world created in her earlier work, an America strangely altered by genetic modifications...

Most of the world is on the verge of collapse, overburdened by a population of jobless drones and racked by the results of irresponsible genetic research and nanotechnology. Will the world be saved? And for whom?

1962: A young Californian scientist finds his experiments spoiled by mysterious interference. Gradually his suspicions lead him to a shattering truth: scientists from the end of the century are using subatomic particles to send a message into the past, in the hope that history can be changed and a world-threatening catastrophe averted.

This is an omnibus edition of The Heliconia Trilogy.

Geneticist Pierre Tardivel may not have long to live-he's got a fifty-fifty chance of having the gene for Huntington's disease. But if his DNA is tragic, his girlfriend's is astonishing: Molly Bond has a mutation that gives her telepathy. Both of them have attracted the interest of Pierre's boss, Dr. Burian Klimus, a senior researcher in the Human Genome Project who just might be hiding a horrific past. Avi Meyer, a dogged Nazi hunter, thinks Klimus was the monstrous "Ivan the Terrible" of the Treblinka Death Camp.

As Pierre races against the ticking clock of his own DNA to make a world-changing scientific breakthrough, Avi also races against time to bring Klimus to justice before the last survivors of Treblinka pass away.

Ender’s Shadow explores the stars in this all-new novel...

At the end of Shadow of the Giant, Bean flees to the stars with three of his children--the three who share the engineered genes that gave him both hyper-intelligence and a short, cruel physical life. The time dilation granted by the speed of their travel gives Earth’s scientists generations to seek a cure, to no avail. In time, they are forgotten--a fading ansible signal speaking of events lost to Earth’s history. But the Delphikis are about to make a discovery that will let them save themselves, and perhaps all of humanity in days to come.

For there in space before them lies a derelict Formic colony ship. Aboard it, they will find both death and wonders--the life support that is failing on their own ship, room to grow, and labs in which to explore their own genetic anomaly and the mysterious disease that killed the ship’s colony.

George Poole isn't sure whether his life has reached a turning point or a dead end. At forty-five, he is divorced and childless, with a career that is going nowhere fast. Then, when his father dies suddenly, George stumbles onto a family secret: a sister he never knew existed. A twin named Rosa, raised in Rome by an enigmatic cult. Hoping to find the answers to the missing pieces of his life, George sets out for the ancient city.

Once in Rome, he learns from Rosa the enthralling story of their distant ancestor, Regina, an iron-willed genius determined to preserve her family as the empire disintegrates around her. It was Regina who founded the cult, which has mysteriously survived and prospered below the streets of Rome for almost two millennia. The Order, says Rosa, is her real family and, even if he doesn't realize it yet, it is George's family, too. When she takes him into the vast underground city that is the Order's secret home, he feels a strong sense of belonging, yet there is something oddly disturbing about the women he meets. They are all so young and so very much alike.

Stephen Baxter possesses one of the most brilliant minds in modern science fiction. His vivid storytelling skills have earned him comparison to the giants of the past: Clarke, Asimov, Stapledon. Like his great predecessors, Baxter thinks on a cosmic scale, spinning cutting-edge scientific speculation into pure, page-turning gold. Now Baxter is back with a breathtaking adventure that begins during the catastrophic collapse of Roman Britain and stretches forward into an unimaginably distant, war-torn future, where the fate of humanity lies waiting at the center of the galaxy....

The slaughter has begun. The mechs -- violent artificial intelligences dedicated to the total destruction of the human race -- have ravaged humanity's planets throughout the galaxy, forcing the survivors to flee to the Esty, a strange space-time continuum constructed by ancient beings near the galaxy's True Center.

In the Esty, the battered human race makes its final stand against the relentless mechs. It soon becomes hideously clear that young warrior Toby Bishop, his father Killeen, and his grandfather have become special targets that the mechs' terrifying design involves their capture, torture, and extinction.

One moment Joseph Schwartz is a happily retired tailor in Chicago, 1949. The next he's a helpless stranger on Earth during the heyday of the first Galactic Empire. Earth, as he soon learns, is a backwater, just a pebble in the sky, despised by all the other 200 million planets of the Empire because its people dare to claim it's the original home of man. And Earth is poor, with great areas of radioactivity ruining much of its soil--so poor that everyone is sentenced to death at the age of sixty. Joseph Schwartz is sixty-two.

This is young Isaac Asimov's first novel, full of wonders and ideas, the book that launched the novels of the Galactic Empire, culminating in the Foundation series. This is Golden Age SF at its finest.

"Niven has come up with an idea about as far out as one can get.... This is certainly classic science fiction-the idea is truly the hero." -Asimov's Science Fiction Magazine

When leaving Earth, the crew of the spaceship Discipline was prepared for a routine assignment. Dispatched by the all-powerful State on a mission of interstellar exploration and colonization, Discipline was aided (and secretly spied upon) by Sharls Davis Kendy, an emotionless computer intelligence programmed to monitor the loyalty and obedience of the crew. But what they weren't prepared for was the smoke ring-an immense gaseous envelope that had formed around a neutron star directly in their path. The Smoke Ring was home to a variety of plant and animal life-forms evolved to thrive in conditions of continual free-fall. When Discipline encountered it, something went wrong. The crew abandoned ship and fled to the unlikely space oasis.

Five hundred years later, the descendants of the Discipline crew living on the Smoke Ring no longer remember their origins. Earth is more myth than memory, and no recollection of the State remains. But Kendy remembers. And just outside the Smoke Ring, Discipline waits patiently to make contact with its wayward children.

Nancy Kress cemented her reputation in SF with the publication of her multiple-award-winning novella, "Beggars in Spain," which became the basis for her extremely successful Beggars Trilogy (comprising Beggars in Spain, Beggars and Choosers, and Beggars Ride).

And now she brings us Probability Space, the conclusion of the trilogy that began with Probability Moon and then Probability Sun, which is centered on the same world as Kress's Nebula Award-winning novelette, "Flowers of Aulit Prison." The Probability Trilogy has already been widely recognized as the next great work by this important SF writer.

In Probability Space, humanity's war with the alien Fallers continues, and it is a war we are losing. Our implacable foes ignore all attempts at communication, and they take no prisoners. Our only hope lies with an unlikely coalition: Major Lyle Kaufman, retired warrior Marbet Grant, the Sensitive who's involved with Kaufman Amanda, a very confused fourteen-year-old girl and Magdalena, one of the biggest power brokers in all of human space.

As the action moves from Earth to Mars to the farthest reaches of known space, with civil unrest back home and alien war in deep space, four humans--armed with little more than an unproven theory--try to enter the Fallers' home star system. It's a desperate gamble, and the fate of the entire universe may hang in the balance.

Robert J. Sawyer, the award-winning and bestselling writer, hits the peak of his powers in Humans, the second book of The Neanderthal Parallax, his trilogy about our world and parallel one in which it was the Homo sapiens who died out and the Neanderthals who became the dominant intelligent species. This powerful idea allows Sawyer to examine some of the deeply rooted assumptions of contemporary human civilization dramatically, by confronting us with another civilization, just as morally valid, that has made other choices. In Humans, Neanderthal physicist Ponter Boddit, a character you will never forget, returns to our world and to his relationship with geneticist Mary Vaughan, as cultural exchanges between the two Earths begin.

As we see daily life in another present-day world, radically different from ours, in the course of Sawyer's fast-moving story, we experience the bursts of wonder and enlightenment that are the finest pleasures of science fiction. Humans is one of the best SF novels of the year, and The Neanderthal Parallax is an SF classic in the making.

The Ugly Little Boy:

A small Neanderthal boy is brought into the future for scientific experimentation. The nurse who takes care of him, starts to see him as something other than a experimental subject.

The [Widget], the [Wadget], and Boff:

Only Robin could really see the Aliens...

During all recorded history, the Moon has hovered above our heads, a timeless symbol for lovers' ecstasy. Goddesses and Gibson Girls have tripped the light fantastic of her beams while sonneteers and scientists have scanned her changing phases.

Now man had actually reached the Moon, and on it the explorers found a structure, a formation so terrible and incomprehensible that it couldn't even be described in human terms. It was a thing that devoured men; that killed them again and again in torturous, unfathomable ways.

Earthbound are the only two men who could probe the thing: Al Barker, a homicidal maniac, whose loving mistress was death, and Dr. Edward Hawks, a scientific murderer, whose greatest mission was rebirth.

Plateau, a colony in the Tau Ceti system, was settled by humans some 300 years before the plot begins. The colony world itself is a Venusian type planet with a dense, hot, poisonous atmosphere. It would be otherwise uninhabitable, except for a tall monolithic mesa that rises 40 miles up into a breathable layer in the upper atmosphere. This gives the planet a habitable area about half the size of California. The Captain of the first colony vessel named the feature Mount Lookitthat (from his interjection at first sight of it), and the colony became known as Plateau.

After landing the slower-than-light ships, the Crew sign an agreement, called the Covenant of Planetfall, with their former passengers (who had just emerged from suspended animation and were in a weak bargaining position). This agreement gives the Crew (and their descendants in perpetuity) all control over the new colony. A system of medical care evolves, in which organ transplantation is the only method of treatment, even for cosmetic defects (such as baldness); a justice system evolves, with all crimes punishable by death, followed by involuntary donation of the decedent's transplantable organs (including skin, scalp, and teeth). Not surprisingly, only Colonists are ever arrested for crimes; and only Crew are eligible to receive transplants. Some Colonists become dissatisfied with the system and form a dissident group called the "Sons of Earth."

Joshua Kampa, the illegitimate son of a mute Spanish whore and a black serviceman, has always dreamed of Africa. But his dreams are of an Africa far in the past and are so vivid and in such hallucinatory detail that he is able to question the understanding of eminent palaeontologists. As a result, Joshua is invited to join a most unusual time travel project and is transported millions of years into the past of his dreams.

In early Pleistocene Africa, living among the prehuman species Homo habilis, experiencing the same hardships and the same intense pleasures, Joshua finds, for the first time in his troubled life, not only contentment but real love - a love that transcends almost everything. Intelligent, thoughtful and deeply moving, No Enemy But Time brilliantly evokes the remote past and, at the same time, presents a powerful and convincing portrayal of a relationship surmounting even the most daunting barriers. It is a challenging and highly original novel exploring the nature and origins of humankind.

In the free-fall environment of the Smoke Ring, the descendants of the crew of the Discipline no longer remembered their Earth roots -- or the existence of Sharls Davis Kendy, the computer-program despot of the ship. Until Kendy initiated contact once more.

Fourteen years later, only Jeffer, the Citizens Tree Scientist, knew that Kendy was still watching -- and waiting. Then the Citizens Tree people rescued a family of loggers and learned for the first time of the Admiralty, a large society living in free fall amid the floating debris called the Clump. And it was likely that the Admiralty had maintained, intact, Discipline's original computer library.

Exploration was a temptation neither Jeffer nor Kendy could resist, and neither Citizens Tree nor Sharls Davis Kendy would ever be the same again...

Throughout history, man has been searching for better ways to gather information about his universe. But although they may have longed for it, not even the most brilliant minds could conceive of a device as infinitely powerful or as immeasurably precise as the macroscope, until the twenty-first century. By analyzing information carried on macrons, this unbelievable tool brought the whole universe of wonders to man's doorstep. The macroscope was seen by many as the salvation of the human race.

But in the hands of the wrong man, the macroscope could be immensely destructive-infinitely more dangerous than the nuclear bomb. By searching to know too much, man could destroy the very essence of his mind. This is the powerful story of man's struggle with technology, and also the story of his human struggle with himself. This novel takes us across the breathtaking ranges of space as well as through the most touching places in the human heart. It is a story of coming of age, of sacrifice, and of love. It is the story of man's desperate search for a compromise between his mind and his heart, between knowledge and humanity.

Jack Havig, a man born with the ability to move at will through the past and the future of mankind, must save the world from a doomed future of tyranny before his time runs out.

In an Arizona desert a man wanders in a daze, speaking words that make no sense. Within twenty-four hours he is dead, his body swiftly cremated by his only known associates. Halfway around the world archaeologists make a shocking discovery at a medieval site. Suddenly they are swept off to the headquarters of a secretive multinational corporation that has developed an astounding technology. Now this group is about to get a chance not to study the past but to enter it. And with history opened to the present, the dead awakened to the living, these men and women will soon find themselves fighting for their very survival–six hundred years ago.

William Mandela is a genetic throwback, one of the small group of humans who fought and survived the Forever War. They returned to find humanity has evolved into a group mind called Man. Surrounded by a society that is too autocratic and intrusive, living a dull existence which cannot compare to the certainties of combat and feeling increasingly alienated, the veterans plan an escape to the future by means of space travel and relativity. But when their ship starts to fail, their journey becomes a search for the Unknown, the elusive entity responsible.

Charlie Johns has been snatched from his home on 61 North 34th Street and delivered to the strange future world of Ledom. Here, violence is a vague and improbable notion. Technology has triumphed over hunger, overpopulation, pollution, even time and space. But there is a change Charlie finds even more shocking: gender is a thing of the past. Venus Plus X is Theodore Sturgeon's brilliant evocation of a civilization for whom tensions between male and female and the human preoccupation with sex no longer exist.

As Charlie Johns explores Ledom and its people, he finds that the human precepts he holds dear are profane in this new world. But has Charlie learned all there is to know about this advanced society? And why are the Ledom so intent on gaining Charlie's approval? Unsettling, compelling, and no less than visionary, here is science fiction at its boldest: a novel whose wisdom and lyricism make it one of the most original and insightful speculations on gender ever produced.

At the end of Frank Herbert's final novel, Chapterhouse: Dune, a ship carrying a crew of refugees escapes into the uncharted galaxy, fleeing from a terrifying, mysterious Enemy.

Based directly on Frank Herbert's final outline, which lay hidden in two safe-deposit boxes for a decade, Sandworms of Dune will answer the urgent questions Dune fans have been debating for two decades: the origin of the Honored Matres, the tantalizing future of the planet Arrakis, the final revelation of the Kwisatz Haderach, and the resolution to the war between Man and Machine. This breathtaking new novel in Frank Herbert's Dune series has enough surprises and plot twists to please even the most demanding reader.

Not only is Lockstep the new center of the galaxy, but Toby is shocked to learn that the Empire is still ruled by its founding family: his own.
