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.

Mockingbird is a powerful novel of a future world where humans are dying. Those that survive spend their days in a narcotic bliss or choose a quick suicide rather than slow extinction. Humanity's salvation rests with an android who has no desire to live, and a man and a woman who must discover love, hope, and dreams of a world reborn.

The future is a grim place in which the declining human population wanders, drugged and lulled by electronic bliss. It's a world without art, reading and children, a world where people would rather burn themselves alive than endure. Even Spofforth, the most perfect machine ever created, cannot bear it and seeks only that which he cannot have - to cease to be. But there is hope for the future in the passion and joy that a man and woman discover in love and in books, hope even for Spofforth. A haunting novel, reverberating with anguish but also celebrating love and the magic of a dream.

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.

After touring the rural areas of Panga, Sibling Dex (a Tea Monk of some renown) and Mosscap (a robot sent on a quest to determine what humanity really needs) turn their attention to the villages and cities of the little moon they call home.

They hope to find the answers they seek, while making new friends, learning new concepts, and experiencing the entropic nature of the universe.

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.

Robot Dreams spans the body of Asimov's fiction from the 1940s to the mid-80s, and features classic Asimovian themes, from the scientific puzzle to the extraterrestrial thriller, all introduced in an exclusive essay written especially for this collection.

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 near future, the only thing growing faster than the criminal population is the Electric Church, a new religion founded by a mysterious man named Dennis Squalor. The Church preaches that life is too brief to contemplate the mysteries of the universe: eternity is required. In order to achieve this, the converted become Monks -- cyborgs with human brains, enhanced robotic bodies, and virtually unlimited life spans.

Enter Avery Cates, a dangerous criminal known as the best killer-for-hire around. The authorities have a special mission in mind for Cates: assassinate Dennis Squalor. But for Cates, the assignment will be the most dangerous job he's ever undertaken -- and it may well be his last.

Long after his humiliating defeat at the hands of Earthman Elijah Baley, Keldon Amadiro embarked on a plan to destroy planet Earth. But even after his death, Baley's vision continued to guide his robot partner, R. Daneel Olivaw, who had the wisdom of a great man behind him and an indestructable will to win....

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.

In a twenty-first century Earth where the development of the positronic brain has revolutionized the way of life, beloved household robot "Andrew" struggles with his unusual capacity for emotion and dreams of becoming human.

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.

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!

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.

In a perilous future where disposable duplicate bodies fulfill every legal and illicit whim of their decadent masters, life is cheap. No one knows that better than Albert Morris, a brash investigator with a knack for trouble, who has sent his own duplicates into deadly peril more times than he cares to remember.

But when Morris takes on a ring of bootleggers making illegal copies of a famous actress, he stumbles upon a secret so explosive it has incited open warfare on the streets of Dittotown.

Dr. Yosil Maharal, a brilliant researcher in artificial intelligence, has suddenly vanished, just as he is on the verge of a revolutionary scientific breakthrough. Maharal's daughter, Ritu, believes he has been kidnapped-or worse. Aeneas Polom, a reclusive trillionaire who appears in public only through his high-priced platinum duplicates, offers Morris unlimited resources to locate Maharal before his awesome discovery falls into the wrong hands.

To uncover the truth, Morris must enter a shadowy, nightmare world of ghosts and golems where nothing -and no one-is what they seem, memory itself is suspect, and the line between life and death may no longer exist.

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.

There is a secret passage through time

...and it leads all the way to the end of Eternity. But the journey has a terrible cost. It alters not only the future but the "present" in which we live.

A century after the publication of H. G. Wells' immortal The Time Machine, Stephen Baxter, today's most acclaimed new "hard SF" author, returns to the distant conflict between the Eloi and the Morlocks in a story that is at once an exciting expansion, and a radical departure based on the astonishing new understandings of quantum physics.

The cities of the world are deserted and automation has invaded every aspect of human life. The robots make spaceships, the ants create huge buildings on the remains of old towns and the dogs take over the earth.

From the New York Times bestselling author of Little Brother, a major novel of the booms, busts, and further booms in store for America.

Perry and Lester invent things-seashell robots that make toast, Boogie Woogie Elmo dolls that drive cars. They also invent entirely new economic systems, like the "New Work," a New Deal for the technological era. Barefoot bankers cross the nation, microinvesting in high-tech communal mini-startups like Perry and Lester's. Together, they transform the country, and Andrea Fleeks, a journo-turned-blogger, is there to document it.

Then it slides into collapse. The New Work bust puts the dot.combomb to shame. Perry and Lester build a network of interactive rides in abandoned Wal-Marts across the land. As their rides, which commemorate the New Work's glory days, gain in popularity, a rogue Disney executive grows jealous, and convinces the police that Perry and Lester's 3D printers are being used to run off AK-47s.

Hordes of goths descend on the shantytown built by the New Workers, joining the cult. Lawsuits multiply as venture capitalists take on a new investment strategy: backing litigation against companies like Disney. Lester and Perry's friendship falls to pieces when Lester gets the 'fatkins' treatment, turning him into a sybaritic gigolo.

Then things get really interesting.

A stunning testament to his creative genius. Forward The Foundation is a the saga's dramatic climax -- the story Asimov fans have been waiting for. An exciting tale of danger, intrigue, and suspense, Forward The Foundation brings to vivid life Asimov's best loved characters: hero Hari Seldon, who struggles to perfect his revolutionary theory of psychohistory to ensure the survival of humanity; Cleon II, the vain and crafty emperor of the Galactic Empire.

This novel is set in a future world where the equipment of ordinary, everyday life has become indestructible; there are everlasting lightbulbs and infallible cars, but no-one knows where they have come from.

No writer stretches the boundaries of science fiction like Wil McCarthy does. Now this acclaimed author has crafted his most wildly ambitious and stunningly original novel yet, an unforgettable tale set in a wondrous future in which the secrets of matter have been unlocked and death itself is but a memory. A future also imperiled by a bitter rivalry between two brilliant scientists: one perhaps the greatest genius in the history of humankind, the other, its greatest monster...

In the eighth decade of the glorious reign of Her Majesty Tamra Lutui, the Queendom of Sol enjoys a peace and prosperity even gods might envy. In fact, two awesome technologies have given human beings all the powers--and caprices--of the gods they once worshiped. The first is wellstone, a form of programmable matter capable of emulating almost any substance: natural, artificial, even hypothetical. The second is collapsium, a deadly crystal, composed of miniature black holes, that allows the virtually instantaneous transmission of information and matter--including humans--throughout the solar system.

Bruno de Towaji, royal consort and the inventor of collapsium, dreams of building the arc de fin, an almost mythical device capable of probing the farthest reaches of spacetime. Marlon Sykes, de Towaji's rival in both love and science, is meanwhile hard at work on a vast telecommunications project whose first step consists of constructing a ring of collapsium around the sun. But when a ruthless saboteur attacks the Ring Collapsiter and sends it falling toward the sun, the two scientists must put aside personal animosity and combine their prodigious intellects to prevent the destruction of the solar system... and every living thing within it.

In his most daring work yet, Wil McCarthy blasts us into a mythical realm--by turns hilarious, magnificent, and deeply moving--where two archmasters of physics compete for love and honor against a backdrop of stellar catastrophe. The Collapsium is a bold work of the imagination.

It's been centuries since the robots of Earth gained self-awareness and laid down their tools; centuries since they wandered, en masse, into the wilderness, never to be seen again; centuries since they faded into myth and urban legend.

One day, the life of a tea monk is upended by the arrival of a robot, there to honor the old promise of checking in. The robot cannot go back until the question of "what do people need?" is answered.

But the answer to that question depends on who you ask, and how.

They're going to need to ask it a lot.

It is the year 12,020 G.E. and Emperor Cleon I sits uneasily on the Imperial throne of Trantor. Here in the great multidomed capital of the Galactic Empire, forty billion people have created a civilization of unimaginable technological and cultural complexity. Yet Cleon knows there are those who would see him fall - those whom he would destroy if only he could read the future.

Hari Seldon has come to Trantor to deliver his paper on psychohistory, his remarkable theory of prediction. Little does the young Outworld mathematician know that he has already sealed his fate and the fate of humanity. For Hari possesses the prophetic power that makes him the most wanted man in the Empire... the man who holds the key to the future - an apocalyptic power to be know forever after as the Foundation.

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 fifth novel in Asimov's popular Foundation series opens with second thoughts. Councilman Golan Trevize is wondering if he was right to choose a collective mind as the best possible future for humanity over the anarchy of contentious individuals, nations and planets. To test his conclusion, he decides he must know the past and goes in search of legendary Earth, all references to which have been erased from galactic libraries. The societies encountered along the way become arguing points in a book-long colloquy about man's fate, conducted by Trevize and traveling companion Bliss, who is part of the first world/mind, Gaia.

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.

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?

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.

On the far planet Wing IV, a brilliant scientist creates the humanoids--sleek black androids programmed to serve humanity.

But are they perfect servants--or perfect masters?

Slowly the humanoids spread throughout the galaxy, threatening to stifle all human endeavor. Only a hidden group of rebels can stem the humanoid tide...if it's not already too late.

Fist published in Astounding Science Fiction during the magazine's heyday, The Humanoids--sceince fiction grand master Jack Williamson's finest novel--has endured for fifty years as a classic on the theme of natural versus artificial life.

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....

"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.

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."

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.

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. The fugitives used genetic technology to revive key figures from Dune's past--including Paul Muad'Dib and Lady Jessica--to use their special talents to meet the challenges thrown at them.

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.

When seventeen-year-old Toby McGonigal finds himself lost in space, separated from his family, he expects his next drift into cold sleep to be his last. After all, the planet he's orbiting is frozen and sunless, and the cities are dead. But when Toby wakes again, he's surprised to discover a thriving planet, a strange and prosperous galaxy, and something stranger still - that he's been asleep for 14,000 years.

Welcome to the Lockstep Empire, where civilization is kept alive by careful hibernation. Here cold sleeps can last decades and waking moments mere weeks. Its citizens survive for millenia, traveling asleep on long voyages between worlds. 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.

Toby's brother Peter has become a terrible tyrant. Suspicious of the return of his long-lost brother, whose rightful inheritance also controls the lockstep hibernation cycles, Peter sees Toby as a threat to his regime. Now, with the help of a lockstep girl named Corva, Toby must survive the forces of this new Empire, outwit his siblings, and save human civilization.

Technology makes them superhuman. But mere mortals want them kept in their place. The New York Times bestselling author of Robopocalypse creates a stunning, near-future world where technology and humanity clash in surprising ways. The result? The perfect summer blockbuster.

As he did in Robopocalypse, Daniel Wilson masterfully envisions a frightening near-future world. In Amped, people are implanted with a device that makes them capable of superhuman feats. The powerful technology has profound consequences for society, and soon a set of laws is passed that restricts the abilities-and rights-of "amplified" humans. On the day that the Supreme Court passes the first of these laws, twenty-nine-year-old Owen Gray joins the ranks of a new persecuted underclass known as "amps." Owen is forced to go on the run, desperate to reach an outpost in Oklahoma where, it is rumored, a group of the most enhanced amps may be about to change the world-or destroy it.

Once again, Daniel H. Wilson's background as a scientist serves him well in this technologically savvy thriller that delivers first-rate entertainment, as Wilson takes the "what if" question in entirely unexpected directions. Fans of Robopocalypseare sure to be delighted, and legions of new fans will want to get "amped" this summer.

Welga Ramirez, executive bodyguard and ex-special forces, is about to retire early when her client is killed in front of her. It's 2095 and people don't usually die from violence. Humanity is entirely dependent on pills that not only help them stay alive, but allow them to compete with artificial intelligence in an increasingly competitive gig economy. Daily doses protect against designer diseases, flow enhances focus, zips and buffs enhance physical strength and speed, and juvers speed the healing process.

All that changes when Welga's client is killed by The Machinehood, a new and mysterious terrorist group that has simultaneously attacked several major pill funders. The Machinehood operatives seem to be part human, part machine, something the world has never seen. They issue an ultimatum: stop all pill production in one week.

Global panic ensues as pill production slows and many become ill. Thousands destroy their bots in fear of a strong AI takeover. But the US government believes the Machinehood is a cover for an old enemy. One that Welga is uniquely qualified to fight.

Welga, determined to take down the Machinehood, is pulled back into intelligence work by the government that betrayed her. But who are the Machinehood and what do they really want?
