Search Worlds Without End

From junkies who drink at the time-stream to love affairs in time-reversed galaxies; from gene-altered dolphins that converse only in limericks to the program that allows you to design your own child; from the brain implants called axiomatics to the strange attractors that spin off new religions, Greg Egan's future is frighteningly close to our own present.

Tanner Mirabel was a security specialist who never made a mistake - until the day a woman in his care was blown away by Argent Reivich, a vengeful young postmortal. Tanner's pursuit of Reivich takes him across light-years of space to Chasm City, the domed human settlement on the otherwise inhospitable planet of Yellowstone.

But Chasm City is not what it was. The one-time high-tech utopia has become a Gothic nightmare: a nanotechnological virus has corrupted the city's inhabitants as thoroughly as it has the buildings and machines. Before the chase is done, Tanner will have to confront truths which reach back centuries, towards deep space and an atrocity history barely remembers.

When nuclear war breaks out and the nations of the Earth are destroyed, a group of US astronauts are marooned on the lunar surface. Using the "torsion field generator", a WWII Nazi Wunderwaffe previously known as the Bell, they hope to find an alternate Earth that did not suffer nuclear armageddon. But once they do discover one, how will they return home? They have a single Lunar Module, which can carry only four astronauts into lunar orbit...

Shana wakes up one morning to discover her little sister in the grip of a strange malady. She appears to be sleepwalking. She cannot talk and cannot be woken up. And she is heading with inexorable determination to a destination that only she knows. But Shana and her sister are not alone. Soon they are joined by a flock of sleepwalkers from across America, on the same mysterious journey. And like Shana, there are other "shepherds" who follow the flock to protect their friends and family on the long dark road ahead.

For on their journey, they will discover an America convulsed with terror and violence, where this apocalyptic epidemic proves less dangerous than the fear of it. As the rest of society collapses all around them--and an ultraviolent milita threatens to exterminate them--the fate of the sleepwalkers depends on unraveling the mystery behind the epidemic. The terrifying secret will either tear the nation apart--or bring the survivors together to remake a shattered world.

Nobody knows why there are only three hundred humans left alive on the Earth fifty million years from now. Opinion is fiercely divided on whether to settle in and plant the seed of mankind anew, or to continue using high-energy stasis fields, or "bobbles," in venturing into the future.

When somebody is murdered, it's obvious someone has a secret he or she is willing to kill to preserve.The murder intensifies the rift between the two factions, threatening the survival of the human race. It's up to 21st century detective Wil Brierson, the only cop left in the world, to find the culprit, a diabolical fiend whose lust for power could cause the utter extinction of man.

Filled with excitement and adventure, Vinge's tense SF puzzler will satisfy readers with its sense of wonder and engaging characters, one of whom is a murderer with a unique modus operandi.

Half a century after the Doomsday Battle, the uneasy balance of Dark Forest Deterrence keeps the Trisolaran invaders at bay. Earth enjoys unprecedented prosperity due to the infusion of Trisolaran knowledge. With human science advancing daily and the Trisolarans adopting Earth culture, it seems that the two civilizations will soon be able to co-exist peacefully as equals without the terrible threat of mutually assured annihilation. But the peace has also made humanity complacent.

Cheng Xin, an aerospace engineer from the early 21st century, awakens from hibernation in this new age. She brings with her knowledge of a long-forgotten program dating from the beginning of the Trisolar Crisis, and her very presence may upset the delicate balance between two worlds. Will humanity reach for the stars or die in its cradle?

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.

Professor Edward Kitchener, a double Nobel laureate researching quantum cosmology for the powerful Event Horizon conglomerate, has been savagely murdered. But was he the victim of industrial espionage, personal revenge, or a crime of passion by one of his handpicked team of live-wire students?

Event Horizon needs to know, and fast, so Greg Mandel, PSI-boosted veteran of the infamous Mindstar Battalion, must embark on an urgent investigation that ultimately leads him to an astounding confrontation with a past, which, according to the dead man's theories, might never have happened.

Identity crises, consumerism, and star-crossed teenage love in a futuristic society where people connect to the Internet via feeds implanted in their brains.

For Titus and his friends, it started out like any ordinary trip to the moon - a chance to party during spring break and play with some stupid low-grav at the Ricochet Lounge. But that was before the crazy hacker caused all their feeds to malfunction, sending them to the hospital to lie around with nothing inside their heads for days. And it was before Titus met Violet, a beautiful, brainy teenage girl who has decided to fight the feed and its omnipresent ability to categorize human thoughts and desires. Following in the footsteps of George Orwell, Anthony Burgess, and Kurt Vonnegut Jr., M. T. Anderson has created a not-so-brave new world — and a smart, savage satire that has captivated readers with its view of an imagined future that veers unnervingly close to the here and now.

Monumental devastation will sweep across the globe if the newly-discovered Hamner-Brown comet collides with the one major obstacle in its path: Earth.

For millionaire Tim Hamner, the comet is a ticket to immortality. For filmmaker Harvey Randall, it's a shot to redeem a flagging career. And for astronauts John Baker and Rick Delanty, it's a second chance for glory in outer space.

But for a world gripped by comet fever, fascination quickly turns to fear. And only those who survive the impact will know the even greater terror, when rich and poor, politicians and killers, turn to each other or against each other--and the remnants of humanity grow savage to battle for what little remains...

Vortex tells the story of Turk Findley, the protagonist introduced in Axis, who is transported ten thousand years into the future by the mysterious entities called "the Hypotheticals." In this future humanity exists on a chain of planets connected by Hypothetical gateways; but Earth itself is a dying world, effectively quarantined.

Turk and his young friend Isaac Dvali are taken up by a community of fanatics who use them to enable a passage to the dying Earth, where they believe a prophecy of human/Hypothetical contact will be fulfilled. The prophecy is only partly true, however, and Turk must unravel the truth about the nature and purpose of the Hypotheticals before they carry him on a journey through warped time to the end of the universe itself.

The 21st century was on the brink of nuclear confrontation when the 300 kilometer-long stone flashed out of nothingness and into Earth's orbit. NASA, NATO, and the UN sent explorers to the asteroid's surface...and discovered marvels and mysteries to drive researchers mad.

For the Stone was from space--but perhaps not our space; it came from the future--but perhaps not our future; and within the hollowed asteroid was Thistledown. The remains of a vanished civilization. A human--English, Russian, and Chinese-speaking--civilization. Seven vast chambers containing forests, lakes, rivers, hanging cities...

And museums describing the Death; the catastrophic war that was about to occur; the horror and the long winter that would follow. But while scientists and politicians bickered about how to use the information to stop the Death, the Stone yielded a secret that made even Earth's survival pale into insignificance.

What would happen if the world were ending?

A catastrophic event renders the earth a ticking time bomb. In a feverish race against the inevitable, nations around the globe band together to devise an ambitious plan to ensure the survival of humanity far beyond our atmosphere, in outer space.

But the complexities and unpredictability of human nature coupled with unforeseen challenges and dangers threaten the intrepid pioneers, until only a handful of survivors remain...

Five thousand years later, their progeny -- seven distinct races now three billion strong--embark on yet another audacious journey into the unknown... to an alien world utterly transformed by cataclysm and time: Earth.

On September 28th, a geologist working in Death valley finds a mysterious new cinder cone in very well-mapped area.

On October 1st, the government of Australia announces the discovery of an enormous granite mountain. Like the cinder cone, it wasn't there six months ago....

Something is happening to Planet Earth, and the truth is too terrifying to consider....

Golden Age SF meets Golden Age Crime from the author of Swiftly, New Model Army, and Yellow Blue Tibia-an innovative literary voice working at the height of his powers

Jack Glass is the murderer-we know this from the start. Yet as this extraordinary novel tells the story of three murders committed by Glass, the reader will be surprised to find out that it was Glass who was the killer and how he did it. And by the end of the book our sympathies for the killer are fully engaged. Riffing on the tropes of crime fiction (the country house murder, the locked room mystery) and imbued with the feel of golden age SF, this is another bravura performance from Roberts. Whatever games he plays with the genre, whatever questions he asks of the reader, Roberts never loses sight of the need to entertain.

This novel has some wonderfully gruesome moments, is built around three gripping HowDunnits, and comes with liberal doses of sly humor. Roberts invites us to have fun and tricks us into thinking about both crime and SF via a beautifully structured novel set in a society whose depiction challenges notions of crime, punishment, power, and freedom.

It's fifty years from tomorrow, and a black hole has accidentally fallen into the Earth's core. A team of scientists frantically searches for a way to prevent the mishap from causing harm, only to discover another black hole already feeding relentlessly at the core - one that could destroy the entire planet within two years.

But some even argue that the only way to save the Earth is to let its human inhabitants become extinct: to let the million-year evolutionary clock rewind and start all over again.

From an underground lab in New Zealand to a space station in Low Earth Orbit, from an endangered species conservation ark in Africa to a home in New Orleans, EARTH is a gripping novel peopled with extraordinary characters and abundant with challenging new ideas. Above all, it is an impassioned testament about our own responsibility to our endangered planet.

The story came about when, in 1988, Marty Greenberg suggested Asimov find someone who would take his forty-seven year old short story, "Nightfall", and - keeping the story essentially as written - add a detailed beginning and a detailed ending to it. This resulted in the 1990 publication of the novel, Nightfall by Isaac Asimov and Robert Silverberg. As Asimov relates in the Robert Silverberg chapter of his autobiography, "...Eventually, I received the extended Nightfall manuscript from Bob [Silverberg]... Bob did a wonderful job and I could almost believe I had written the whole thing myself. He remained absolutely faithful to the original story and I had very little to argue with.

These two renowned writers have invented a world not unlike our own--a world on the edge of chaos, torn between the madness of religious fanaticism and the stubborn denial of scientists. Only a handful of people on the planet Lagash are prepared to face the truth--that their six suns are setting all at once for the first time in 2,000 years, signaling the end of civilization!

The Peace War is quintessential hard-science adventure. The Peace Authority conquered the world with a weapon that never should have been a weapon--the "bobble," a spherical force-field impenetrable by any force known to mankind. Encasing governmental installations and military bases in bobbles, the Authority becomes virtually omnipotent. But they've never caught Paul Hoehler, the maverick who invented the technology, and who has been working quietly for decades to develop a way to defeat the Authority.

With the help of an underground network of determined, independent scientists and a teenager who may be the apprentice genius he's needed for so long, he will shake the world, in the fast-paced hard-science thriller that garnered Vinge the first of his four Hugo nominations for best novel.

The story of a man with a vision - immortality : for those who can afford it is found in cyberspace. Permutation city is the tale of a man with a vision - how to create immortality - and how that vision becomes something way beyond his control. Encompassing the lives and struggles of an artificial life junkie desperate to save her dying mother, a billionaire banker scarred by a terrible crime, the lovers for whom, in their timeless virtual world, love is not enough - and much more - Permutation city is filled with the sense of wonder.

For thirty years a tiny band of humans has been sheltering in the caverns of an airless, crater-pocked world called Michaelmas. Beyond their solar system lie the ruins of human interstellar civilization, stalked by a ruthless, infinitely patient cybernetic entity determined to root out the last few bands of survivors. One man has guided the people of Michaelmas through the hardest of times, and given them hope against the wolves: Miguel de Ruyter.

When a lone human ship blunders into their system, and threatens to lead the wolves to Michaelmas, de Ruyter embarks on a desperate, near-suicide mission to prevent catastrophe. But an encounter with a refugee from the ship - the enigmatic woman who calls herself only Glass - leads to de Ruyter's world being turned upside down.

Greg Mandel, late of the Mindstar Battalion, has been many things in his life. Commando. Freedom fighter. Assassin. Now he's a freelance operative with a very special edge: telepathy.

In the high-tech, hard-edged world of computer crime, zero-gravity smuggling, and artificial intelligence, Greg Mandel is the man to call when things get rough. But when an elusive saboteur plagues a powerful organization known as Event Horizon, Mandel must cut his way through a maze of corporate intrigue and startling new scientific discoveries.

And nothing less than the future is at stake.

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?

A century into the future, technology has solved most of the problems that have plagued our time. However, a new problem is on the horizon-one greater than humanity has ever faced. A massive asteroid is racing toward the earth, and its impact could destroy all life on the planet.

Immediately after the asteroid-named "Kali" after the Hindu goddess of chaos and destruction-is discovered, the world's greatest scientists begin their search for a way to prevent disaster. In the meantime, Captain Robert Singh, aboard the starship Goliath, may be the only person who can stop the asteroid. But this heroic role may demand the ultimate sacrifice.

The bestselling author of the classic Mars trilogy and The Years of Rice and Salt returns with a riveting new trilogy of cutting-edge science, international politics, and the real-life ramifications of global warming as they are played out in our nation’s capital—and in the daily lives of those at the center of the action. Hauntingly realistic, here is a novel of the near future that is inspired by scientific facts already making headlines.

When the Arctic ice pack was first measured in the 1950s, it averaged thirty feet thick in midwinter. By the end of the century it was down to fifteen. One August the ice broke. The next year the breakup started in July. The third year it began in May. That was last year.

It’s an increasingly steamy summer in the nation’s capital as Senate environmental staffer Charlie Quibler cares for his young son and deals with the frustrating politics of global warming. Charlie must find a way to get a skeptical administration to act before it’s too late—and his progeny find themselves living in Swamp World. But the political climate poses almost as great a challenge as the environmental crisis when it comes to putting the public good ahead of private gain.

While Charlie struggles to play politics, his wife, Anna, takes a more rational approach to the looming crisis in her work at the National Science Foundation. There a proposal has come in for a revolutionary process that could solve the problem of global warming—if it can be recognized in time. But when a race to control the budding technology begins, the stakes only get higher. As these everyday heroes fight to align the awesome forces of nature with the extraordinary march of modern science, they are unaware that fate is about to put an unusual twist on their work—one that will place them at the heart of an unavoidable storm.

With style, wit, and rare insight into our past, present, and possible future, this captivating novel propels us into a world on the verge of unprecedented change—in a time quite like our own. Here is Kim Stanley Robinson at his visionary best, offering a gripping cautionary tale of progress—and its price—as only he can tell it.

Earth was dying...

One fourth of its population was dead. The rest had little time to live.

A mass of interstellar matter had invaded the solar system, fling planets out of orbit and blocking off the sun. In that titanic disaster, Man had one small chance to survive: Appeal to an alien intelligence that might exist and that might - or might not - care enough to help!

A heart-stopping story of love, death, technology, and art set amid the tropics of a futuristic Brazil.

The lush city of Palmares Tres shimmers with tech and tradition, with screaming gossip casters and practiced politicians. In the midst of this vibrant metropolis, June Costa creates art that's sure to make her legendary. But her dreams of fame become something more when she meets Enki, the bold new Summer King. The whole city falls in love with him (including June's best friend, Gil). But June sees more to Enki than amber eyes and a lethal samba. She sees a fellow artist.

Together, June and Enki will stage explosive, dramatic projects that Palmares Tres will never forget. They will add fuel to a growing rebellion against the government's strict limits on new tech. And June will fall deeply, unfortunately in love with Enki. Because like all Summer Kings before him, Enki is destined to die.

Pulsing with the beat of futuristic Brazil, burning with the passions of its characters, and overflowing with ideas, this fiery novel will leave you eager for more from Alaya Dawn Johnson.

Carmen Dula and her husband have spent six years traveling to a distant solar system that is home to the enigmatic, powerful race known as "The Others," in the hopes of finding enough common purpose between their species to forge a delicate truce.

By the time Carmen and her party return, fifty years have been consumed by relativity-and the Earthlings have not been idle, building a massive flotilla of warships to defend Earth against The Others. But The Others have their own plans.

In the Nevada desert, an experiment has gone horribly wrong. A cloud of nanoparticles—micro-robots—has escaped from the laboratory. This cloud is self-sustaining and self-reproducing. It is intelligent and learns from experience. For all practical purposes, it is alive.

It has been programmed as a predator. It is evolving swiftly, becoming more deadly with each passing hour. Every attempt to destroy it has failed.

And we are the prey.

Compelling, challenging and resilient, over ten beautifully contained chapters, Clade canvasses three generations from the very near future to late this century. Central to the novel is the family of Adam, a scientist, and his wife Ellie, an artist.

Clade opens with them wanting a child and Adam in a quandary about the wisdom of this. Their daughter proves to be an elusive little girl and then a troubled teenager, and by now cracks have appeared in her parents' marriage. Their grandson is in turn a troubled boy, but when his character reappears as an adult he's an astronomer, one set to discover something astounding in the universe.

With great skill James Bradley shifts us subtly forward through the decades, through disasters and plagues, miraculous small moments and acts of great courage. Elegant, evocative, understated and thought-provoking, it is the work of a writer in command of the major themes of our time.

Ellen May Ngewthu is a young woman with centuries of experience, a soldier and leader of the Cassini Division, the elite defense force of the utopian Solar Union. Here in the twenty-fourth century, the forts of the Division, in orbit around a mysteriously transformed Jupiter, are the front line in humanity's long standoff with the unknowable posthumans--godlike and remote beings descended from the people who transformed themselves with high technology centuries ago.

The posthumans' capacities are unknown . . . but we know they disintegrated Ganymede, we know they punched a wormhole into Jovian space, and we know that the very surface of the solar system's largest planet has been altered by their incomprehensible artifacts. Worst of all, we know that they have been bombarding the solar system with powerful data viruses for generations.

Now Ellen has a plan to rid humanity of this threat once and for all. But she needs to recruit the right people to her cause--and convince them to mistrust the posthumans as much as she does.

Her quest will take her to the mid-Atlantic towers of Solar Union Earth, to the green ruins of London, and, in the farthest reaches of human space, to the long-separated libertarian colony of New Mars. In the process, much will be revealed--about history, about power, and about what it is to be human.

When corporations go to war, standard business practice goes out the window. Astro Corporation is led by indomitable Texan Pancho Lane, Humphries Space Systems by the rich and ruthless Martin Humphries, and their fight is over nothing less than resources of the Asteroid Belt itself. As fighting escalates, the lines between commerce and politics, boardroom and bedroom, blur--and the keys to victory will include physics, nanotechnology, and cold hard cash.

As they fight it out, the lives of thousands of innocents hang in the balance, including the rock rats who make their living off the asteroids, and the inhabitants of Selene City on Earth's moon. As if matters weren't complicated enough, the shadowy Yamagata corporation sets its sights on taking advantage of other people's quarrels, and space pirate Lars Fuchs decides it's time to make good on his own personal vendetta.

It's a breakneck finale that can end only in earth's salvation--or the annihilation of all that humankind has ever accomplished in space.

Marak has suffered the madness his entire life. He is a prince and warrior, strong and shrewd and expert in the ways of the desert covering his planet. In the service of his father, he has dedicated his life to overthrowing the Ila, the mysterious eternal dictator of his world. For years he has successfully hidden the visions that plague him -- voices pulling him eastward, calling Marak, Marak, Marak, amid mind-twisting visions of a silver tower. But when his secret is discovered, Marak is betrayed by his own father and forced to march in an endless caravan with the rest of his world's madmen to the Ila's city of Oburan.

Instead of death, Marak finds in Oburan his destiny, and the promise of life -- if he can survive what is surely a suicidal mission. The Ila wants him to discover the source of the voices and visions that afflict the mad. Despite the danger sof the hostile desert, tensions within the caravan, and his own excruciating doubts, Marak miraculously reaches his goal -- only to be given another, even more impossible mission by the strange people in the towers.

According to these beings who look like him yet act differently than anyone he has ever known, Marak has a slim chance to save his world's people from the wrath of Ila's enemies. But to do so, he must convince them all -- warring tribes, villagers, priests, young and old, as well as the Ila herself -- to follow him on an epic trek across the burning desert before the hammer of the Ila's foes falls from the heavens above.

It is the twenty-first century. Earth's space program is thriving, with a colony in place in the Moon. And then an incredible discovery is made on the lunar farside. A massive structure is being erected by living machines--microscopically small, intelligent, unstoppable, consuming whatever they touch. All who come near them die horribly. Meanwhile, the mysterious structure continues to grow, expand, take shape. And its creators begin to multiply....

Is this the first strike in an alien invasion from the stars? Or has human nanotech experimentation gone awry, triggering a long-predicted disaster? As riots rage across a panicked Earth, scientists on Earth and on the Moon race to learn the truth before humanity's home is engulfed by the voracious machines and its inhabitants perish in the most terrifying plague ever known.

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.

Four men and a woman are reduced to a microscopic fraction of their original size, sent in a miniaturized atomic sub through a dying man's carotid artery to destroy a blood clot in his brain. If they fail, the entire world will be doomed.

When a giant meteor crashes into the earth and destroys all life, the small group of human survivors manage to leave the barren planet and establish a new home on the moon. From Tycho Base, men and woman are able to observe the devastated planet and wait for a time when return will become possible.

Generations pass. Cloned children have had children of their own, and their eyes are raised toward the giant planet in the sky which long ago was the cradle of humanity. Finally, after millennia of waiting, the descendants of the original refugees travel back to a planet they've never known, to try and rebuild a civilization of which they've never been a part.

The fate of the earth lies in the success of their return, but after so much time, the question is not whether they can rebuild an old destroyed home, but whether they can learn to inhabit an alien new world--Earth.

Farside, the side of the Moon that never faces Earth, is the ideal location for an astronomical observatory. It is also the setting for a tangled web of politics, personal ambition, love, jealousy, and murder.

Telescopes on Earth have detected an Earth-sized planet circling a star some thirty light-years away. Now the race is on to get pictures of that distant world, photographs and spectra that will show whether or not the planet is truly like Earth, and if it bears life.

Farside will include the largest optical telescope in the solar system as well as a vast array of radio antennas, the most sensitive radio telescope possible, insulated from the interference of Earth's radio chatter by a thousand kilometers of the Moon's solid body.

Building the Farside observatory is a complex, often dangerous task. On the airless surface of the Moon, under constant bombardment of hard radiation and infalling micrometeoroids, builders must work in cumbersome spacesuits and use robotic machines as much as possible. Breakdowns - mechanical and emotional - are commonplace. Accidents happen, some of them fatal.

What they find stuns everyone, and the human race will never be the same.
