Search Worlds Without End

Michael Poole's wormholes constructed in the orbit of Jupiter had opened the galaxy to humankind. Then Poole tried looping a wormhole back on itself, tying a knot in space and ripping a hole in time.

It worked. Too well.

Poole was never seen again. Then from far in the future, from a time so distant that the stars themselves were dying embers, came an urgent SOS--and a promise. The universe was doomed, but humankind was not. Poole had stumbled upon an immense artifact, light-years across, fabricated from the very string of the cosmos.

The universe had a door. And it was open...

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.

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.

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.

An amazing breakthrough in genetic engineering made by Vergil Ulam is considered too dangerous for further research, but rather than destroy his work, he injects himself with his creation and walks out of his lab, unaware of just quite how his actions will change the world. Author Greg Bear's treatment of the traditional tale of scientific hubris is both suspenseful and a compelling portrait of a new intelligence emerging amongst us, irrevocably changing our world.

When the storm got bad, scientist Frank Vanderwal was at work, formalizing his return to the National Science Foundation for another year. He'd left the building just in time to help sandbag at Arlington Cemetery. Now that the torrent was over, large chunks of San Diego had eroded into the sea, and D.C. was underwater.

Shallow lakes occupied the most famous parts of the city. Reagan Airport was awash and the Potomac had spilled beyond its banks. Rescue boats dotted the saturated cityscape. Everything Frank and his colleagues in the halls of science and politics feared had culminated in this massive disaster. And now the world looked to them to fix it.

Whatever Frank can do, now that he is homeless, he'll have to do from his car. He's not averse to sleeping outdoors. Years of research have made him hyperaware of his status as just another primate. That plus his encounter with a Tibetan Buddhist has left him resolved to live a more authentic life.

Hopefully, this will prepare him for whatever is to come.

For even as D.C. bails out from the flood, a more extreme climate change looms. With the melting of the polar ice caps shutting down the warm waters of the Gulf Stream, another Ice Age could be imminent. The last time it happened, eleven thousand years ago, it took just three years to start.

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.

Asimov combines many of his science fiction favorites from the thirties with his personal reflections on his early years, interests, and influences.

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.

By the time Phil Chase is elected president, the world’s climate is far on its way to irreversible change. Food scarcity, housing shortages, diminishing medical care, and vanishing species are just some of the consequences. The erratic winter the Washington, D.C., area is experiencing is another grim reminder of a global weather pattern gone haywire: bone-chilling cold one day, balmy weather the next.

But the president-elect remains optimistic and doesn’t intend to give up without a fight. A maverick in every sense of the word, Chase starts organizing the most ambitious plan to save the world from disaster since FDR–and assembling a team of top scientists and advisers to implement it.

For Charlie Quibler, this means reentering the political fray full-time and giving up full-time care of his young son, Joe. For Frank Vanderwal, hampered by a brain injury, it means trying to protect the woman he loves from a vengeful ex and a rogue “black ops” agency not even the president can control–a task for which neither Frank’s work at the National Science Foundation nor his study of Tibetan Buddhism can prepare him.

In a world where time is running out as quickly as its natural resources, where surveillance is almost total and freedom nearly nonexistent, the forecast for the Chase administration looks darker each passing day. For as the last–and most terrible–of natural disasters looms on the horizon, it will take a miracle to stop the clock . . . the kind of miracle that only dedicated men and women can bring about.

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.

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.

Four men were on board the atomic subtug Fenian Ram S1881. They were on a mission to steal vitally needed oil from underwater deposits in enemy territory - a mission from which none of the last tugs had returned..

Four men who knew everything they had to know about one another - except which one of them was the saboteur who could destroy them all.

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.

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.

One of the most respected writers of hard SF, it has been more than ten years since Joan Slonczewski's last novel. Now she returns with a spectacular tour de force of the college of the future, in orbit. Jennifer Ramos Kennedy, a girl from a rich and politically influential family (a distant relation descended from the famous Kennedy clan), whose twin brother has died in an accident and left her bereft, is about to enter her freshman year at Frontera College.

Frontera is an exciting school built with media money, and a bit from tribal casinos too, dedicated to educating the best and brightest of this future world. We accompany Jenny as she proceeds through her early days at school, encountering surprises and wonders and some unpleasant problems. The Earth is altered by global warming, and an invasive alien species called ultraphytes threatens the surviving ecosystem. Jenny is being raised for great things, but while she's in school she just wants to do her homework, go on a few dates, and get by. The world that Jenny is living in is one of the most fascinating and creative in contemporary SF, and the problems Jenny faces will involve every reader, young and old.

In 1977 Frederik Pohl stunned the science fiction world with the publication of Gateway, one of the most brilliantly entertaining SF novels of all time. Gateway was a bestseller and won science fiction's triple crown: the Hugo, Nebula, and John W. Campbell Memorial awards for best novel. Now, more than twenty-five years later, Pohl has completed a new novel set in the Gateway universe. The Boy Who Would Live Forever has a sense of wonder and excitement that will satisfy those who loved Gateway and will delight new readers as well.

In Gateway, long after the alien Heechee abandoned their space-station, Gateway (as humans dubbed it) allowed humans to explore new worlds. The Heechee, alarmed by the alien Kugel whose goal was to destroy all organic lifeforms, had already retreated to the galactic core where they now lived in peace. Now, in The Boy Who Would Live Forever, humans with dreams of life among the stars are joining the Heechee at the core, to live there along with those humans and Heechee whose physical bodies have died and their minds stored in electronic memory so that their wisdom passes down through the ages.

Their peace is threatened by the Kugel, who may yet attack the core. But a much greater threat is the human Wan Enrique Santos-Smith, whose blind loathing of the Heechee fuels an insane desire to destroy them and, incidentally, every living being in the galaxy.

Stan and Estrella, two young people from Earth, went to Gateway looking for adventure, and found each other. They settle among the Heechee on Forested Planet of Warm Old Star Twenty-Four, never suspecting that they may be the last best hope to save the galaxy. But with allies like Gelle-Klara Moynlin--one of the galaxy's richest women, who isn't content to just have money, but wants to use her wealth for good, and machine mind Marc Antony-a wonderful chef to thousands of living and stored clients, they are destined to contend with Wan's terrible plan. Frederik Pohl has woven together the lives of these and other memorable characters to create a masterful new novel.

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.
