Search Worlds Without End

This much-anticipated second collection of stories is signature Ted Chiang, full of revelatory ideas and deeply sympathetic characters. In "The Merchant and the Alchemist's Gate," a portal through time forces a fabric seller in ancient Baghdad to grapple with past mistakes and the temptation of second chances. In the epistolary "Exhalation," an alien scientist makes a shocking discovery with ramifications not just for his own people, but for all of reality. And in "The Lifecycle of Software Objects," a woman cares for an artificial intelligence over twenty years, elevating a faddish digital pet into what might be a true living being. Also included are two brand-new stories: "Omphalos" and "Anxiety Is the Dizziness of Freedom."

In this fantastical and elegant collection, Ted Chiang wrestles with the oldest questions on earth--What is the nature of the universe? What does it mean to be human?--and ones that no one else has even imagined. And, each in its own way, the stories prove that complex and thoughtful science fiction can rise to new heights of beauty, meaning, and compassion.

Hugo Award-nominated Novelette

An explorer returns to gather information from a climate-ravaged Earth that his ancestors, and others among the planet's finest, fled centuries ago. The mission comes with a warning: a graveyard world awaits him. But so do those left behind -- hopeless and unbeautiful wastes of humanity who should have died out ages ago. After all this time, there's no telling how they've devolved. Steel yourself, soldier. Get in. Get out. And try not to stare.

The thrilling conclusion to the internationally bestselling Long Earth series explores the greatest question of all: What is the meaning of life?

2070-71. Nearly six decades after Step Day, a new society continues to evolve in the Long Earth. Now, a message has been received: "Join us."

The Next--the hyper-intelligent post-humans--realize that the missive contains instructions for kick-starting the development of an immense artificial intelligence known as The Machine. But to build this computer the size of an Earth continent, they must obtain help from the more populous and still industrious worlds of mankind.

Meanwhile, on a trek in the High Meggers, Joshua Valienté, now nearing seventy, is saved from death when a troll band discovers him. Living among the trolls as he recovers, Joshua develops a deeper understanding of this collective-intelligence species and its society. He discovers that some older trolls, with capacious memories, act as communal libraries, and live on a very strange Long Earth world, in caverns under the root systems of trees as tall as mountains.

Valienté also learns something much more profound... about life and its purpose in the Long Earth: We cultivate the cosmos to maximize the opportunities for life and joy in this universe, and to prepare for new universes to come.

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.

Riley, a veteran of interstellar war, is one of many beings from many different worlds aboard a ship on a pilgrimage that spans the galaxy. However, he is not journeying to achieve transcendence, a vague mystical concept that has drawn everyone else on the ship to this journey into the unknown at the far edge of the galaxy. His mission is to find and kill the prophet who is reputed to help others transcend. While their ship speeds through space, the voyage is marred by violence and betrayal, making it clear that some of the ship's passengers are not the spiritual seekers they claim to be.

Like the pilgrims in Chaucer's Canterbury Tales, a number of those on the starship share their unique stories. But as tensions rise, Riley realizes that the ship is less like the Canterbury Tales and more like a harrowing, deadly ship of fools. When he becomes friendly with a mysterious passenger named Asha, he thinks she's someone he can trust. However, like so many others on the ship, Asha is more than she appears. Uncovering her secrets could be the key to Riley's personal quest, or make him question everything he thought he knew about Transcendentalism and his mission to stop it.

It's been ten years since Handry was wrenched away from his family and friends, forced to wander a world he no longer understood. But with the help of the Ancients, he has cobbled together a life, of sorts, for himself and his fellow outcasts.

Wandering from village to village, welcoming the folk that the townships abandon, fighting the monsters the villagers cannot - or dare not - his ever-growing band of misfits has become the stuff of legend, a story told by parents to keep unruly children in line.

But there is something new and dangerous in the world, and the beasts of the land are acting against their nature, destroying the towns they once left in peace.

And for the first time in memory, the Ancients have no wisdom to offer...

Extraordinary new fiction set in the future India of River of Gods.

Ian McDonald's River of Gods called a "masterpiece" by Asimov's Science Fiction and praised by the Washington Post as a --"major achievement from a writer who is becoming one of the best SF novelists of our time"-- painted a vivid picture of a near future India, 100 years after independence. It revolutionized SF for a new generation by taking a perspective that was not European or American. Nominated for the Hugo Award and the Arthur C. Clarke Award, and winning the BSFA Award, the rich world of this novel has inspired McDonald to revisit its milieu in a series of short stories, all set in the world of River of Gods.

Cyberabad Days is a triumphant return to the India of 2047, a new, muscular superpower of one and a half billion people in an age of artificial intelligences, climate-change induced drought, water-wars, strange new genders, genetically improved children that age at half the rate of baseline humanity, and a population where males outnumber females four to one. India herself has fractured into a dozen states from Kerala to the headwaters of the Ganges in the Himalayas.

Cyberabad Days is a collection of seven stories, one Hugo nominee and one Hugo winner among them, as well as a thirty-one-thousand word original novella. As with everything Ian McDonald does, it is sure to be one of the most talked about books of the year.

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.

"A writer of boundless confidence and bold scientific extrapolation" (New York Times) concludes his mindbending trilogy.

Webmind-the vast consciousness that spontaneously emerged from the infrastructure of the World Wide Web-has proven its worth to humanity by aiding in everything from curing cancer to easing international tensions. But the brass at the Pentagon see Webmind as a threat that needs to be eliminated.

Caitlin Decter-the once-blind sixteen-year-old math genius who discovered, and bonded with, Webmind-wants desperately to protect her friend. And if she doesn't act, everything-Webmind included-may come crashing down.

When the renowned aviation hero and rabid isolationist Charles A. Lindbergh defeated Franklin Roosevelt by a landslide in the 1940 presidential election, fear invaded every Jewish household in America. Not only had Lindbergh, in a nationwide radio address, publicly blamed the Jews for selfishly pushing America toward a pointless war with Nazi Germany, but upon taking office as the thirty-third president of the United States, he negotiated a cordial "understanding" with Adolf Hitler, whose conquest of Europe and virulent anti-Semitic policies he appeared to accept without difficulty. What then followed in America is the historical setting for this startling new book by Pulitzer Prize-winner Philip Roth, who recounts what it was like for his Newark family -- and for a million such families all over the country -- during the menacing years of the Lindbergh presidency, when American citizens who happened to be Jews had every reason to expect the worst.

A sentient Ship with godlike powers (and aspirations) delivers the last survivors of humanity to a horrific, poisonous planet, Pandora--rife with deadly Nerve-Runners, Hooded Dashers, airborne jellyfish, and intelligent kelp. Chaplain/Psychiatrist Raja Lon Flattery is brought back out of hybernation to witness Ship's machinations as well as the schemes of human scientists manipulating the genetic structure of humanity. Sequel to Frank Herbert's Destination: Void, the first book in Herbert & Ransom's Pandora Sequence.

Spensa's life as a Defiant Defense Force pilot has been far from ordinary. She proved herself one of the best starfighters in the human enclave of Detritus and she saved her people from extermination at the hands of the Krell--the enigmatic alien species that has been holding them captive for decades. What's more, she traveled light-years from home as an undercover spy to infiltrate the Superiority, where she learned of the galaxy beyond her small, desolate planet home.

Now, the Superiority--the governing galactic alliance bent on dominating all human life--has started a galaxy-wide war. And Spensa's seen the weapons they plan to use to end it: the Delvers. Ancient, mysterious alien forces that can wipe out entire planetary systems in an instant. Spensa knows that no matter how many pilots the DDF has, there is no defeating this predator.

Except that Spensa is Cytonic. She faced down a Delver and saw something eerily familiar about it. And maybe, if she's able to figure out what she is, she could be more than just another pilot in this unfolding war. She could save the galaxy.

The only way she can discover what she really is, though, is to leave behind all she knows and enter the Nowhere. A place from which few ever return.

Valis is the first book in Philip K. Dick's incomparable final trio of novels (the others being are The Divine Invasion and The Transmigration of Timothy Archer).

This disorienting and bleakly funny work is about a schizophrenic hero named Horselover Fat; the hidden mysteries of Gnostic Christianity; and reality as revealed through a pink laser. Valis is a theological detective story, in which God is both a missing person and the perpetrator of the ultimate crime.

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.

Britain in the 21st century is a Balkanized mess. Moh Kohn is a security mercenary unaware that he holds the key to information which could change the world. Janis Taine is a scientist who needs Mohs help. And a rogue computer program is guiding events to a breathtaking conclusion.

Hominids is a strong, stand-alone SF novel, but it's also the first book of The Neanderthal Parallax, a trilogy that will examine two unique species of people. They are alien to each other, yet bound together by the never-ending quest for knowledge and, beneath their differences, a common humanity. We are one of those species, the other is the Neanderthals of a parallel world where they, not Homo sapiens, became the dominant intelligence. In that world, Neanderthal civilization has reached heights of culture and science comparable to our own, but is very different in history, society, and philosophy.

During a risky experiment deep in a mine in Canada, Ponter Boddit, a Neanderthal physicist, accidentally pierces the barrier between worlds and is transferred to our universe, where in the same mine another experiment is taking place. Hurt, but alive, he is almost immediately recognized as a Neanderthal, but only much later as a scientist. He is captured and studied, alone and bewildered, a stranger in a strange land. But Ponter is also befriended-by a doctor and a physicist who share his questing intelligence and boundless enthusiasm for the world's strangeness, and especially by geneticist Mary Vaughan, a lonely woman with whom he develops a special rapport.

Meanwhile, Ponter's partner, Adikor Huld, finds himself with a messy lab, a missing body, suspicious people all around, and an explosive murder trial that he can't possibly win because he has no idea what actually happened. Talk about a scientific challenge!

Contact between humans and Neanderthals creates a relationship fraught with conflict, philosophical challenge, and threat to the existence of one species or the other-or both-but equally rich in boundless possibilities for cooperation and growth on many levels, from the practical to the esthetic to the scientific to the spiritual. In short, Robert J. Sawyner has done it again.

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.

Life on New Mars is tough for humans, but death is only a minor inconvenience. The machines know their place, the free market rules all, and only the Abolitionists object.

Then a stranger arrives on New Mars, a clone who remember his life on Earth as Jonathan Wilde, the anarchist with a nuclear capability who was accused of losing World War III. This stranger also remembers one David Reid, who now serves as New Mars's leader. Long ago, it turns out, Wilde and Reid had shared ideals and fought over the same women.

Moving from 20th-century Scotland through a tumultuous 21st century and outward to humanity's settlement on a planet circling another star, The Stone Canal is idea-driven sci-fi at its best., making real and believable a future where long lives, strange deaths, and unexpected knowledge await those who survive the wars and revolutions to come.

Their hotel was beautifully situated, high on the northern slope of the huge artificial mound known as the paneium that was sacred to the goat-footed god. From here they had a total view of the city: the wide noble boulevards, the soaring obelisks and monuments, the palace of Hadrian just below the hill, the stately and awesome Library, the temple of Poseidon, the teeming marketplace, the royal lodge that Mark Antony had built after his defeat at Actium. And of course the Lighthouse, the wondrous many-windowed Lighthouse, the seventh wonder of the world, that immense pile of marble and limestone rising in majesty at the end of its mile-long causeway. Black smoke from the beacon-fire ar its summit curled lazily into the sky. The city was awakening.

It looked like the past, on Earth. But times had changed...and changed...and changed.

There were ghosts and chimeras and phastasies everywhere about. A burly thick-thighed swordsman appeared on the porch of the temple of Poseidon holding a Gorgon's severed head and waved it in a wide arc, grinning broadly. In the street below the hotel gate, three small pink sphinxes, no bigger than housecats, stretched and yawned and began to prowl the curbside. A larger one, lion-sized, watched warily from an alleyway: their mother, surely. Even at this distance he could hear her loud purring....

In M. John Harrison's dangerously illuminating new novel, three quantum outlaws face a universe of their own creation, a universe where you make up the rules as you go along and break them just as fast, where there's only one thing more mysterious than darkness.

In contemporary London, Michael Kearney is a serial killer on the run from the entity that drives him to kill. He is seeking escape in a future that doesn't yet exist—a quantum world that he and his physicist partner hope to access through a breach of time and space itself. In this future, Seria Mau Genlicher has already sacrificed her body to merge into the systems of her starship, the White Cat. But the "inhuman" K-ship captain has gone rogue, pirating the galaxy while playing cat and mouse with the authorities who made her what she is. In this future, Ed Chianese, a drifter and adventurer, has ridden dynaflow ships, run old alien mazes, surfed stellar envelopes. He "went deep"—and lived to tell about it. Once crazy for life, he's now just a twink on New Venusport, addicted to the bizarre alternate realities found in the tanks—and in debt to all the wrong people.

Haunting them all through this maze of menace and mystery is the shadowy presence of the Shrander—and three enigmatic clues left on the barren surface of an asteroid under an ocean of light known as the Kefahuchi Tract: a deserted spaceship, a pair of bone dice, and a human skeleton.

Outlink station Miranda has been destroyed by a nanomycelium and, because of this method of sabotage, the alien bioconstruct, Dragon – a creature as untrustworthy as it is gigantic – is thought to be involved. Sent on the titanic Polity dreadnought, the Occam Razor, Agent Cormac must investigate this, and resolve the question of Masada, a world about to be subsumed when the line of polity is drawn across it.

But the biophysicist Skellor has not been captured, and controls something so potent that Polity AIs are prepared to hunt him down forever, to prevent him using it.

On Masada the rebellion can never rise above ground as the slave population is subjugated by orbital laser arrays controlled by the Theocracy in their cylinder worlds, and by the fact that they cannot leave their compounds. For the wilderness of Masada is without breathable air, and out there roam the monstrous hooders, siluroynes, and the weird and terrible gabbleducks.

Ponter Boddit and his Homo sapiens lover, geneticist Mary Vaughan, are torn between two worlds, struggling to find a way to make their star-crossed relationship work. Aided by banned Neanderthal technology, they plan to conceive the first hybrid child, a symbol of hope for the joining of their two versions of reality.

But after an experiment shows that Mary's religious faith - something completely absent in Neanderthals - is a quirk of the neurological wiring of Homo sapiens brains, Ponter and Mary must decide whether their child should be predisposed to atheism or belief. Meanwhile, as Mary's Earth is dealing with a collapse of its planetary magnetic field, her boss, the enigmatic Jock Krieger, has turned envious eyes on the unspoiled Eden that is the Neanderthal world...

One thousand years after the Jupiter mission to explore the mysterious Monolith had been destroyed, after Dave Bowman was transformed into the Star Child, Frank Poole drifted in space, frozen and forgotten, leaving the supercomputer HAL inoperable. But now Poole has returned to life, awakening in a world far different from the one he left behind--and just as the Monolith may be stirring once again . . .

Fleeing the city of New York on the TransContinental atmospheric transport vehicle, Dran Florrian is traveling with Palimpsest -- the ultimate proof of a lifetime of scientific theorizing.

When a rogue organization attempts to steal the device, however, Dran takes drastic action.

But his invention threatens to destroy the very fabric of this and all other possible universes, unless Dran -- or someone very much like him -- can shut down the machine and reverse the process.

A generation after the events of The Long Earth, humankind has spread across the new worlds opened up by "stepping." A new "America" - Valhalla - is emerging more than a million steps from Datum - our Earth. Thanks to a bountiful environment, the Valhallan society mirrors the core values and behaviors of colonial America. And Valhalla is growing restless under the controlling long arm of the Datum government.

Soon Joshua, now a married man, is summoned by Lobsang to deal with a building crisis that threatens to plunge the Long Earth into a war unlike any humankind has waged before.

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?
