Greg Egan

Greg Egan is arguably Australia's greatest living science fiction writer. In a career spanning more than thirty years, he has produced a steady stream of novels and stories that address a wide range of scientific and philosophical concerns: artificial intelligence, higher mathematics, science vs religion, the nature of consciousness, and the impact of technology on the human personality. All these ideas and more find their way into this generous and illuminating collection, the clear product of a man who is both a master storyteller and a rigorous, exploratory thinker.The Best of Greg Egan contains twenty stories and novellas arranged in chronological order, and each of them is a brilliantly conceived, painstakingly developed gem, including the Hugo Award-winning novella "Oceanic", a powerful account of a boy whose deeply held religious beliefs are undermined by what he comes to learn about the laws of the physical world.This book really does represent the best of Greg Egan, and it therefore takes its place among the best of contemporary SF. Startling, intelligent and always hugely entertaining, it provides an ideal introduction to one of the most accomplished and original writers working today. This is an important and provocative collection, and it deserves a place on the serious science fiction reader's permanent shelf.

Twenty Stories and Novellas from Hugo, Campbell, and Locus Award Winner Greg Egan, Arguably Australia's Greatest Living Science Fiction Writer In a career spanning more than thirty years, Greg Egan has produced a steady stream of novels and stories that address a wide range of scientific and philosophical concerns: artificial intelligence, higher mathematics, science vs religion, the nature of consciousness, and the impact of technology on the human personality. All these ideas and more find their way into this generous and illuminating collection, the clear product of a man who is both a master storyteller and a rigorous, exploratory thinker. The Best of Greg Egan contains twenty stories and novellas arranged in chronological order, and each of them is a brilliantly conceived, painstakingly developed gem. The book opens with "Learning to be Me," about a society in which the organic human brain can be replaced by a miraculous piece of technology called "the jewel," a "mock brain" that confers, among other things, a kind of immortality on its recipients. "Bit Players" - the opening movement in a trio of tales that continues with "3-adica" and "Instantiation" - posits a world in which cheaply generated software beings are exploited for the basest commercial purposes. (Other sets of interconnected stories - all of them reprinted here - include the mathematically-themed "Luminous" and "Dark Integers," and a pair of stories centered on the complex marriage of a physicist and a mathematician: "Singleton" and "Oracle.") "Reasons to be Cheerful" concerns a young boy whose brain tumor has an unexpected effect on his life, moods, and view of the world. "Axiomatic" tells the story of a society in which "implants" can be used to alter the human personality, with potentially lethal results. And the Hugo Award-winning novella "Oceanic" is a powerful account of a boy whose deeply held religious beliefs are undermined by what he comes to learn about the laws of the physical world. This book really does represent the best of Greg Egan, and it therefore takes its place among the best of contemporary SF. Startling, intelligent and always hugely entertaining, it provides an ideal introduction to one of the most accomplished and original writers working today. This is an important and provocative collection, and it deserves a place on the serious science fiction reader's permanent shelf.

An unabridged collection spotlighting the "best of the best" hard science fiction stories published in 2018 by current and emerging masters of the genre, edited by Allan Kaster. In "3-adica," by Greg Egan, sentient characters in an online multiplayer game hack the operating systems of their host machines to escape to a refuge that's only rumored to exist. Struggling colonists, on a world subject to periodic bursts of radiation from its primary's UV-emitting companion, go on an expedition to recover a critical package from Earth in "Umbernight," by Carolyn Ives Gilman. In "Icefall," by Stephanie Gunn, the Mountain on the planet, Icefall, holds the mystery to a lost colony and is an irresistible, fatal allure to the climbers of the universe; but no one ever returns from the Mountain. A mother seeks revenge on the doctor that changed her neuro-atypical son's personality with a deep brain stimulation implant in "The Woman Who Destroyed Us," by S.L. Huang. In "Entropy War," by Yoon Ha Lee, a conquering alien race at the height of their powers, retreats into an arkworld to win the ultimate war in the only way they can. An AI piloting an island-ship, that used to be the Earth, struggles to make sense of the universe as the last stars are dying out in "Cosmic Spring," by Ken Liu. In "Nothing Ever Happens on Oberon," by Paul McAuley, set in the author's Quiet War universe, a supervisor of a mining operation on the moon, Oberon, investigates the crash-landing of an ancient escape pod. In depression-era Alaska, a desperate bush pilot reluctantly accepts an illegal charter from a pair of scientists investigating a legendary mirage in Glacier National Park in "The Spires," by Alec Nevala-Lee. In "Providence," by Alastair Reynolds, the crew of a crippled starship, unable to complete its mission, decides to salvage its expedition by providing future exploratory ships with data they did not have. A disillusioned cr che manager leaves Luna to work on an asteroid-based cr che and then must decide whether or not to return to Luna in "Intervention," by Kelly Robson. And finally, an entity that controls the solar system wants aid against another entity from a reconstructed human it just created, in "Kindred," by Peter Watts.

Greg Egan's Perihelion Summer is a story of people struggling to adapt to a suddenly alien environment, and the friendships and alliances they forge as they try to find their way in a world where the old maps have lost their meaning.Taraxippus is coming: a black hole one tenth the mass of the sun is about to enter the solar system.Matt and his friends are taking no chances. They board a mobile aquaculture rig, the Mandjet, self-sustaining in food, power and fresh water, and decide to sit out the encounter off-shore. As Taraxippus draws nearer, new observations throw the original predictions for its trajectory into doubt, and by the time it leaves the solar system, the conditions of life across the globe will be changed forever.Praise for Perihelion Summer"Egan here doubles down on climate change with his typically rigorous exploration of a cosmic accident's effect on Earth and all its people. His characters are sharp and funny and their courageous response to the massive challenge they face works as a spur to cause us to think--why couldn't we do as well with our own great challenge? This is what the best science fiction can do that no other genre can, and we need it now more than ever. Bravo " -- Kim Stanley Robinson

?Hugo Award–winning hard science fiction master Greg Egan returns with a new novel featuring one of science fiction’s most unusual worlds. Seth is a surveyor, along with his friend Theo, a leech-like creature running through his skull who tells Seth what lies to his left and right. Theo, in turn, relies on Seth for mobility, and for ordinary vision looking forwards and backwards. Like everyone else in their world, they are symbionts, depending on each other to survive. In the universe containing Seth's world, light cannot travel in all directions: there is a “dark cone” to the north and south. Seth can only face to the east (or the west, if he tips his head backwards). If he starts to turn to the north or south, his body stretches out across the landscape, and to rotate as far as north-north-east is every bit as impossible as accelerating to the speed of light. Every living thing in Seth’s world is in a state of perpetual migration as they follow the sun’s shifting orbit and the narrow habitable zone it creates. Cities are being constantly disassembled at one edge and rebuilt at the other, with surveyors mapping safe routes ahead. But when Seth and Theo join an expedition to the edge of the habitable zone, they discover a terrifying threat: a fissure in the surface of the world, so deep and wide that no one can perceive its limits. As the habitable zone continues to move, the migration will soon be blocked by this unbridgeable void, and the expedition has only one option to save its city from annihilation: descend into the unknown.

Hard science fiction's grand master delivers the stunning conclusion to his Orthogonal trilogy. In a universe where the laws of physics and the speed of light are completely alien to our own, the travelers on the ship Peerless have completed a generations-long struggle to develop advanced technology in a desperate attempt to save their home world. But as tensions mount over the risks of turning the ship around and starting the long voyage home, a new complication arises: the prospect of constructing a messaging system that will give the Peerless news of its own future. While some see this as a guarantee of safety and a chance to learn of their mission's ultimate success, others are convinced that the knowledge will be oppressive or worse--that the system could be abused. The conflict over this proposed communication system tears the travelers' society apart, culminating in terrible violence. To save the Peerless and its mission, two rivals must travel to a world where time runs in reverse. Continuing the epic multiple generation-spanning scope of The Clockwork Rocket and The Eternal Flame, Greg Egan's Orthogonal series has continuously pushed the boundaries of scientific fiction without ever losing track of the lives of the individuals carrying out this grand mission. The Arrows of Time brings this fascinating space opera to a close.

When the laws of physics are suddenly called into question, a whole new potential for life and death is brought to the entire universe.For twenty thousand years, every phenomenon that has ever been observed in the universe has been explainable through the means of the Sarumpaet Rules. These rules are the essential laws of quantum graphs that explain the makeup of the geometric structure of space-time.Cass, a humanoid physicist from Earth, discovers that the Sarumpaet Rules may not be the only applicable set of the laws of physics in the universe. Cass travels to a remote experimental facility in hopes to test her theory?that the ?novo-vacuum” will begin to decay the moment it is created. Cass’s theory proves greater than she’d anticipated, and the ?novo-vacuum” begins to expand out from the research facility at half the speed of light.More than six hundred years pass, and at least two thousand inhabited systems have been consumed by the ?novo-vacuum.” Those fascinated by the phenomenon choose to study it under two differing categories: Preservationists and Yielders. Preservationists are forever hypothesizing on how to destroy the vacuum; Yielders believe it holds a purpose in reinvigorating civilization.Tchicaya is a Yielder and Mariama is a Preservationist. These childhood friends will put their beliefs and their history to the test when violence breaks out among the two groups. Tchicaya must form an alliance with Mariama so that she can help them both escape the violence and confront the fate of the universe before it is too late.Skyhorse Publishing, under our Night Shade and Talos imprints, is proud to publish a broad range of titles for readers interested in science fiction (space opera, time travel, hard SF, alien invasion, near-future dystopia), fantasy (grimdark, sword and sorcery, contemporary urban fantasy, steampunk, alternative history), and horror (zombies, vampires, and the occult and supernatural), and much more.

A quantum Brave New World from the boldest and most wildly speculative writer of his generation. “Greg Egan is perhaps the most important SF writer in the world."—Science Fiction Weekly "One of the very best "—Locus. "Science fiction with an emphasis on science."—New York Times Book ReviewSince the Introdus in the twenty-first century, humanity has reconfigured itself drastically. Most chose immortality, joining the polises to become conscious software. Others opted for gleisners: disposable, renewable robotic bodies that remain in contact with the physical world of force and friction. Many of these have left the solar system forever in fusion-drive starships.And there are the holdouts: the fleshers left behind in the muck and jungle of Earth—some devolved into dream apes, others cavorting in the seas or the air—while the statics and bridgers try to shape out a roughly human destiny.But the complacency of the citizens is shattered when an unforeseen disaster ravages the fleshers and reveals the possibility that the polises themselves might be at risk from bizarre astrophysical processes that seem to violate fundamental laws of nature. The orphan Yatima, a digital being grown from a mind seed, joins a group of citizens and flesher refugees in a search for the knowledge that will guarantee their safety—a search that puts them on the trail of the ancient and elusive Transmuters, who have the power to reshape subatomic particles, and to cross into the macrocosmos, where the universe we know is nothing but a speck in the higher-dimensional vacuum.Skyhorse Publishing, under our Night Shade and Talos imprints, is proud to publish a broad range of titles for readers interested in science fiction (space opera, time travel, hard SF, alien invasion, near-future dystopia), fantasy (grimdark, sword and sorcery, contemporary urban fantasy, steampunk, alternative history), and horror (zombies, vampires, and the occult and supernatural), and much more.

“Egan is determined to make sense of everything – to understand the whole world as an intelligible, rational, material (and finally manipulable) realm – even if it means abandoning comfortable and comforting illusions. This is fundamental to the whole project of SF and it’s why Egan’s Best – and his Rest – is worth any number of looks. —Locus What happens when your digital self overpowers your physical self?A life in Permutation City is unlike any life to which you’re accustomed.

After generations of travel, the spaceship Peerless may finally have achieved its goal - but the decision to return home may create more tensions than ever before.

Classic hard science fiction from a master. The generation ship Peerless is running out of space, and fuel - and prospects for survival ...

Greg Egan's The Clockwork Rocket introduced readers to an exotic universe where the laws of physics are very different from our own, where the speed of light varies in ways Einstein would never allow, and where intelligent life has evolved in unique and fascinating ways. Now Egan continues his epic tale of alien beings embarked on a desperate voyage to save their world . . . . The generation ship Peerless is in search of advanced technology capable of sparing their home planet from imminent destruction. In theory, the ship is traveling fast enough that it can traverse the cosmos for generations-and still return home only a few years after they departed. But a critical fuel shortage threatens to cut their urgent voyage short, even as a population explosion stretches the ship's life-support capacity to its limits. When the astronomer Tamara discovers the Object, a meteor whose trajectory will bring it within range of the Peerless, she sees a risky solution to the fuel crisis. Meanwhile, the biologist Carlo searches for a better way to control fertility, despite the traditions and prejudices of their society. As the scientists clash with the ship's leaders, they find themselves caught up in two equally dangerous revolutions: one in the sexual roles of their species, the other in their very understanding of the nature of matter and energy. The Eternal Flame lights up the mind with dazzling new frontiers of physics and biology, as only Greg Egan could imagine them.

As the threat of imminent annihilation hangs over the world, so Yalda sets off on a historic rescue mission - one that will take millennia ...

In Yalda's universe, light has no universal speed and its creation generates energy. On Yalda's world, plants make food by emitting their own light into the dark night sky. As a child Yalda witnesses one of a series of strange meteors, the Hurtlers, that is entering the planetary system at an immense, unprecedented speed. It becomes apparent that her world is in imminent danger--and that the task of dealing with the Hurtlers will require knowledge and technology far beyond anything her civilization has yet achieved. Only one solution seems tenable: if a spacecraft can be sent on a journey at suffi ciently high speed, its trip will last many generations for those on board, but it will return after just a few years have passed at home. The travelers will have a chance to discover the science their planet urgently needs, and bring it back in time to avert disaster. Orthogonal is the story of Yalda and her descendants, trying to survive the perils of their long mission and carve out meaningful lives for themselves, while the threat of annihilation hangs over the world they left behind.

Nasim is a young computer scientist, hoping to work on the Human Connectome Project: a plan to map every neural connection in the human brain. But funding for the project is cancelled, and Nasim ends up devoting her career to Zendegi, a computerised virtual world used by millions of people.Fifteen years later, a revived Connectome Project has published a map of the brain. Zendegi is facing fierce competition from its rivals, and Nasim decides to exploit the map to fill the virtual world with better Proxies: the bit-players that bring its crowd scenes to life. As controversy rages over the nature and rights of the Proxies, a friend with terminal cancer begs Nasim to make a Proxy of him, so some part of him will survive to help raise his orphaned son.
