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.

Paul Durham keeps making Copies of himself: software simulations of his own brain and body which can be run in virtual reality, albeit seventeen times more slowly than real time. He wants them to be his guinea pigs for a set of experiments about the nature of artificial intelligence, time, and causality, but they keep changing their mind and baling out on him, shutting themselves down. Maria Deluca is an Autoverse addict; she’s unemployed and running out of money, but she can’t stop wasting her time playing around with the cellular automaton known as the Autoverse, a virtual world that follows a simple set of mathematical rules as its “laws of physics”. Paul makes Maria a very strange offer: he asks her to design a seed for an entire virtual biosphere able to exist inside the Autoverse, modelled right down to the molecular level. The job will pay well, and will allow her to indulge her obsession. There has to be a catch, though, because such a seed would be useless without a simulation of the Autoverse large enough to allow the resulting biosphere to grow and flourish — a feat far beyond the capacity of all the computers in the world.

Andrew Worth is a science journalist with optic nerve taps and a gut full of memory chips. Burnt out after completing a documentary on controversial developments in biotechnology, he turns down a chance to report on a baffling new mental disorder known as Distress and instead takes an assignment covering the Einstein Centenary Conference on the artificial island of Stateless. There, a young South African physicist, Violet Mosala, is expected to unveil her candidate for a Theory of Everything. But the assignment is not the tropical respite Worth was expecting. While the politics surrounding the creation of Stateless grows more turbulent, and ignorance cults stage protests against the gathering scientists, a secretive group known as the Anthrocosmologists, with some very strange ideas about the Theory of Everything, begin to enact their own agenda.

In the 30th century, most people have chosen immortality, joining the polises to become conscious software. Others have opted for robot bodies, while some holdouts remain "fleshers." And then there''s the Orphan, a genderless digital being grown from a mind seed. It''s up to the Orphan and a group of refugees to find the knowledge that will save inhabitants from extinction.

Collected together here for the first time are twelve stories by the incomparable Greg Egan, one of the most exciting writers of science fiction working today. In these dozen glimpses into the future Egan continues to explore the essence of what it is to be human, and the nature of what - and who - we are, in stories that range from parables of contemporary human conflict and ambition to far-future tales of our immortal descendants. Return to the universe of the meta-civilisation known as the Amalgam, which Egan explored in his critically acclaimed novel Incandescence: ''Riding the Crocodile'', which recounts an epic endeavour a million years from now to bridge the divide between the Amalgam and the reclusive Aloof; ''Glory'', set in the same future, in which two archaeologists strive to decipher the artefacts of an ancient civilisation, and ''Hot Rock'', where an obscure, sunless world conceals mind-spinning technological marvels, bitter factional struggles, and a many-layered secret history. This superb collection also includes the title story, the Hugo Award-winning ''Oceanic'': a boy is inducted into a religion that becomes the centre of his life, but as an adult he must face evidence that casts a new light on his faith.

In a world where the cells that make up our bodies are not committed to any one organism, Marla is confronted by the fickleness of her cytes, and resolves to understand them with help from Ada, a centuries-old Flourisher. Swappers like Ruth embrace fluidity, and meet with others to exchange cytes, seeking the perfect mix. But Ruth faces her own crisis, and as the technology to manipulate cytes advances, all three are drawn into a struggle to shape the future of life.

Set in a near future Iran (where the theocracy has been overthrown, but where Muslim religion still dominates the culture), an Arab/Muslim focused MMORG gaming companies cutting edge AI software might hold the key achieving "uploaded consciousness." Martin is an Australian journalist who covered uprising and overthrow of the Iranian theocracy, and has since “gone native” with a Iranian wife and child. As tragedy strikes his multi-cultural family, Martin struggles to maintain his place in his adapted culture, and to provide for his child. Zendigi explores what it means to be human, and the lengths one will go to in order to provide for ones children. This emotional roller coaster explores a non-Western-European near future that both challenges ideas of global mono-culture and emphasizes the humanity we all share.

When electronics importer Cara Leon goes missing, private investigator Sam Mujrif is hired by her sister to investigate. Cara is eight times taller than Sam, but evidence soon points to players much smaller than either of them. As Sam and his cross-scale colleagues pursue the case, it becomes apparent that Cara’s disappearance is linked to the development of technology with the potential to reshape their whole society, and radically alter the balance of power between the scales.

When a detective, a new mother, is assigned to the case of a horrific triple murder, it appears to be a self-contained domestic tragedy, a terrible event but something that doesn’t affect the rest of the community. But it slowly becomes clear that something much darker may be at play, something that spreads out from the scene of the crime to corrode the closest relationships of everyone it touches, in Greg Egan''s The Nearest, a Tor.com Original.

Welcome to Teranesia, the island of butterflies, where evolution has stopped making sense. Prabir Suresh lives in paradise, a nine-year-old boy with an island all his own: to name, to explore, and to populate with imaginary creatures stranger than any exotic tropical wildlife. Teranesia is his kingdom, shared only with his biologist parents and baby sister Madhusree. The evolutionary puzzle of the island’s butterflies that brought his family to the remote South Moluccas barely touches Prabir; his own life revolves around the beaches, the jungle, and the schooling and friendships made possible by the net. When civil war breaks out across Indonesia, this paradise comes to a violent end. The mystery of the butterflies remains unsolved, but nearly twenty years later reports begin to appear of strange new species of plants and animals being found throughout the region — species separated from their known cousins by recent, dramatic mutations that seem far too useful to have arisen by chance from pollution, disease, or any other random catastrophe. Madhusree is now a biology student, proud of her parents’ unacknowledged work, and with no memories of the trauma of the war to discourage her, she decides to join a multinational expedition being mounted to investigate the new phenomenon. Unable to cast off his fears for her safety, Prabir reluctantly follows her. But travel between the scattered islands is difficult, and Madhusree has covered her tracks. In the hope of finding her, Prabir joins up with an independent scientist, Martha Grant, who has come to search for both clues to the mystery and whatever commercial benefits it might bring to her sponsor. As Prabir and Martha begin to untangle the secret of Teranesia, Prabir is forced to confront his past, and to face the painful realities that have shaped his life.

The long-awaited new novel from Greg Egan! Hugo Award-winning author Egan returns to the field with Incandescence, a new novel of hard SF. The Amalgam spans nearly the entire galaxy, and is composed of innumerable beings from a wild variety of races, some human or near it, some entirely other. The one place that they cannot go is the bulge, the bright, hot center of the galaxy. There dwell the Aloof, who for millions of years have deflected any and all attempts to communicate with or visit them. So when Rakesh is offered an opportunity to travel within their sphere, in search of a lost race, he cannot turn it down. Roi is a member of that lost race, which is not only lost to the Amalgam, but lost to itself. In their world, there is but toil, and history and science are luxuries that they can ill afford. Rakesh''s journey will take him across millennia and light years. Roi''s will take her across vistas of learning and discovery just as vast.

In an alien universe where space and time play by different rules, interstellar voyages last longer for the travellers than for those they left behind. After six generations in flight, the inhabitants of the mountain-sized spacecraft the Peerless have used their borrowed time to develop advanced technology that could save their home world from annihilation. But not every traveller feels allegiance to a world they have never seen, and 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 of the crew welcome the opportunity to be warned of impending dangers - and perhaps even hear reports of the ship''s triumphant return - others are convinced that knowing what lies ahead will be oppressive, and that the system will be abused. Agata longs for a chance to hear a message from the ancestors back on the home world, proving that the sacrifices of the travellers have not been in vain, but her most outspoken rival, Ramiro, fears that the system will undermine every decision the travellers make. When a vote fails to settle the matter and dissent erupts into violence, Ramiro, Agata and their allies must seek a new way to bring peace to the Peerless - by traveling to a world where time runs in reverse. The Arrows of Time is the final volume of the Orthogonal trilogy, bringing a powerful and surprising conclusion to the epic story of the Peerless that began with The Clockwork Rocket and The Eternal Flame.

Une belle nuit, il y a trente-trois ans, les étoiles ont disparu. La Terre et avec elle l''humanité se retrouvent isolées dans une Bulle cosmique centrée sur le soleil, placées en quarantaine. Pourquoi ? Par qui ? Les hypothèses dégénèrent en cultes religieux insolites et souvent malsains. Et dans le même temps, l''humanité a appris à vivre dans les mondes virtuels. Ou bien est-ce tout l''univers qui serait devenu virtuel ? La clé du mystère serait-elle détenue par Laura Andrews, trente-trois ans, l''âge exact de la Bulle ? Mais Laura a disparu. Et les Possibles se déchaînent. Un roman quantique, éblouissant, par la grande révélation de ces dernières années, Greg Egan, écrivain australien, dont certains prétendent, puisque personne ne l''a jamais rencontré, qu''il serait un programme informatique, le premier auteur artificiel.

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 At the Publisher''s request, this title is being sold without Digital Rights Management Software (DRM) applied.

From the award-winning author Greg Egan comes a Tor.com Original sci-fi short story, "Zeitgeber" For millions of years, life on Earth has taken its cues from the rising and setting of the sun, and for most of human history we''ve followed the same rhythm. But if that shared connection was broken, and we each fell under the sway of our own private clock, could we still hold our lives together? One family is about to find out.

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.

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.

Immortality, but at what price, in what form, and how could you be you? Find out in Greg Egan''s "Uncanny Valley," a Tor.com Original short story In the near future it’s possible to build a new you, a better you, one that could carry on forever. But if you could carry on, if you could make choices about who you would be forever, how much of your past would you bring with you? Would you be tempted to maybe...edit? Adam isn’t all that he used to be, but he wants to be. At the Publisher''s request, this title is being sold without Digital Rights Management Software (DRM) applied.

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 are entering the planetary system at an immense, unprecedented speed. It becomes apparent that her world is in imminent danger — and 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 sufficiently 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.

For twenty thousand years, every observable phenomenon in the universe has been successfully explained by the Sarumpaet Rules: the laws governing the dynamics of the quantum graphs that underlie all the constituents of matter and the geometric structure of spacetime. Now Cass has stumbled on a set of quantum graphs that might comprise the fundamental particles of an entirely different kind of physics, and she has travelled three hundred and seventy light years to Mimosa Station, a remote experimental facility, in the hope of bringing this tantalising alternative to life. The “novo-vacuum” is predicted to begin decaying the instant it’s created, but even a short-lived, microscopic speck could shed light on the origins of the universe, and test the Sarumpaet Rules more rigorously than ever before. Cass’s experiment turns out to be more successful than anticipated: the novo-vacuum is more stable than the ordinary vacuum around it, and a region in which the new physics holds sway proceeds to expand out from Mimosa at half the speed of light. Six hundred years later, more than two thousand inhabited systems have been lost to the novo-vacuum. On the Rindler, a ship that has matched velocities with the encroaching border, people have come from throughout inhabited space to study the phenomenon. Most are Preservationists, hunting for a way to turn back the tide, but a few belong to another faction: Yielders, who believe that the challenge of adapting to survive on the far side of the border would reinvigorate a civilisation that has grown stale and insular. Tchicaya has come to the Rindler to join the Yielders, but when Mariama — a childhood friend whose example inspired him to abandon his own home world and traditions for a life of travel — arrives soon after, he is shocked to discover that she plans to help the Preservationists find a way to destroy the novo-vacuum. As a theoretical breakthrough leads to a sequence of experiments that begins to reveal the true richness of the world behind the border, tensions between the opposing factions grow. When a splinter group responds to these revelations with violent, unilateral action, Tchicaya and Mariama are forced into an uneasy alliance, and travel together through the border, balancing old and new loyalties against the fate of two incomparably different universes.

In the deep future mankind is barely distinguishable from machine intelligences, rarely embodied outside of virtual environments. It is time, using the very building blocks of time and space, to engineer the universe itself. Time to enter a new quantum realm of marvels and terrors. The new novel from one of the worlds most respected and acclaimed writers marks a dramatic move into a new arena ¿ that of the wide screen SF epic ala Baxter, Banks, Hamilton and Macleod. Novels such as this have proved to be the engine house for both the major sales and the best ideas of modern SF. That the genre¿s primary ideas man and one of its finest prose stylists should direct his energies to this sort of canvas promises much. This will be Greg Egan¿s breakout book.
