Greg Egan - Dichronauts
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 - Instantiation

Greg Egan - Phoresis
Welcome to Tvibura and Tviburi, the richly imagined twin planets that stand at the center of Greg Egan’s extraordinary new novella, Phoresis. These two planets - one inhabited, one not - exist in extreme proximity to one another. As the narrative begins, Tvibura, the inhabited planet, faces a grave and imminent threat: the food supply is dwindling, and the conditions necessary for sustaining life are growing more and more erratic. Faced with the prospect of eventual catastrophe, the remarkable women of Tvibura launch a pair of ambitious, long-term initiatives. The first involves an attempt to reanimate the planet’s increasingly dormant ecosphere. The second concerns the building of a literal “bridge between worlds” that will connect Tvibura to its (hopefully) habitable sibling. These initiatives form the core of the narrative, which is divided into three sections and takes place over many generations. The resulting triptych is at once an epic in miniature, a work of hard SF filled with humanist touches, and a compressed, meticulously detailed example of original world building. Most centrally, it is a portrait of people struggling - and sometimes risking everything - to preserve a future they will not live to see. Erudite and entertaining, Phoresis shows us Egan at his formidable best, offering the sort of intense, visionary pleasures only science fiction can provide.
Greg Egan - The Arrows of Time
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.
Greg Egan - The Clockwork Rocket
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. 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.
Greg Egan - Permutation City
The good news is that you have just awakened into Eternal Life. You are going to live forever. Immortality is a reality. A medical miracle? Not exactly. The bad news is that you are a scrap of electronic code. The world you see around you, the you that is seeing it, has been digitized, scanned, and downloaded into a virtual reality program. You are a Copy that knows it is a copy. The good news is that there is a way out. By law, every Copy has the option of terminating itself, and waking up to normal flesh-and-blood life again. The bail-out is on the utilities menu. You pull it down... The bad news is that it doesn't work. Someone has blocked the bail-out option. And you know who did it. You did. The other you. The real you. The one that wants to keep you here forever.
Greg Egan - The Eternal Flame
The generation ship Peerless is suffering from a population explosion, and the only way to reduce the number of children is by drastically limiting the females' food intake. So population control consists of two barbaric choices: starvation, or suicide. Trying to find a better way, a biologist starts experimenting with animals, and stumbles on a technique that radically alters the reproductive cycle. But while the advantages are obvious, there's a major drawback: while it spares women from their old role - reproduction without hope of survival - it will essentially wipe out an entire sex. Amid the turmoil created by this new possibility, physicists on the ship are working to develop the technology they will need to complete the mission of the Peerless. One of the expedition's founders dreamed of discovering the Eternal Flame: a way to generate thrust without consuming any fuel at all. The inhabitants on board the Peerless have some hard choices to make - and the wrong one could spell extinction for their entire race.
Greg Egan - Distress
Investigative reporter Andrew Worth turns down a documentary on a mysterious new mental illness -- "Distress, " or acute clinical anxiety syndrome, for another assignment. He's on his way to the artifical island of Stateless, where the world's top physicists are gathering to decide on a new TOE, or Theory of Everything, to replace Einstein's outmoded legacy. Chief among the scientists is the brilliant African Nobel laureate, Violet Mosala, the focus of Worth's story, who is the subject of mysterious death threats. Worth begins his own investigation, but it takes on even more urgency when he finds that Distress, the mental plague now affecting millions, is linked somehow to the approaching "Aleph Moment" when the TOE is finalized. The countdown has begun for a disaster that will reach all the way back to the Big Bang. And beyond...
Greg Egan - Diaspora
A dramatic insight into the future of Man in the 30th century and beyond where life is divided into three; fleshers - true homo-sapines; Gleisner robots - human minds within machines; and polises - supercomputers teeming with intellgent software containing copies of human personalities.
Greg Egan - Schild's Ladder
The new novel from one of the world's most respected and acclaimed writers marks a dramatic move into a new arena - that of the wide-screen SF epic a la Baxter, Banks, Hamilton and Macleod. Cass has stumbled on something that might be an entirely different type of physics and she's travelled three hundred and fifty light-years to Mimosa Station, a remote experimental facility, to test her theory. The novo-vacuum she creates is predicted to begin decaying the instant it's created, but even so shortt-lived a microscopic speck could shed new light on the origins of the universe. But instead of decaying, Cass's novo-vacuum is wildly successful and begins expanding, slowly but inexorably taking over the universe...
Greg Egan - Oceanic
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.
Greg Egan - Karantén
A huszonegyedik század vége - egy olyan kor, amikor a biomérnöki munkák révén bárki tetszés szerint módosíthatja tudatát; egy éra, amelyet oly roppant méretű információs rendszerek uralnak, hogy titkok gyakorlatilag nem is léteznek. Az ember mindent megszerezhet és elérhet, amit akar, ám ettől még az élete nem lesz kevésbé bizonytalan. Ráadásul harminchárom éve az emberiség a félelem szülte vallási kultuszok és a terrorizmus rettegésében él. Egy éjszaka kialudtak a csillagok; minden eltűnik az égről. A "Buborék" - egy tökéletes gömb, amelynek a Nap a középpontja - izolálta a Naprendszert. Az emberiséget bebörtönözték. Karanténba zárták. Ebben a csodálatos és kiszámíthatatlan korban indítja el a megdöbbentő események láncolatát egy titokzatos eset - Laura Andrews harminckét éves nő, aki egy hat éves gyermek értelmi képességeivel rendelkezik, egy napon eltűnik a jól őrzött Hilgemann Intézetből, a kamerák és biztonsági őrök szeme elől...
Greg Egan - Luminous

Greg Egan - Incandescence
Are you a child of DNA? Composed of innumerable beings from a wide variety of races, human and otherwise, the vast meta-civilization known as the Amalgam spans nearly the entire galaxy–except for the bright, hot center. There dwell the Aloof, silent residents of the galactic core, who for millions of years have deflected all attempts at communication and contact. But when Rakesh encounters a traveler who claims to have been contacted by the Aloof and shown a meteor bearing traces of DNA, he cannot turn down the opportunity to explore uncharted space in search of a lost world. On a translucent world of rock called the Splinter, deep within the sea of light known as the Incandescence, lives Roi, a member of a race lost not only to the Amalgam, but to itself. Her world is in grave danger, and it will take an unprecedented flowering of science to save it. Rakesh's journey will take him across light-years and millennia. Roi's will take her through vistas of learning and discovery just as vast. Greg Egan's blend of dazzling speculation and gripping storytelling will leave you stunned by the wondrous vision of the far future that he has created.
Greg Egan - Perihelion Summer
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.
Greg Egan - Quarantine
It's late in the 21st century and bioengineering has become such a commonplace that people are able to modify their minds in any way they wish. It is an era which has been shaped by information systems so vast that security, in any form, is easily breached. You can be just exactly what you want to be, but the world outside and your life in it aren't going to run any more smoothly... Because one night, thirty three years ago, the stars went out and everything disappeared from the sky. 'The Bubble' - a perfect sphere centred on the sun - made its appearance and isolated the earth from the solar system. Humanity has been cut off ... Quarantined.
Greg Egan - Zendegi
In the near future, journalist Martin Seymour travels to Iran to cover the parliamentary elections. Most would-be opposition candidates are disqualified and the election becomes the non-event the world expects. But shortly afterward a compromising image of a government official captured on a mobile phone triggers a revolutionary movement that overthrows the old theocracy. Nasim Golestani, a young Iranian scientist living in exile in the United States, is hoping to work on the Human Connectome Project - which aims to construct a detailed map of the wiring of the human brain - but when government funding for the project is canceled and a chance comes to return to her homeland, she chooses to head back to Iran. Fifteen years after the revolution, Martin is living in Iran with his wife and young son, while Nasim is in charge of the virtual world known as Zendegi, used by millions of people for entertainment and business. When Zendegi comes under threat from powerful competitors, Nasim draws on her old skills, and data from the now-completed Human Connectome Project, to embark on a program to create more lifelike virtual characters and give the company an unbeatable edge. As controversy grows over the nature and rights of these software characters, tragedy strikes Martin's family. Martin turns to Nasim, seeking a solution that no one else can offer... but Zendegi is about to become a battlefield.
Greg Egan - Teranesia
(from Egan's website) 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.

Greg Egan - Diaszpóra
Íme, az árva! Olyan világba született, amely nem is valódi. Digitális lény, akit elmemagból növesztettek, semleges nemű, virtuális polgár szondák, műholdak és szerverek végtelen hálózatában, mely átszövi az egész Naprendszert a külső bolygóktól a Nap háborgó felszínéig. A XXI. századi Introdus óta az emberiség drasztikus változásokat eszközölt önmagán. A legtöbben a halhatatlanságot választották, csatlakoztak a poliszokhoz, tudatos szoftverekké váltak. Mások a gleiznerlét mellett döntöttek: eldobható, felújítható robottestekbe költözve nem vesztették el a kapcsolatot az erők és a súrlódás fizikai világával. Sokan közülük végleg elhagyták a Naprendszert fúziós meghajtású űrhajóikkal. És vannak, akik a végsőkig kitartanak. Ők a Föld sarában és dzsungeleiben hátramaradt húsvérek: egyesek álommajmokká sorvadtak, mások a tengerben lubickolnak vagy a levegőben repdesnek, a statikusok és a hídverők pedig élhető emberi sorsot próbálnak kovácsolni maguknak. A polgárok gondtalan nyugalmának azonban egy csapásra vége szakad, amikor egy nem várt katasztrófa éri a húsvéreket, mely arra enged következtetni, hogy a poliszok jövőjét a természet törvényeinek fittyet hányó, bizarr asztrofizikai folyamatok fenyegetik. Így hát az árva polgárok és húsvér menekültek egy csoportjával karöltve nyomába ered a tudásnak, amely egyedül szavatolhatja a biztonságukat...
