Hugo Award-winning editor Gardner Dozois' annual anthology has long been considered the standard by which other best-of-the-year SF collections are judged. After two decades' worth of superlative science fiction, Dozois now presents a retrospective compilation culling from the last 20 years. Here under one banner is some of the finest work by the genre's leading authors, with a star-studded list of contributors that features among others: Stephen Baxter, Greg Bear, William Gibson, Terry Bisson, Greg Egan, Ursula K. Le Guin, Robert Reed, Robert Silverberg, Bruce Sterling , Charles Stross, Michael Swanwick, Gene Wolfe. A number of the selections are now considered classics. Some notable stories include: 'Blood Music', Greg Bear's Hugo-winning exploration of nanotechnology. 'Bears Discover Fire', Terry Bisson's tongue-in-cheek consideration of future ursine evolution. 'The Left Hand of Darkness', Ursula K. Le Guin's coming-of-age SF tale. 'The Winter Market', in which William Gibson returns to the subject that made him a cultural icon, cyberpunk. With work spanning two decades, this is the most significant science fiction short story anthology published in years.

Here are 25 stories of science fiction that push the envelope, by the biggest names in an emerging new crop of high-tech futuristic SF - including Charles Stross, Robert Reed, Alastair Reynolds, Peter Hamilton and Neal Asher. High-tech SF has made a significant comeback in the last decade, as bestselling authors successfully blend the super-science of 'hard science fiction' with real characters in an understandable scenario. It is perhaps a reflection of how technologically controlled our world is that readers increasingly look for science fiction that considers the fates of mankind as a result of increasing scientific domination. This anthology brings together the most extreme examples of the new high-tech, far-future science fiction, pushing the limits way beyond normal boundaries. The stories include: "A Perpetual War Fought Within a Cosmic String", "A Weapon That Could Destroy the Universe", "A Machine That Detects Alternate Worlds and Creates a Choice of Christs", "An Immortal Dead Man Sent To The End of the Universe", "Murder in Virtual Reality", "A Spaceship So Large That There is An Entire Planetary System Within It", and "An Analytical Engine At The End of Time", and "Encountering the Untouchable."

War is becoming increasingly 'SF-ized' with remotely controlled attack drones and robot warriors already in development and being tested. Over the past 100 years the technology of war has advanced enormously in destructive power, yet also in sophistication so that we no longer seem to live under the constant threat of all-out global thermonuclear cataclysm. So what will future wars be like? And what will start them: religion, politics, resources, refugees, or advanced weaponry itself? Watson and Whates present a gripping anthology of SF stories which explores the gamut of possible future conflicts, including such themes as nuclear war, psychological and cyberwars, enhanced soldiery, mercenaries, terrorism, intelligent robotic war machines, and war with aliens. All the stories in this collection of remarkable quality and diversity reveals humankind pressed to the limits in every conceivable way.
