Widely regarded as the essential book for every science-fiction fan, The Mammoth Book of Best New SF 17 continues to uphold its standard of excellence with more than two dozen stories from the previous year. This year's volume includes not just a host of established masters but also many bright, young talents of science fiction. It embraces every aspect of the genre - soft, hard, cyberpunk, cyber noir, anthropological, military and adventure. Plus the usual thorough summations of the year and a recommended reading list.

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."

This anthology showcases the most exceptional science fiction stories written by women in recent decades, from classic stars like Ursula K. Le Guin and James Tiptree Jr. to science-fiction greats such Nancy Kress, Lois McMaster Bujold, and Karen Joy Fowler to new award-winning talents.

In the new millennium, what secrets lay beyond the far reaches of the universe? What mysteries belie the truths we once held to be self evident? The world of science fiction has long been a porthole into the realities of tomorrow, blurring the line between life and art. Now, in The Year's Best Science Fiction: Twenty-Ninth Annual Collection the very best SF authors explore ideas of a new world. This venerable collection brings together short stories from award winning authors and masters of the field such as Robert Reed, Alastair Reynolds, Damien Broderick, Elizabeth Bear, Paul McAuley and John Barnes. And with an extensive recommended reading guide and a summation of the year in science fiction, this annual compilation has become the definitive must-read anthology for all science fiction fans and readers interested in breaking into the genre.

This thought-provoking collection not only takes us into the past and the future, but also explores what might happen if we attempt to manipulate time to our own advantage. These stories show what happen once you start to meddle with time and the paradoxes that might arise. It also raises questions about whether we understand time, and how we perceive it. Once we move outside the present day, can we ever return or do we move into an alternate world? What happens if our meddling with Nature leads to time flowing backwards, or slowing down or stopping all together? Or if we get trapped in a constant loop from which we can never escape. Is the past and future immutable or will we ever be able to escape the inevitable? These are just some of the questions that are raised in these challenging, exciting and sometimes amusing stories by Kage Baker, Simon Clark, Fritz Leiber, Christopher Priest, Kristine Kathryn Rusch, Robert Silverberg, Michael Swanwick, John Varley and many others.

After Arthur Conan Doyle created the detective, Sherlock Holmes, many writers borrowed him to be the hero of their stories. The anthology offers a selection, old and new.

Ten of the finest short science fiction novels of the 1940s are collected in this outsized volume.
