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: "e;A Perpetual War Fought Within a Cosmic String"e;, "e;A Weapon That Could Destroy the Universe"e;, "e;A Machine That Detects Alternate Worlds and Creates a Choice of Christs"e;, "e;An Immortal Dead Man Sent To The End of the Universe"e;, "e;Murder in Virtual Reality"e;, "e;A Spaceship So Large That There is An Entire Planetary System Within It"e;, and "e;An Analytical Engine At The End of Time"e;, and "e;Encountering the Untouchable."e;
