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."

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

Dieselpunk: an emerging retro-futuristic sub-genre, similar to steampunk, based on the era between the First World War and the start of the Atomic Age, merging elements of noir, pulp, and the past with today’s technology . . . and sometimes a dash of the occult. Award-winning editor Wallace presents a cutting-edge collection of twenty-five vibrant stories that explore the possibilities of history while sweeping readers into high-powered hydrocarbon-fuelled adventures. Join us in an era when engines were huge, fuel was cheap and plentiful, and steel and chrome blended with the grit and grease of modern machines. Praise for The Mammoth Book of Steampunk: 'World Fantasy Award-winning editor Wallace has compiled an outstanding anthology . . . sure to satisfy even the most jaded steampunk fans and engage newcomers and skeptics. Each story exemplifies steampunk’s knack for critiquing both the past and the present, in a superb anthology that demands rereading.' Publishers Weekly

The Golden Age of Science Fiction, from the early 1940s through the 1950s, saw an explosion of talent in SF writing, including authors such as Isaac Asimov, Robert A. Heinlein, and Arthur C. Clarke. Their writing helped science fiction gain wide public attention, and left a lasting impression upon society. The same writers formed the mold for the next three decades of science fiction, and much of their writing remains as fresh today as it was then.
