Something exciting has been happening in modern SF. After decades of confusion, many of the field's best writers have been returning to the subgenre called, roughly, "hard SF"-science fiction focused on science and technology, often with strong adventure plots. Now, World Fantasy Award-winning editors David G. Hartwell and Kathryn Cramer present an immense, authoritative anthology that maps the development and modern-day resurgence of this form, argues for its special virtues and present preeminence-and entertains us with some spectacular storytelling along the way. Included are major stories by contemporary and classic names such as Poul Anderson, Stephen Baxter, Gregory Benford, Ben Bova, David Brin, Arthur C. Clarke, Hal Clement, Greg Egan, Joe Haldeman, Nancy Kress, Paul McAuley, Frederik Pohl, Alastair Reynolds, Kim Stanley Robinson, Robert J. Sawyer, Karl Schroeder, Charles Sheffield, Brian Stableford, Allen Steele, Bruce Sterling, Michael Swanwick, and Vernor Vinge. "The Hard SF Renaissance" will be an anthology that SF readers return to for years to come.
