When readers first encounter science fiction, they find adventures on other planets and in future worlds, explorations of future technology and its implications, and extrapolations of social trends and warnings of where they may lead-but they also encounter concepts heretofore undreamed of, and the impact on the readers' thinking does nothing less than turn their world upside down. Now, David Drake, Jim Baen and Eric Flint gather together some of the greatest science fiction ever written in one volume, with each story chosen for a startling breakthrough concept which left readers stunned, and changed the course of science fiction. In the Golden Age of science fiction, the SF magazines weren't given titles such as Astounding, Amazing, Startling, etc., for nothing! Pick up this generous serving of the very best of science fiction and prepared to be astounded, amazed, startled-and entertained.
