Change the pastãand the future may come undone. An outstanding collection of time-traveling alternate history stories from 16 major science fiction writers, both old and new. Every day, a thousand possible futures die unborn around us-corners not turned, paths not taken. But if one could go back into the past and change it, the outcome could be unimaginable. _Aristotle and the GunÓ by L.
