What if Gandhi and his army of pacifists faced down the Nazis? What would Philip K. Dick and Richard M. Nixon have said to one another? These and other wild imaginings of events that never occurred make up this prime collection of alternate histories. Written over fifty years, culled from the pages of The Magazine of Fantasy and Science Fiction, these 15 tales enthrall readers drawn to the fantastic, the meta-real, the might-have-been. Contributors include Sci-Fi/Fantasy legends C.M. Kornbluth, Ben Bova, Robert Silverberg, Harry Turtledove, Alfred Bester, and Poul Anderson.
