Isaac Asimov's Valentines

Robert Silverberg, Terry Bisson, Connie Willis, and seven other masters of science fiction offer imaginative stories that ask such questions as: What constitutes attraction in a world where "chemistry" has taken on a whole new meaning? Does a man's passion distinguish him from machines or turn him into one? What is the future of love? An outstanding collection from the pages of "Asimov's Science Fiction" magazine.
