There cannot be many novels in which the central characters travel in time
by exploiting a version of quantum theory invented and published in the physics
literature by the novel鈥檚 author. In Einstein鈥檚 Bridge, physicist John Cramer
tells a delightful tale of wormholes, bubble universes and genocidal
extraterrestrials. Published by Avon, $3.99, ISBN 0380788314.
