For his many devoted readers, Philip K. Dick is not only one of the "one of the most valiant psychological explorers of the 20th century" (The New York Times) but a source of divine revelation. In the riveting style that won accolades for The Adversary, Emmanuel Carrère follows Dick"s strange odyssey from his traumatic beginnings in 1928, when his twin sister died in infancy, to his lonely end in 1982, beset by mystical visions of swirling pink light, three-eyedinvaders, and messages from the Roman Empire. Drawing on interviews as well as unpublished sources, he vividly conjures the spirit of this restless observer of American postwar malaise who subverted the materials of science fiction--parallel universes, intricate time loops, collective delusions--to create classic works of contemporary anxiety.
