In “The Days of Perky Pat,” people spend their time playing with dolls who manage to live an idyllic life no longer available to the Earth’s real inhabitants. “Adjustment Team” looks at the fate of a man who by mistake has stepped out of his own time. In “Autofac,” one community must battle benign machines to take back control of their lives. And in “I Hope I Shall Arrive Soon,” we follow the story of one man whose very reality may be nothing more than a nightmare. The collection also includes such classic stories as “The Minority Report,” the basis for the Steven Spielberg movie, and “We Can Remember It for You Wholesale,” the basis for the film Total Recall. With an introduction by Jonathan Lethem, Selected Stories of Philip K. Dick is a magnificent distillation of one of American literature’s most searching imaginations.
