After graduating from college, Lori returns home only to lose her parents in a fire. In the wake of this tragedy, unusual events begin to unfold, starting with the discovery of a girl named Priscilla Fairmount in an old high school yearbook who looks just like Lori. But the yearbook is from before Lori was born! Now, suspected by the police for being involved in the fire, Lori begins a descent into madness, convinced that her "twin," Priscilla, is attempting to take over her mind... unaware of the brutal role she herself may be playing in the events which now shape her fate. From Robert Bloch, the master of American horror, Lori is a cerebral and terrifying read.
