**#1 NEW YORK TIMES BESTSELLER *Past midnight, Chyna Shepard, twenty-six, gazes out a moonlit window, unable to sleep on her first night in the Napa Valley home of her best friend's family. Instinct proves reliable. A murderous sociopath, Edgler Foreman Vess, has entered the house, intent on killing everyone inside. A self-proclaimed "homicidal adventurer," Vess lives only to satisfy all appetites as they arise, to immerse himself in sensation, to live without fear, remorse, or limits, to live with intensity *. Chyna is trapped in his deadly orbit. Chyna is a survivor, toughened by a lifelong struggle for safety and self-respect. Now she will be tested as never before. At first her sole aim is to get out alive--until, by chance, she learns the identity of Vess's next intended victim, a faraway innocent only she can save. Driven by a newly discovered thirst for meaning beyond mere self-preservation, Chyna musters every inner resource she has to save an endangered girl . . . as moment by moment, the terrifying threat of Edgler Foreman Vess intensifies.
