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.
