Intensity (Hardcover, Turtleback School & Library ed.)

Past midnight, Chyna Shepherd, twenty-six, gazes out a moonlit window, unable to sleep on her first night in the Napa Valley home of her best friend. Instinct proves reliable. A murderous sociopath, Edgar 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 live without fear, remorse, or limits, to live with intensity. And Chyna is the only one left to stop him.
