In a chance encounter with a sinister truck driver tricked out like a rhinestone-cowboy, Odd has a vision of an outrageous multiple homicide, the murder of three innocent children, that has not yet been committed. Across California, into Nevada, and back again, Odd desperately gives chase. Along the way, he meets - and charms - a collection of eccentrics who become his allies in a terrifying battle against a sociopath of singular boldness and cleverness - and a shadowy network of like-minded murders whose identities and motivations are mysterious and whose resources seem almost supernatural.
