Luke Rivers is a part-time bartender and full-time gambler who dreams of scoring big at the dog races. He travels the greyhound circuit with his wife, Jenny, and their young son, Jake, until one morning he wakes up in a motel in Rapid City, South Dakota, to discover that Jenny has left him and taken Jake with her. Now, for the first time, Luke must confront himself--both the tragic family past that led him to gambling and the uncertain future that lies ahead--while coping with a bewildering present. "The Greyhound God is the account of River's anguished search for understanding and purpose. Morris evokes with deft intelligence the colorful world of dog racing and the characters, human and canine, who inhabit it. But this is merely a background for the travails of Luke and his little family, the cheap motels and dusty dreams, the tensions between Luke's tender love for his son and his obsession with his betting "system." Luke's dilemma--whether to pursue Jenny or to continue his gambling life--is complicated further by the presence of a beautiful, sympathetic woman he meets after Jenny leaves, by his painful memories, and by a seemingly miraculous winning streak at the track.
