The STONE Age meets the TEENage Quentin Moss is an average 13-year-old boy with an anything-but-average problem: the cave boy he dreamed about last night has shown up, alive and smelly, in his bedroom. As past and present collide with comic consequences, Quentin must hide the secret identity of his new friend who is fascinated by zippers and loves to flush the toilet - over and over again. Before the day is over, Quentin and his best friend, Buzz, have to find a way to help the homesick cave boy get back to his home - thousands of years in the past. But first they have to get through the school day. Quentin may not be the cutest, smartest guy in school, but the way he deals with the greatest adventure of his life will have readers of all ages laughing out loud.
