Zack Freeman is ready to tell his story--the story of a brave young boy and his crazy runaway butt, the story of a crack butt-fighting unit called the B-team, a legendary Butt Hunter and his formidable daughter, and some of the biggest, ugliest and meanest butts ever to roam the face of Earth. Courage and endurance take Zack on a journey across the Great Windy Desert, through the Brown Forest and over a Sea of Butts before descending into the heart of an explosive buttcano to confront the biggest, ugliest and meanest butt of them all!
