"Welcome to Barlow, Arkansas, a small town where the simple life is getting very complicated. Hank Harmon would like nothing more than to live out his autumn years in peace and quiet. But a legendary creature from the fringes of folklore strolls in Hank's life and those dreams of peace are shattered. Hank and his friends find themselves squaring off against a vengeful preacher, a sheriff with a grudge, and the Hollywood dream factory. This is a story of love, friendship, and the Sasquatch. This is a story of junk food, fistfights, misdemeanors, and liquor."--Back cover.
