Zach Carson is a loyal friend. But is loyalty enough to keep best friends together when one of them sets fire to the rural barn they use as the local hangout? Zach, Jeff Barsell and Arnie Wilson struggle to pick up the pieces when news spreads that a body was discovered in the burnt out shell of the neighbouring home. When the word murder is used by the local police, the stakes grow even higher. When the police start searching for their most likely suspect-none other than Jeff's older brother, and nemesis, Marty Barsell-the boys decide to join forces and come up with a way to prove his innocence. But just how innocent is Marty Barsell? When Marty admits to being at the scene of the crime, the three friends enlist the help of Zach's annoying sister, Sherry, as well as the sympathetic town eccentric, Ms. Halverton. But can they keep it together long enough to save Marty, and themselves, from imminent catastrophe? Summer on Fire is the story of friendships, and the lines we are asked to cross in order to keep them.
