Since being expelled for giving the Greenfield Middle School student body an "explosive" case of food poisoning and sent to live with his father, Spencer Pendleton hasn't exactly been doing his best to put the past behind him and settle into his new life. What with losing the girl-of-his-dreams, Sully, and gaining a there-but-still-absentee father, his life still has a few kinks to work out. And when his single-minded quest to track down the Tribe and reunite with Sully lands him at camp New Leaf, Spencer is convinced things can't get much worse. WRONG! Not only is Camp New Leaf no ordinary camp, but it appears that the Tribe hasn't laid the past to rest, either. And what better place to catch up with an old member-or recruit a few new ones-than a secluded camp for "troubled" boys. With rebellion in the air, Spencer must find a way to stop the Tribe's plans to put down roots and expand its ranks before someone gets seriously hurt-or worse.
