Sam, 12, is in trouble: his entire "Pathfinder" scout troop picks on him - and worse. The leader, Peter, is the worst of all. He seems to find a sadistic pleasure in humiliating Sam. This year's trip is to a woods near the French border where a curious legend named Kai is said, around the campfire, to make mischief. But when Sam finds that Kai is no legend and that he makes more than mischief, no one believes him.—Anonymous
