"We have a three-strikes-and-you're-out policy here. You now have two strikes." Mark Prescott is not having a fun time at summer camp. First of all, he went there so he could talk with his best friend, Patti. But she only wants to discuss her new boyfriend. Then Mark finds he's sharing a cabin with Joe Devlin, Odyssey's biggest bully, who gets Mark into trouble with the camp's leaders. Mark grows irritated by the unfairness of his situation and Joe's obnoxious behavior. Yet Mark feels there must be some hidden reason Joe has become expecially bad. Finally, Mark and Joe find themselves paired in a treasure hunt that puts them in unexpected danger. Through his adventures in camp, Mark learns valuable lessons about friendship and how God uses one person to help another.
