Denny Burke is finally about to graduate high school. Senior year has been one bad thing after another: a broken leg, a broken heart, and - worst of all - a broken home. With four of his closest friends, Denny goes on one last rock-climbing trip to prove he's ready to start his adult life... On their trip the five teens receive a genetic boost beyond anything they'd ever imagined. Denny's soon faced with the first big decision of his adult life: does he give up these powers and stay a normal teenager, or does he keep them... and graduate from the human race?
