So good that he’s recruited by a group of kids determined to game the system at the biggest theme park in the world—and win the grand prize. Soon Charlie is caught up in the excitement and thrill of using his math skills for awesomeness…but what’s at stake may be more than he’s willing to risk. How far will Charlie go for a chance at the ultimate reward?
