Wyatt and his sister Adeline are determined to investigate an extinct volcano hundreds of miles from home that Adeline believes to be related to their mother's mysterious disappearance. At first it seems like an impossible mission until they realize there's a summer camp conveniently situated near the base of the volcano. So it's off to summer camp for Wyatt, Adeline, and their buddies Beto and Nara. But when they get there, they find it impossible to sneak away from the heavily chaperoned grounds. Opportunity presents itself by way of the Magma Cup, the camp's tournament-style series of mental and physical competitions where the finalists compete in an overnight-and less chaperoned-scavenger hunt on the volcano itself!
