This companion to the Edgar Award nominee MOXIE AND THE ART OF RULE BREAKING, which SLJ called “a breathless thrill ride,” features hidden pirate treasure and a high-stakes game of tag – just what you’d expect from summer camp!  While at Wilderness camp on the Boston Harbor Islands, Ollie must navigate new friends, new enemies, and a high-stakes game of tag, so the last thing he needs is a mystery. But then Ollie meets Grey, an elusive girl with knowledge of the island’s secrets, including the legend of a lost pirate treasure, which may not be a legend after all. The sidekick steps into the spotlight as Ollie uses his wits and geocaching skills to keep long-lost treasure out of the wrong hands in this exciting adventure-mystery from fan-favorite middle grade author Erin Dionne.
