Ollie and the Science of Treasure Hunting

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.
