For fans of Book Scavenger, a smart and funny math camp middle-grade mystery with built-in logic puzzles that readers can solve

Twelve-year-old painter Esther can't wait to attend Camp Vermeer, the most prestigious art camp around. But when her stepdad accidentally drives up the wrong mountain, she lands at Camp Archimedes -- a math camp! Determined to prove herself to the other campers, she tackles a brain-teaser that's supposed to be impossible, and solves it in a single day. But not everyone is happy about it... someone wants her out of camp at any cost, and starts leaving cryptic, threatening notes all over the grounds. Esther doesn't know who to trust. Will she solve this riddle before it's too late?

Featuring tricky logic puzzles readers can solve along with the characters and starring a unique, smart, and crafty young heroine, this story has just the right mix of mystery, humor, wit, and heart.
