Summer's finally here, and Derek Fallon is looking
forward to pelting the UPS truck with water balloons, climbing onto the garage roof, and conducting investigations. But when his parents decide to send Derek to Learning Camp, his dreams of fun come to an end. Ever since he's been labeled a "reluctant reader," his mom has pushed him to read real books- something other than Calvin and Hobbes.
As Derek forges unexpected friendships and uncovers a family secret involving himself (in diapers, no less!), he realizes that surprising discoveries and adventures are around the corner, complete with curveballs.
