Dude, Where's My Saxophone?

Summer is here, and Zac Wiles and the Benton Bluff Junior High band are headed to band camp. But as soon as they arrive, things start disappearing. First it's music, then it's Zac's saxophone. As the band's resident class clown, Zac's antics always earn a few eye rolls. But now, he's being called a thief! Can Zac find the culprit and prove he'd never take his jokes that far?
