Escape from Camp Cooties — Dan Thompson

Rip Haywire thinks he's got it made. Instead of going to bed early, doing fractions and eating Brussels sprouts, he gets to accompany his soldier-of fortune dad on laughably dangerous international missions. He's the only 12-year-old in the world with a working knowledge of the Seven Most Common Booby Traps Used by Ancient Civilizations to Protect Their Precious Treasures. It sure beats school, right?
            But Rip's life is about to change when his dad, in a sudden fit of responsibility, assigns Rip his toughest mission yet: a historically all-girls summer camp. Will Rip learn how to get along with his feminine camp mates, most of whom have never even seen a flame thrower, let alone used one to fend off a pack of rabid hyenas? Can Rip solve the mysteries that surround the camp and one intriguing girl in particular? Readers will follow Rip's misadventures in his whimsically illustrated journal, helping him to solve puzzles and beat the bad guys, as he learns that friendship can be more valuable than ancient treasure, and more powerful than a well-placed land mine.
