Mystery on Pine Lake: Cooper and Packrat (Cooper and Packrat, 1)

Cooper thought living at a campground would be cool. But ever since his parents bought the lakeside campground, he s had more chores and less time to explore. And as if babysitting his little sister and cleaning the bathrooms weren't bad enough, his ex-friend Roy has chosen him as this summer s bullying target. Cooper s only bright spot this summer is his new friend, Packrat, a guy who carries the world in his coat pockets and leaves his troubles behind. But trouble has come to the Wilder Family Campground and Pine Lake, where a family of loons is building a nest. First, someone dams up the lake and floods the nest. Then, when Cooper and Packrat build a raft where the loons can make a new nest, it gets destroyed by someone with big footprints. It s up to the boys to figure out who, why, and how to stop the culprit before it s too late.
