Cooper thought living at a campground would be cool. But trouble has come to the Wilder Family Campground and Pine Lake, where a family of loons is trying to build a nest. Someone is out to harm the loons. Is it the bully with a chip on his shoulder? The irritable camper with a shady past? Or the publicity-seeking reporter? It's up to Cooper and new friend Packrat to figure out who, why, and how to stop the culprit before it's too late.
