Big time adventure awaits the Beacon Street Girls and the rest of their seventh-grade class. The seventh-grade class is heading to Lake Rescue in Vermont for their big overnight trip. How cool!

Will the physical challenges of this outdoor adventure prove too challenging for one overweight seventh-grade girl?
