Stanley, Heston, Julius, and Floyd don't have anywhere to hang out this summer. They need a place to perform science experiments, play superheroes, paint pictures, and camp out without being bothered by parents and little sisters. A clubhouse would be perfect. They all pitch in to build one. But the four friends soon realize that each has a different idea of what the perfect clubhouse should be-which threatens both the project and their friendship.
Mahoney's playful illustrations highlight this humorous tale of four individuals who find out that having fun together is what really makes something perfect.
