The Clubhouse (Penguin Young Readers, L3)

When Peter, Archie, and Louie see the pile of wood, they think it's just a big mess. After all, it's just a pile of old junk sitting by a fence. But when Amy and Lily look at it, they see a clubhouse that's waiting to be built. Louie's father says that one man's trash is another man's treasure. Is he right?
