"Let's build a tree fort," Russell says to his dad when they move into a house with a big maple tree in the backyard. His dad doesn't know much about building, but he gamely follows Russell's plan. Several trips to the lumber store later, the tree fort is done. There is no slide, balcony or skylight like Russell imagined, but it is perfect--right up until he notices another tree fort going up three houses over."-- Provided by publisher.
