A group of young friends plants an oak tree, and through the years, they watch it grow. "This is the tree, this is the tree, this is the tree we planted. Hey, there's a nest, that rests in the tree we planted." In a cumulative text much like "This Is the House That Jack Built," the growing children notice new wildlife making homes there—more than just a tree, it's a whole ecosystem. Alison Friend paints friendly yet realistically detailed animals in Kate McMullan's joyful tale for readers 5 to 7.
