The owl-tree is not like any tree Joe has ever seen. Its huge & leafy & shivers like a person; it even seems to speak. Granny Diamond once saw an owl perched among its branches & she has loved the tree ever since. It means the world to her. But her neighbour Mr Rock wants to cut it down. Why does he dislike the owl-tree so much? Does it have a secret to tell Joe? & how can he a boy too scared even to climb the tree be the one to save it?
