Her home is in an abandoned mailbox, and she'd rather stay put. Outside kids scream and soccer balls collide, trees look like monsters, and rain is noisy in a scary kind of way. It's much nicer to stay inside, drawing. But then a young boy drops a letter in Willow's mailbox: it's a note to the moon asking for a special favor. Willow knows that if she doesn't brave the world outside, the letter will never be delivered, and the boy will be heartbroken. Should she try? Can she?
