Mailboxes are, at their best, vehicles for letters and packages and other fun deliveries -- and kids learn this early on. But when all that comes is junk, or nothing at all, how does a kiddo get mail? In a stroke of brilliance, the main character of Ben Clanton's It came in the Mail -- Liam, cleverly -- realizes that to get something, maybe he should write a letter. But to whom? And to say what? These questions kick off a postal adventure in which mail becomes magical!
