"Peter is having a birthday party, and he's already asked his pals in the neighborhood to come. But Amy is a special friend--so Peter wants to write her a special invitation. When he rushes out into a thunderstorm to mail it, he runs headlong into trouble. Will she get the letter in time? And will she decide to come?"

Creates a great springboard to talk about misunderstandings, boy and girl friends and awkward social situations. Once again, Keats beautifully illustrates another timeless story.
