Milo and his friend Melba are bookworms. They live in a book on a shelf in Peter's room. It's an old book that hasn't been taken down in many years. Milo likes nothing better than to eat his way through a book. He especially likes long words, words with fancy writing, and bookmarks with pictures of flowers. One day he makes a decision. He would see the world. He would go west, and Melba would go east. But the world is scary. So he goes back home and eats his way to page 18 where he finds Melba asleep on the binding. Being very tired and very full, he opens his mouth in a huge yawn and falls asleep on the word Whisper.
