Klaus the mouse is always hungry but nothing he eats seems to satisfy him. That is, until he stumbles across a bookstore and starts to nimble some pages of a book! For the first time he feels full... full of stories! The bookseller and the mouse make a pact: she will read him stories and he will help her in the bookstore. After hearing one particular tale, Klaus gets an idea that will fill the store with girls and boys and mice, all hungry for stories.
