In the world of cards, each one has a special job to do. Little Card is going to school to become a birthday card—in other words, to sing, play games, and be happy. But on the day he's supposed to take his talents into the world, Long Card tells him there's been a mix-up and they need to trade jobs. How can Little Card bring his exuberance into a library, a quiet place of rules and hushing? This ode to libraries for readers 4 to 8 features Anna Raff's joyful illustrations, which make use of pen, ink, pencil, and collage elements.
