Celebrating ten years of a beloved classic: the New York Times best-selling ode to that wonderful place, the library. Miss Merriweather, the head librarian, is very particular about rules in the library. No running allowed. And you must be quiet. As long as you follow the rules, you are permitted to enjoy the library. There are no rules about lions in a library, and why would there be? But one day, a lion walks into Miss Merriweather's library, and no one is sure what to do. It turns out that the lion seems very well suited for the library. His big feet are quiet on the library floor. He makes a comfy backrest for the children at story hour. And he never roars in the library--at least not anymore. But when something terrible happens, the lion helps in the only way he knows how. Could there ever be a good reason to break the rules? Even in the library?
