Sobre o livro
When a lion visits the library, no one knows what to do: there are no rules about lions in the library. But soon he's indispensable - "What a helpful lion," people say. "How did we ever get along without him?" But one day the head librarian falls and breaks her arm, and the only way the lion can get help is to roar. And that is breaking the rules.
