Children Make Terrible Pets by Peter Brown
At heart, this is a pretty basic story: a little girl wants to keep an animal she found as a pet. Any number of books and television shows have told this same story. What gives this book extra appeal is its subversion of the character roles. Our main character, Lucy, is a bear. The animal that she finds and names, Squeaker, is a human child. It is terribly silly but a great deal of fun. Lucy's voice is fantastic and Brown's illustrations are incredibly expressive. The first time I read this book to a group of kids, they demanded and immediate reread.
