I like The One And Only Ivan. It is about a gorilla and elephants who are in a circus, and Ivan is the main character. He is the headliner of the circus too. It had some sad parts that I didn't like, but I did enjoy the happy parts. I recommend this book to any one who like talking animals, funny things and love -- just know there are some really sad parts. Overall, I enjoyed this book. In the book, the main characters are Ivan, Stella, and Ruby. It is a nonfiction story. Check out more by reading The One And Only Ivan and watching the movie.
