Ivan wanted to be free but he was stuck in a cage in a strip mall zoo. So, he painted a mural that communicated his dreams to Julia, who then helped him get moved to a more animal-friendly zoo.
I LOVED this book! I've read it twice and enjoyed it both times because I think the author does an amazing job of showing what Ivan is thinking and feeling. It's done in very short chapters and I thought this was a particularly effective way of telling the story.
