This story begs to be read aloud, something I noticed before I knew that's exactly what it was written for. If you do choose to use it for a performance though, pick your audience carefully. It's not a happy book.
Side note: It lost half a star for the illustrations. They're well done and they fit the story, but I just don't love the style. However, that's purely personal preference and not something anyone else should take away as a mark against this book.
