Query: This is a fascinating story!

Tornado is about a man named Pete who is telling a story during a tornado. He is telling a little boy that he had a dog named Tornado when he was younger. Pete discovered the dog in a doghouse when the tornado just ended, so he named him Tornado. During the book Tornado the dog can do card tricks and do some pretty exciting things. I liked this book because, for one thing, I love dogs. Also because I like watching and reading about tornados. What I disliked was that it wasn't very challenging. But overall, it was a very entertaining book!
