Query: An entertaining circus story

I've actually read this book twice--once because some friends recommended it, and then a few years later I read it again when the movie came out. I thought the story was fascinating about a young man whose veterinary education is interrupted and he hops a circus train. He becomes the circus vet and his whole life changes. Of course this all happens during the Great Depression. I guess I liked this book because of the background research by the author about circuses during that period. The old photos were charming as well. Like another reviewer mentioned not all of the facts regarding the care of animals may have been accurate but it's a fictional story and I think you have to give some license to that. It's a book you would take on the plane or to the beach just to enjoy!
