I loved this book! I had some doubts going into it, but it is really good. It is told in alternating perspectives from a 93 year old man's current life and his life when he was younger. It tales his tale of him losing his parents and hopping on a train that turns out to be a circus train. Since he was studying to be a vet at Cornell University, the owner highers him as their personal vet for the menagerie. I honestly love the old man and his perspective. And I think this book has something for everyone. It's got a bit of romance, adventure, mystery, and deep characters.
