You have probably seen advertisements for the movie Water for Elephants. It has received a lot of hype recently because it stars Robert Pattinson, but before it was a movie it was a book by Sarah Gruen. A book about love, retirement homes, but most of all the circus.
I loved the setting, the Great Depression was perfect for this kind of book. I love the circus. I have actually never been to a circus and this book painted those pictures beautifully for me. I love seeing the circus from all different angles, seeing how the performers versus the grunt workers lived.
