Is It Really About Elephants?

I want to write briefly about a new book in our collection. The Des Moines Register has shown Water for Elephants by Sara Gruen at the top of the best seller list for several weeks. I admit that our library doesn't often have very many of the books on the Register's best seller list, but we usually have two or three in our collection. I read a short review on this book and thought it was worth adding to our collection. I have not yet had the opportunity to read this book but initial response is very positive and those who have read it said it was enjoyable and that they would recommended it to others. Maybe some day I will get to read it and will find out just how much of the story is really about elephants.
