Water for Elephants-A complete surprise

I recommend this book, not because it's pretty much a chick novel and is released as a movie now, but because to me it's evident that the author researched Circus/Carnival history and has an interesting story to tell, much of which is true, go ahead, google it.

I loved it, the ending is - not fall off the wall, "I gotta end this book"- but went just where I'd want to go if I were in the main character's situation. How often anymore do we get an original plot line like this?

Will see the movie but worried about how it's treated.
