Query: Very different from the movie

As the title of my review implies, this book is very different from the movie as is often the case. I saw the movie as teenager, and didn't even realize it was based on a book. Typically I read a book before watching the movie. This book really makes you think about the issue of sex for money and delves into psyche of the main character. I like romances and happily ever after, and this book doesn't give you that. However, it does really make you think, and for that reason I'd recommend it.
