The story was okay. I will say it was just entertaining enough to hold my interest through to the end (it didn't hurt that the book was a very quick read). I have to mention something about the sex scenes though- one in particular is quite crude, and I found the explicit detail there unnecessary. In general this is an average book... If it's one of many on your list, you're not missing much by skipping to the next one.
I haven't seen the movie, but I can imagine that the story may be a better fit in the cinematic format rather than the written one.
