Yes...it is exactly that. Well, not exactly. Apparently, this is the book that E.L. James got some of her ideas from...that and Twilight. And while I didn't really get a lot of Twilight from this book, you can definitely see the things that E.L. James picked out of it. As far as it being a fan fiction, the only clue I had was the lack of the character's physical descriptions. That being said, I really enjoyed it. I'm not sure what's happened but this story line has not gotten old for me. Each story seems to have enough differences to keep me entertained...and entertained I was.
