Fifty Shades Freed by E.L. James (2012)

I wasn't going to admit that I finished the series, but I did. Yes the writing is bad, and the story got worse as the books progressed, but I was too curious to see where the writer would take it. So in this book they are married and Ana finishes "freeing" Christian from most of his demons and he becomes a semi-normal human being and family guy. I kinda liked what the author did in the end - giving us a glimpse into Christian's childhood and then the first two times he meets Ana from his point of view. So you see he has come a long way.
