Most likely it's because of all the hype and people reading it because they heard about it. Due to sheer curiosity about all the hubbub, I read through the first one and that was more than I could take. I found it to be mostly about the shock value. The man is abusive and the woman is a doormat who tolerates the abuse because he is rich and good looking and she "loves him" ... pffffffft. To me, this book feeds into the worst stereotypes men and women have to offer. It's strong sexual content was probably what created the stir and you can find that anywhere. I am the type of person that has to finish what I start and about halfway through, I found myself wishing I could read faster and wanting it to end.
I can't stand romance novels I find them cheesy, however if I had to read one give me a romantic or sexy story with an emotionally strong woman and a man who isn't a self-obsessed jerk over this book any day. This book had many grammatical and even some spelling errors also. There was a time we held published works to higher standards in both writing skill and story telling ability. The first book in this series was just awful. I wouldn't waste another minute of my life reading the other two.
