I saw an interview with the author the other day on Good Morning America or some show like that. I'll admit that I was talking on the phone at the same time, so I only caught bits and pieces of the interview. I thought it was just a run of the mill romance novel, and thought, oh, what the heck, I'll check it out. Downloaded the e-book. OMG!! Yeah, I'm no saint, but there is some stuff in there I had never heard of or imagined before. Yikes. I'm only about halfway through the book, but yeah, I'm torn between reading non-stop until I'm done, or stopping before my innocent little mind is corrupted! LOL I'd be afraid to tell my husband what I'm reading, lest he decide he wants to try some of this stuff! Hahaha...
ETA: Okay, I'm halfway through the second book now. My take on book #1 is that beyond the racy aspects of it, it is not all that well written. I am getting really tired of "Oh my." Who says that? (75 times a day?!) Also, some of the conversations seem stilted to me. For instance, when is the last time someone said, "How do you do?" instead of "How's it going?" or "How are you?" or "Nice to meet you." Things like that interrupt the flow of the book, in my opinion. The other thing that bothers me is that Ana is apparently no great shakes in the looks department, which is not believable. Christian is not only gorgeous, but he's a self-made billionaire (also slightly unbelievable, since he rarely seems to work, and is only 27??) - I can't imagine that he saw a klutzy, disheveled college student and thought, "I've got to have her!" I don't know.
Anyway, the second book seems better. More plot, some danger (crazy ex with a gun!), more interaction with other characters in the book, and Christian and Ana's relationship seems slightly more realistic. So, there's hope for this series yet.
