I suppose I should start with the literary aspect of this book. Aside from the sex and bdsm relationship, there's not really a plot in this book. It's written in the first person, as seems to be the fashion lately. The main character is a senior in college virgin who falls for a 27 y.o. businessman, gets rid of her virginity and then tries out his lifestyle. Their entire relationship lasts 1 month and of course, she falls in love with him. The sex scenes were definitely not my bag of tea, but then, I'm not into bdsm. 
 It must be because the author is English and not American, but instead of writing "I haven't", she wrote "I've not". I've only heard Americans in South Carolina put their contractions that way, so that annoyed me. A lot actually. Another thing that put me off is when the main character is having conflicting thoughts, her "inner goddess" and "subconscience" would talk to her. I'm sorry, but voices don't speak inside my head. 
 Now here is my main problem with the book: no matter how much you tell me it was "mutually agreed upon", I couldn't get past the punishments. That is domestic violence and she was not okay with them! She was scared of him and scared of him getting upset and taking it out on her. This is Domestic Violence, people! I almost didn't finish the book because it was so upsetting to me. I was hoping that she was a) use a safe word to make it stop and b) would punch him in his face and kick him out. As far as the other books in this series - no thank you.
