The quality of the writing was abysmal. Not only was the main antagonist immature, I felt like the book was written by the actual antagonist. I cant hear the term "inner goddess" without a visceral reaction to it. Writing style aside, the actual relationship was entirely unhealthy. I didn't read past the first book because lets be honest, after that kind of situation only a retard would continue with the relationship.
I read it simply because i have long practiced BDSM in my personal life and several people I know wanted my opinion of it. My opinion is, even the scenes were boring. They were without great detail, and they were SHORT. Super short. He spent more time setting up a scene than doing anything, then he would cum and it would be over. After reading the book, I researched and found out the author was a "Twihard" who simply wrote this as a fan-fic. Not only that, she doesn't participate in BDSM in her personal life and barely did any research at all. That shows immensely in the lack of thought or scene playout.
Pro-tip: it was abuse, not BDSM. She cried EVERY TIME she went home. Sounds healthy.
To the general inexperienced "missionary on Sunday" masses, this was a literary erotic masterpiece. If you know anything at all about how it really works, its pretty crap. But then again, I am analytical. I know women who are in the scene and LOVE the book. Most men think its garbage.
To lighten the mood though....enjoy the audio book as read by Gilbert Goddfried. Seriously, even if you cant stand the guy like I cant, this will change your life.
