I'll start with what I didn't like. The heroine, Carrie, has a "domineering" brother and a "bully" husband. You're given the impression that she's downtrodden and has low self esteem. But halfway through the book, there's no sign that her brother has any control over her life and she's already divorced. In spite of references to her mousy character and blah looks, she gives no sign that she's either mousy or unattractive. In fact, her actions completely contradict that.
This bugs me. Carrie's journey to becoming Dominique moved much too quickly. If the author didn't want to bother documenting her journey from one to the other, why even mention that she was transitioning? Why not just describe it as something that already happened? Instead I feel like I'm reading about a schizophrenic or two women instead of one.
I'm not expecting too much from erotica. There are many other authors whose character development - if there is any - is flawless. I just found this aspect of the book to be very clumsy.
That aside, if you can avoid being distracted by a self-described "mouse" acting wantonly, then you'll enjoy this book. If you like erotica you'll gobble up the many explicit scenes. It doesn't even matter if feminine domination isn't your thing, at least not in the first half of the book. The sex is relatively vanilla.
