REVIEW CONTAINS SPOILERS! First of all, this is not BDSM. Not sane, barely safe, just short of consensual, and no safe word. Definitely more coercion-based.
The premise is that the female character did something bad and is on the run from the law. She agrees to stay with three men in a secluded home on the bayou (one of which is a childhood acquaintance with a grudge against her) in exchange for protection from the law, anonymity, and her complete submission to the three men without resistance. This is problematic for me for several reasons. The childhood acquaintance is hell-bent on punishing her for her rejection of him in the past, and making it clear that her only two choices are to leave and face the consequences of what she's done or stay with them. Not sane. She frequently tells the men no, she doesn't want to do something, and they tell her can leave if she doesn't like it, that she agreed to live there and do whatever they say in exchange for protection. Coercion, not consensual, despite the female lead's agreement to participate. She didn't know what she was agreeing to, just that they wanted to use her. The men tell her that she is safe with them, they will protect her, but seem disinterested in her mental safety or aftercare, and even let a guest abuse her. Not safe.
This whole plot was set up so that the female lead could discover that she enjoys the humiliation, the whipping, the submission, and the rest. However, there are better ways of going about this discovery, and this plot point fell very short of the mark. We pretty much understood before that self-discovery "revelation" at the end of the book that she was really turned on by the spankings. No mystery here.
None of the characters were well-developed, but we did get a few two sentence long back stories for the male characters.
Apart from all of these thin plot devices, the book was very clinical in the way sex was described. This is erotica. Come up with a different word for someone's "bottom". Every time I read "bottom cheeks", I rolled my eyes. There are so many descriptors that could have been used in the sex scenes, but it just seemed underwhelming to me, and in the end I just want to skim them because they all seemed to read the same.
In all, I was hoping for more from this book. I was hoping that the female lead would discover she holds all the power, or that she would learn that submission doesn't mean giving up your free-will. Nope. What a disappointing read.
