Couldn't pass up on the PS0.00 offer on Amazon Kindle Unlimited. 
 And now I want to read the next two books! 
 If you're into that sort of thing (by which I mean dark erotica) you are going to be extremely bored for the first half of the book, and then you actually might enjoy it. 
 Half way through I was tired of all the mentions of how cruel and capable of hurting others Sin was, while apart from a few harsh words and devious smirks he acted like a lovesick puppy. 
 Then it gets better, and by the end we actually get some background story to the Vinemont family history and what this bloody Acquisition business is all about.
