Katherine "Kit" Tolliver is the focus of the book, and she's a serial killer who has sex with men and then does away with them. She's very good at this and has killed who knows how many men. A lot. It appears that her childhood relationship with her father led her to this and that she's killing him, in a sense, when she kills the others. Or maybe that's too facile. At any rate, she has an unusual childhood.
It occurs to Kit that there are five men who've escaped her, and she decides that it's time to get rid of them, too. To do that she has to hunt them down, and it's not easy, considering that it's been a while and that some of them might not even have given her their real names. No matter. She turns out to be a very good detective, and her final relationship with each of the men is not always what she, or the reader, might expect. Oh, the end is the same, but each event is revealing in a different way. And as she tracks the men down to dispatch them, Kit even finds something that might even be love.
As I mentioned above, this book is about exactly what the subtitle says, and the sex is plentiful and explicit. The main character is a serial killer who makes Lou Ford look like a pussycat. That being said, the book is both savage and funny, engrossing and scary. You may have read some chapters of this book, as I had, in anthologies. Now you get the whole story, and it's a heck of a ride. Check it out.
