Apparently it's deep in the first person of a very naive and vanilla female protagonist, and there seems to be a lot about how her love will "cure" the male protagonist of his lifestyle. I don't believe that's how it works. I can see why some women would like that as a fantasy, and what probably feels like to them a naughty fantasy, but it doesn't sound like the kind of book I'd like.
If I want to read about Dom/sub relationships, I have a lot of good books to go to. I can read something of James', or Buildup: Mindscan, which I adore, or One Real Thing, to name just a few. I read Natural Law on TeddyPig's recommendation, and it's probably the only romance I've liked that has a Domme. I could read some of Simon Sheppard's stories. I don't think being kinky is something to be cured of.
Without having read that particular book, that's the impression I get of it from those reviews and commentary.
