I don't really know what genre this book fits in. I suppose under romance, though when I think romance, I think of Tami Hoag (some of her stuff), Jude Deveraux, Judith McNaught, Nora Roberts... Oh, well, this is Jessica Brody's first novel, so we'll see. (And I didn't have a category for "chick-lit" so...)
The premise is interesting. A woman is hired by wives, girlfriends, fiancees, to test their significant other's fidelity. Thus, her profession as a fidelity inspector. I did read about such people in the UK called Honey Trappers. I have to admit, too, I visited the official website and the book trailer was a rather neat idea.
However, the writing stumbles a bit, and is somewhat repetitive. Yes, it makes sense for her to have two separate phones, and that Ashlyn is her persona and she needs to keep Ashlyn separate from Jennifer, but either certain facts are repeated too much or they're stating rather awkwardly and in such a self-aware way.
I did like the twists in the story, especially concerning a vaguely familiar client. I wish I could have known what happened with some of the couples she helped expose. And, that ninth name - I wonder what she did with that after she had help with it.
It was an enjoyable read. I wonder how one hears of such a person, and how rapid word of mouth is...
