Noelle Adams/Claire Kent has pretty much become an auto-buy for me. I've enjoyed everything I've read of hers. Some more than others, but I've not actively disliked any of her books. I liked this one. It is short and it does start in the middle of an active sexual relationship. Victoria is a librarian and she's stepped out of her comfort zone and volunteered for a political campaign. While working on the political campaign, she meets Greg. He's a businessman working for his brother's campaign. He's also a widower with an older teenaged daughter (I think 19), but Victoria doesn't know about the daughter and the daughter doesn't know about Victoria. Greg and Victoria have agreed to have a purely sexual relationship and they don't know a lot about the other's personal life. Until the teen daughter finds out about Victoria and confronts her. The daughter, Carrie, does it at Victoria's place of work and not in a nice way. The story goes from there with Victoria's feelings about dealing with this conflict, given that it's supposed to be a purely sexual relationship.
There is a lot of sex. And, although it's a short story, there is plenty of character development and I was able to sympathize. I liked this a lot.
