Natalie and Caleb have an unconventional marriage. She is dominant, he is submissive. After he catches her cheating they agree she can see other people as long as she tells Caleb about it. This is working for them, but it could be better, and neither partner is being completely honest.

Natalie's step-brother Dylan is ten years her senior. He has a tumultuous relationship with his wife Monique, and when they fight he regularly stays with his step-sister for a few days before patching things up. Caleb is attracted to Dylan. This is one of his secrets.

Over the course of Dylan's one-week stay, eyes are opened and truths are told and Natalie and Caleb gain a deeper understanding of one another. Along the way there is much angst and drama, and a lot of sex which is off-the-charts hot!

If you are troubled by things that might happen between adult step-siblings in a work of fiction, then this is probably not the book for you. Dierdre Winter has a knack for bringing humanity to characters in extreme circumstances, and she does a great job here. I was initially troubled by signs of emotional cruelty between partners in this story, but a large part of their journey is realising things could be better and making them so.

An entertaining, and very sexy, read. Highly recommended. ( )
