Gemma's a successful architect in London, but her personal life has been a mess since her engagement ended in a very public disaster. She throws herself into work until a chance meeting with an aloof and dominating billionaire at a Christmas party awakens a side of her she never knew she had, a side that wants to let someone else take control for a while. Cole's got his own painful past relationship which is the reason all his bedroom encounters come with strictly defined terms, not to mention the reason that he hates Christmas. He's not looking for a change, but Gemma's unusual mix of confidence and submission leaves him wanting more. The two strike a deal to satisfy their mutual attraction, but will their sparks in the bedroom give new warmth to the rest of their lives as well, or is their relationship destined to bloom only for the holidays, just like the mistletoe?
