All he wants for Christmas is a temporary fiancée—but he's about to get more than he bargained for . . . If pretending to be engaged helps them both, then why not? For so many reasons . . . As a hotshot developer, Tate Duncan is used to, well, developments. But finding out he has a long-lost twin brother and a family he never knew throws him for a loop. Now his newfound family has invited him to travel from Seattle to London to celebrate Christmas with them, and he doesn't know where else to turn for advice other than to sympathetic, sexy, down-to-earth Hayden Green. Will she come with him and pose as his fiancée? Just to be his anchor in the storm . . . Though she now runs her own yoga studio, Hayden has always known that she and Tate are from opposite sides of the track. Being Tate's friend, even posing as his fiancée for the trip, is all fine. But when their holiday getaway gives rise to real romance, how can she tell Tate that she isn't the woman he thinks she is? That she isn't worthy? He's already dealing with shocking family secrets of his own. Will hers bounce her right out of his bed—and his heart?
