Dave is working at Desmond's house, but shelves aren't all he's building. The attraction between Dave and Des that began in Book 1: Meet and Greet has taken off, with the blessing of both their partners. Wyatt seems amused by Dave's nervous double checking, and Archie expresses his approval by bedding Dave with enthusiasm. As the only non-kinky one of the four, Dave isn't sure how open he's prepared to be, but he really does like Des. In Book 2: Mix and Mingle, lines blur when Dave and Des have their first date and their first experience together. Elated at the success of it all, Dave heads for home, only to discover that he's not the only one with lines that can be crossed. Just how open can Dave's heart be and how much are all four of them willing to accept in order to be together?
