When Hartley Billings is selected to compete on her favorite reality TV show, she only needs to do two things to win a million dollars: Come in first place in the final leg. Not murder her teammate. The last step would be a lot easier if she wasn't paired up with her ex, AKA: the guy who obliterated her heart in college. Court Mueller isn't thrilled either. His one shot at earning prize money and escaping his lackluster life in Green Valley rests in the hands of the woman he gave up six years ago, AKA: the one he's stuck with 24/7 for the next three weeks. With their thorny past now their present, Team Hartbreak only needs to do two things to survive this season of Xtreme Quest: Establish clear boundaries. Never, ever cross them... no matter how tempting it is. 'Ex Marks the Spot' is a full-length contemporary romance and can be read as a standalone.
