Josh North is UFC's Light Heavyweight Champion-but he's about to meet his match. Sophie Garner is a single mom who's been raising her daughter on her own, fighting for both of their lives ever since going into hiding to escape her abusive husband. When Sophie gets offered the job of a lifetime as the exclusive massage therapist for Josh "The Jackhammer" North's team, it's difficult to say no to the outrageous salary-and the bet-that Josh proposes. But for Sophie it's a risk that could cost a lot more than just her heart - if she's found, it could cost her her life. Should she dare? Josh wants to break through Sophie's fortified walls, but is unwilling to put the jackhammer to his own and reveal his secrets and the side of him few have ever known or seen. To do that, he'll have to confront the darkness of his past. Will he dare?
