She's kept her heart on maximum-security lockdown… Growing up, MacKenzie learned early on that love was something other people experienced, something she'd seen but never felt. When she meets MMA fighter, Ian, she expects nothing more than a one-night stand, but he walks away before they seal the deal. Now she'd like to forget the night they almost hooked up. But she's just taken a job working at his gym, and despite her efforts to move on, his allure is overpowering. When Ian gets injured, they begin working together on his rehabilitation, and their one-on-one physical therapy sessions are so hot they sizzle, leaving them both desperate for more contact. The battle for love is about to become a fight to the finish.
