Noah Parks is the ridiculously gorgeous, motorcycle-riding, cage-match-fighting equivalent of kryptonite for Lindsay Harper. And she's going to need every last ounce of her strength now that she's the legal guardian of her brother's five orphaned children. For the sake of her new family, it's time to give up her carefree single ways. Stop being the cool aunt and become a parent. And fight this crazy attraction to Noah. Sure, there's a side of him she can't help falling for…the one who volunteers as a firefighter and helps at-risk youth. The irresistibly kind and caring side. But she is a nurse, after all. She can't love an MMA fighter, a man she regularly has to scan for physical trauma… Can she?
