World famous MMA champion Zachary Barrett has returned to his home in Phuket, Thailand, and his elite training camp, Revolution. Thanks to his twin brother, a renowned pro trainer in Colorado, Zachary is primed and ready for his next title bout--but his toughest match may be with the sports journalist assigned to write an expose on him. Not only is she gorgeous, she's after a well-guarded secret that Zach soon realizes makes her off limits in every way... It's true that Kenzie Monroe has an ulterior motive for pursuing Zachary. The half-Asian beauty believes he's connected to her estranged father, a former MMA fighter who disappeared years ago.

But as lust, love, and friendship combine, Zachary knows he has to answer all of Kenzie's questions--because outside of the ring, the heart makes the rules...
