MMA fighter Harmony "Harm" Makos steps into the ring every day for more than the fame and glory of the fight. For her, it's the alternative to therapy. An opportunity to tame the constant beast struggling to break free. Hardened by a broken home and high school ridicule, she's learned to control the fury but it always lurks beneath the surface. When a threat on her life arrives in the form of an ominous letter, a bodyguard is assigned to follow her every move. Harm is immediately against the idea, and the animosity rises when said bodyguard is none other than former MMA men's heavyweight champion, Mars. Between their heads butting at every turn, forced proximity, and constant banter, Harm will discover Mars isn't all that he seems. Around him, visions of battle, chaos, and destruction plague her thoughts. The red glint in his eyes holds more than mystery-it bears the unknown cure for both their fury...if they can learn to work together, that is.
