Save her life…or save mankind. His choice could cost him his soul. For nearly two centuries, Marcus has been the Watchers’ most faithful soldier. Sworn to protect humanity, driven by an unrelenting compulsion to atone for past sins, he has rarely found a compelling reason to question his mission, let alone defy his leader. His partner, Regan, is his exact opposite, an enigma he longs to solve. A free spirit and reckless to a fault, Regan acts first and thinks later. Her smart mouth and tender heart have fascinated Marcus for decades, but the Watchers’ strict vow of celibacy has forced him to ignore the sizzling attraction between them. Until now. When Regan goes rogue to protect a very special little boy, Marcus is forced to make an impossible choice—commit an act of treason or watch the woman he secretly loves die. Hunted by enemies and allies alike, Regan and Marcus run for their lives, fighting to thwart an age-old prophecy and guard a boy whose destiny may very well be to destroy the world…or save it. Warning: Contains violent battle scenes, angels with twisted agendas, nail-biting suspense, intense emotion, burning-hot sexual tension, and a sexy, stubborn hero who would rather face death than admit what’s in his heart.
