In this romantasy from the New York Times–bestselling author, a soldier enters the supernatural realm when he takes on a mysterious and beautiful accomplice. Mercenary Leo Alvarez has seen a lot of action in his lifetime. But nothing prepares him for the revelation that his best friend Jackson has the soul of an ancient Egyptian pharaoh inhabiting him. Fighting battles is one thing, but taking on otherworldly beings is a whole new kind of war. When Jackson is attacked by a demon, Leo is forced to partner with a Night Angel, a mystical creature who is his only hope of saving his friend. And though Faith is unlike any woman he has ever encountered, Leo is consumed with desire at the sight of her. Joining forces with her is electrifying, sensual—and powerful enough to take on the darkest of evils.
