Daughter of a Fallen Angel — John Boyle

A fallen angel decides her enslaved daughter, Sachi, needs a husband who can appreciate her good qualities and overlook her tiny-little flaw. Traveling to Earth, the angel discovers a perfect specimen on a sinking trawler and hopes she can get away with a little karmic interference. Matthew Sharpe, an American descendent of the rebellious Jamaican Maroons, has major issues with waking up in a slave-owning culture on another world. However, he finds the cute slave girl, who's assigned to nurse him back to heath, the most desirable female he's ever encountered. But the city is at war with a monster army, and one of the ruling witches knows of Sachi's true heritage. Fearful the girl might awaken to her power, she convinces her sisters that Matthew is an enemy half-breed sent to penetrate their defenses. Between avoiding death by the suspicious witches, fighting the attacking monsters, and dealing with a lover who's finally had enough of being a slave, Matthew learns some love affairs are more complicated than others.
