The Devil first visits Yetunde aboard a slave ship heading to America. Her home burned to ash, she lies shackled in the belly of the ship with only her dead sister's spirit for company. Worse, she has caught the eye of a white man. To survive the hell that awaits her, the Devil offers his protection and a piece of his supernatural power. In return, Yetunde makes an incredible sacrifice. Their bargain extends far beyond Yetunde's mortal lifespan. Over the next 175 years, the Devil visits all her descendants in their darkest hour of need. He offers each of them his own version of salvation, all the while wondering: can he save himself, too?
