A young girl, on the cusp of maturity, in what is now known as Benin, West Africa, is seduced by a beautiful stranger, a man the likes of which she has never seen before. Their encounter changes her forever. She runs, her travels taking her to Europe and the Caribbean over centuries to escape him. She finally settles in New York City, convinced that she has eluded him, until she falls in love. She becomes an asiman, a vampire, one of the undead. The Promise Keeper comes to her, willing her to do his bidding; to keep an unspoken promise. He probes her mind and plants suggestions, so she will follow his plan, until she fights back.

The Promise Keeper is a story of love, despair, murder, and deceit. It is also a vampire tale like no other. Could you keep this promise?
