After surviving a vampire assassin (not to mention an awkward affair with a hot FBI agent that ended worse than she could have imagined), witch/vampire hybrid Nina Martinez is reunited with the full Blood Ops team in Providence, Rhode Island. Her Aunt Babe is tutoring her in all things witchcraft, and her vampire partner Frankie is enjoying the benefits of daywalking, courtesy of a demon spell.
When a segment of the Rhode Island vampire population is marked for death by a tainted blood supply, Nina and her team race to find Patient Zero before the local vampire population is wiped out. But when a demon infestation threatens to take control of the city, Nina must join forces with newly elected mayor—and closet demon— Ami Bertrand before the city falls into ruin.
Filled with fast-paced, edge-of-your-seat action, Nina and her group of supernatural misfits battle a surprising new enemy that threatens their very existence.
