Rally Vincent promised to be a better sister. Upon returning to Boston, her main focus was to get a job and not get involved in the local supernatural politics. Easy enough, right, for a dhamphri? All she had to do is embrace her human side and ignore those dark vampiric thoughts. But when she finds out the demon who tortured her throughout her childhood is alive and assisting in selling vampire blood that, when consumed, can make anyone stronger (and insane), Rally finds it impossible to not get involved. Will her need for vengence lead her to sacrifice the very humanity she has protected her entire life or can she keep the vampiric side of her under control long enough to solve the case?
