Regan is a vampire hunter. She prowls the night in search of her targets. Yet, she also hides a dangerous secret – she is a former vampire, who put herself through sheer torture to transform into a normal being. The world as Regan knows it is full of creatures of the night – vampires, Nosferatus, weres. Humans are a dying breed, and disease and vermin runs rampant among the mortals. It is hard to find untainted blood to survive.
