Poppy had always loved the night, which is why it wasn't too much of a bother to wake one evening in an unfamiliar home far from London, weak and confused and plagued with a terrible thirst for blood, to learn that she could no longer step out into the day. And while vampirism presented several disadvantages, it more than made up for those in its benefits: immortality, a body that could run at speed for hours without tiring, the thrill of becoming a predator, the thing that pulls rabbits from bushes and tears through their fur and flesh with the sharp point of a white fang. And, of course, Roisin. The mysterious woman who has lived for centuries, who held Poppy through her painful transformation, and who, for some reason, is now teaching her how to adjust to her new, endless life. But overhead, threat looms--one woman who is capable of destroying everything Poppy and Roisin hold dear.
