For more than two thousand years, a small community of humans has lived in harmony with vampires, giving their blood and obedience in exchange for protection. And for all that time, it’s been a peaceful occupation.

When Kalyn Reid comes of age and pledges herself to the vampires, she has no reason to worry. She’s paired with Anselm for her training, and she couldn’t ask for a kinder, more patient mentor. She also couldn’t ask for anyone better-looking.

But before she has a chance to learn her new responsibilities—or get a date—her idyllic life goes up in flames. Without warning, the humans and vampires in her group are murdered by a strange new type of vampire and the few survivors are forced to flee.

Anselm and his brother, Micah, vow to hunt down the murderer, and they take Kalyn with them—thinking they can keep her safe. But when the killer finds them first, it’s they who must rely on her if any of them are to survive.
