Caleb O'Connor is a werewolf, but he doesn't believe in magic. He breaks out of his reclusive community in Maine to go to MIT, hoping to fit in on a campus where no one believes in monsters. But one evening two of his friends die in an abandoned Maine mansion, and one of his professors tells Caleb that this was the work of a vampire. Together they travel to Romania to unlock the secrets of an Undead cult that terrorized the Old World for centuries and moved to the New. First in a trilogy.
