But now that the threat to the vampires has been defeated, the human residents are learning that the gravest danger they face is the enemy within. Thanks to the eradication of the parasitic creatures known as the draug, the vampires of Morganville have been freed of their usual constraints. With the vampires indulging their every whim, the town's human population is determined to hold on to their lives by taking up arms. But college student Claire Danvers isn't about to take sides, considering she has ties to both the humans and the vampires.
