San Antonio is on lockdown, taken over by the new hive. No one can deny that vampires are back now, but the Vanquishers come to their own painful realization when they learn that an old friend is behind the vampire attacks.

The Squad hide out at an abandoned combat training facility, honing their vampire-butt-kicking skills, but they begin to suspect that they're not alone . . .

When a vial of Dracula's blood--able to give unrivaled power to the vampire that consumes it--is stolen from the bunker, the Vanquishers race to recover it before it falls into the wrong hands. The Squad and the Vanquishers have always been Boog's family, the ones she trusts the most. But what does it mean when a former Vanquisher, one of her heroes, is now hunting them?
