Stopping him cost them their careers and almost their lives. Thanks to an influential and anonymous benefactor, Drake and Alison find a new job ridding the streets of Washington D.C. of the vampiric threat terrorizing the nation’s capital. Only this time, Drake and Alison are not facing a single vampire but an entire nest led by Ion Zielenska, one of history’s most evil and twisted masters.

Orchestrating the carnage is Antoinette Varela, the mistress of the nest, who realizes that for the nest to survive the hunters must be eliminated. However, when her vendetta turns personal, the hunters find themselves in struggle they are not prepared for.
