Hungers of the Heart

Drake is a Killer vampire.
Unlike the Guardians of the Night, Drake feeds on human blood, choosing victims who deserve to die. But still he works with the Guardians to protect those humans who yet have some good in them.
When Gabriel, the leader of the Baltimore Guardians, mysteriously disappears, Drake finds himself in charge of a small band of inexperienced fledgling vampires. When a delegation of European Killers arrives in Baltimore looking for Gabriel, Drake must call on all the savagery of his sordid past to keep the Guardians in line—and to protect them from the ruthless Killers.
Forced to confront a past he has tried so hard to outrun, Drake risks losing his humanity. His only hope is Faith, the French Seigneur's concubine, who desperately needs his help to rescue her human sister from the Seigneur's clutches. Then someone begins killing the members of the European vampire delegation, and Drake is the only suspect. Will Drake be saved by love, or will he become a Killer without a conscience?
