Heaven and hell have gotten tired of fighting and agreed to pin the fate of everything on one final contest, decided by one mortal man.
Jim Heron - chosen by both sides because he holds an even balance of good and evil - will affect the lives of seven people. If he tilts them towards good, heaven wins; towards evil and hell wins.
In the shadows of the night in Caldwell, New York, there's a deadly turf war going on between vampires and their slayers. There also exists a secret band of brothers like no other - six vampire warriors, defenders of their race.
Vampires aren't what we think. They aren't undead, they aren't evil, and while they do drink blood they mostly stick to the blood of other vampires. And vampires are nearly extinct, hunted for centuries by humans called lessers - humans turned into immortal soulless puppets by an evil god.
The Black Dagger Brotherhood is a band of vampire warriors bred and trained to protect their race from the lessers. Led by the vampire king, the brotherhood has dwindled to only a handful of men, each with their own secrets and dark pasts.
