Hunting vampires is simple: find the target and deliver its head to the boss. Black and white, yes?
Adonai has been a hunter for a long time, and he's set in his views about the bloodsuckers he eradicates. Lukiel wasn't his original target, but a vampire is a vampire. He has to go. Except ... this one saves Adonai's neck and only asks for a favor before agreeing to be killed. It throws everything the hunter believed about these monsters out of whack.
When his conscience gets the best of him, he agrees to let Lukiel find his family first. The problem? If Adonai's comrades find out, he's in a lot of trouble. So he's stuck tailing an undead creature he's supposed to eliminate while hoping his indiscretion stays under wraps.
As events unfold, however, it becomes clear Lukiel's story is more complicated than it seems - and Adonai realizes his contempt is misplaced with this particular vampire. In time, their reluctant alliance may shift into something unexpectedly friendly ... maybe even affectionate.
