The Vampire King Series: Book One.
Sometimes duty was a bitch.
Pulled back to a place he viewed with indifference, all Victor Cayne wanted to do was find out what was going on then haul his rear out of there, but unfolding events set him on an unexpected path. Locked into a time limit and stuck with a mortal female, could he navigate all his problems without losing his sanity? And if he succeeded, what would he find at his task's end?
The first installment in the Vampire King series.
