Blood Rights — Kristen Painter

born into a life of secrets and service, Chrysabelle's body bears the telltale marks of a comarre -- a special race
of humans bred to feed vampire nobility. When her patron is murdered, she becomes the prime suspect, which sends her running into the mortal world ...and into- the arms of Malkolm, an outcast vampire cursed to kill every being from whom he drinks.

Now Chrysabelle and Malkolm must work together to stop a plot to merge the mortal and supernatural worlds. If they fail, a chaos unlike anything anyone has ever seen will threaten to reign.
