Vampires face extinction without human donors. A system matches willing humans, elevating their status. Vampire factions undermine it. Nyla is chosen by Prince Octavian, thrust into a world where humans resist being treated as livestock.

Fearing the demise of humans, their food source, radical changes are to be made or vampires face extinction. The Donor System is introduced, giving vampires their choice of humans selected from the system. This person is elevated in wealth and status in exchange for also being a food source. Small factions of vampires are tired of the truce and will do anything to undermine the system to prove they are the dominant species, while the human resistance grows weary of being treated like livestock. Donors began to be wiped out in a purge like fashion. In a chance encounter, Nyla James is finally selected by a vampire, the prince of vampires, Octavian Korvich. In a world wind affair, she is thrust into the spotlight and forced to be the new face of the Donor System.
