Eternal Reign

Humans in this ruined world are kept in cages as livestock, farmed for their blood. The narrator and her twin have stared through the fences for years, knowing the only way out is in the grip of a vampire. When the annual testing approaches, and those who pass are never seen again, the sisters decide to run before the royals can claim them.

The escape fails. An original vampire prince, who has never claimed a human before, takes the narrator for his own. She is now held in his castle, bound to become his creature, and pulled into a rivalry between the vampire princes.

Her twin is in trouble of a different kind. She has become entangled with the last slayer alive, a man covered in tattoos who is hunting the same royal vampires that hold her sister. The gods have placed the twins on opposite sides of an ancient war.

The narrator decides to play along, letting her captor use her as a puppet while she waits for a chance to strike. This is dark fantasy romance in an enemies to lovers vein, and the first line of the cover warning is plain: the vampires are savage and bloodthirsty, not gentle. It is written for adult readers (18+) and carries a brutal, violent tone. The authors also wrote Zodiac Academy.
