The Rivers Will Run Red

In the wake of a devastating attack by a rogue coven of vampires, hunter-turned-werewolf Ileana returns to the ruins of her family home. Believing her sister, Tamara, survived the attack, Ileana seeks the help of Liviu, the werewolf who turned her, and Evdochia, a hauntingly powerful vampire descended from Vlad Țepeș himself.

The attack is the first strike in a looming war threatening the fragile truce between humans and mythical nightwalkers. With time slipping away and danger closing in from all sides, Ileana and her allies must race to find Ravenswatch, the ancient fortress where the vampire coven is preparing to strike again.
