Absent in Absinthe — Kierstin Cherry

All the vampyress Alidri wanted to do after the war ended was find the cure to the poisonous curse that racks her Ordog slave and would-be lover, Adora, keeping them forever apart. But when an ancient Queen of Zombies rises to threaten the rightful crown of Vespertavia, Alidri must heed the call to battle. Reluctantly setting aside her quest for a cure, Alidri swears to destroy the Zombie Queen and her hordes of undead.

But the Queen is none other than her sister she thought dead these past hundred years Now torn between duty to family and duty to the crown, Alidri fights the undead army closing in while the cure for Adora slips farther and farther away. Still, every night Adora fights alongside Alidri--forever by her side, forever unable to touch her, to kiss her, to take her as she wants. To make matters worse, Alidri learns her sister needs only one thing to realize her true power--the blood of the last living Ordog. Adora.

When her sister kidnaps Adora with the intent on sacrificing her, Alidri is forced to face the Queen of Zombies on the field of battle and fight for what is most important to her. But will she choose her duty to the Crown or her love for Adora?
