Darkness (Demons, Gods & Goddesses Trilogy) by Laurie Ann Butcher

On a cold and grim night, high up in the Carpathian Mountains of Romania, Hotarat Vanator meets with fate.

Tormented by the knowledge that his tribe may not survive the brutal winter, he returns empty-handed from a hunt only to have his worst fears fulfilled. His tribe has been virtually annihilated… but not by hunger. They have all been murdered and mutilated. All that remain are himself and the four men who had accompanied him on the hunt.

Cloaked in darkness, the five men blindly comb through the village, desperately searching for survivors, but what they find instead is certain death.

As the night progresses, the silence is shattered, and one by one the men fall into the clutches of death—until only one man remains—Hotarat Vanator, the hunter of the tribe… but the hunter has now become the hunted.
