The Witcher's Blood Pact

Chen Duhan awoke from unconsciousness to find himself hanging in the dungeon of a vampire stronghold. Chains bit into his wrists. His last memory was of his squad walking into an ambush, his comrades' screams swallowed by the night. The woman before him was called Luo Ning, commander of the vampires' Seventh Legion. Those dark-red eyes were measuring every inch of his wretched state. Chen Duhan had heard her name two years ago, when the vampires tore up the armistice. More demon hunters had died at her hands than from the plague, yet no one had ever seen her true face—because all who did were dead.
