The city lights of Valenfort burned bright against the suffocating dark like a gem tainted by blood. Beneath that glittering surface lay nameless alleys where the scent of iron and the echoes of screams intertwined into a symphony of hell. No one remembered the last time they saw a real sunrise for this city had long belonged to the night. Evelyn Cross , a fourth-generation vampire hunter of the secretive order known as The Order of the Thorn , was born in blood and sworn to die for her mission. She had once watched her father torn apart by a pureblood vampire, a creature so fearsome that humans dared only whisper its name in prayer. Since that day, Evelyn lived like a blade cold, unfeeling, and driven by the hunt. Until she met Lucien Draven , the Blood King of Valenfort who ruled the shadows with a calm smile and eyes that could stop a heartbeat. Lucien did not kill Evelyn upon their first encounter. Instead, he saved her from the very comrades who had betrayed her. A vampire saving a hunter such a thing had never happened in the history of either world. Evelyn despised him… yet could not kill him. Lucien desired her… yet knew his love was her death sentence. In Valenfort, a war of blood is rising. The ancient vampire houses are clawing for dominance, while the hunters’ order fractures under betrayal and deceit. Amidst gunfire, betrayal, and desire, Blood War is not merely a battle between species but between the heart and fate itself. “In the world of darkness, truth isn’t written in ink… but in blood.”
