Echo of the Blood Sovereign

Jaehwan was a hunter left for dead, betrayed by his own. Resurrected by a forbidden blood ritual, he is no longer just a man. He is a vessel for Kasian, an ancient vampire sovereign whose soul screams for its lost queen. That queen has been reincarnated as Elara—the very woman Jaehwan once loved and irrevocably broke. Now, bound by dark power and a predatory obsession that isn't his own, Jaehwan must fight the monster within him to protect Elara, even as the sovereign demands he claim her, possess her, and drown the world in blood to have her back.
