On the night of a crimson moon, Ethan Cross lost everything—his wife, his child, and his humanity. Taken as a Blood Slave, he was broken, drained, and left to rot in the dungeons of the vampires. But from the ashes of despair rises a hatred deeper than death. To survive, he must drink the very blood of his enemies. To avenge, he must abandon his humanity. From prey to predator, from slave to hunter—this is the story of a man reborn in blood, destined to carve his vengeance upon the world.
