An exile. A mark. A war in the shadows. Isen Delmire was born into one of Zenith’s most powerful families—until his Calling left him with a power deemed worthless. Cast into Deadreach, the rotting slum where the discarded fight to survive, Isen learns weakness means death. But his strange Mark—the swirling gray emblem he can leave on others—isn’t so useless after all. Taken in by a man with dangerous ambitions, Isen begins to change. Hardened by pain. Sharpened by purpose. Forged into something new. And when he returns to the city that cast him out, it won’t be for forgiveness. It will be for blood. Perfect for fans of dark magic, morally gray assassins, and high-stakes rebellion, Graymark is a ruthless fantasy about power, vengeance, and the cost of becoming what they fear.
