Rise of the Faceless Demon

The Eisenhart throne fell in a river of blood. Prince Luka lost more than his father and his crown to his traitor uncle, Ulric—he lost his humanity. Left for dead with a crude stitch across his skull and a shattered soul, the rightful heir was cast into the freezing, rotting slums of Oesteria to die as a crippled beggar. But the slums breed predators, not victims. To survive in a dying world under the shattered Red Ring Sun, Luka embraced the ultimate taboo: spiritual cannibalism. Devouring the hearts of monsters and men, he reignited his life force, mutating his own flesh into a horrific weapon. But power extracts a brutal toll. The Law of Erosion burns his past memories to ash, leaving only a pure, savage killing instinct. Now, armed with a monster's right arm and a heart void of mercy, the Faceless Demon rises from the mud. He is no honor-bound prince, nor a savior in shining armor. He is the executioner. To rip the false king from his throne, he will plunge into the darkest corners of Oesteria to forge an army as savage as himself—one slit throat at a time. — Description from novelcodex.org
