The Void Within by Tyler Bourassa

An undead warrior bound to a tyrant begins to remember what it means to be human—just as he’s ordered to forget it forever. Del Famir does not feel. Once a warrior, now an undead servant bound to a cursed sceptre, he exists only to obey—summoned to violence, dismissed to emptiness, and stripped of everything that once made him human. Memory is gone. Emotion is gone. Only duty remains. When he is tasked with retrieving a runaway slave named Deirasa, he expects nothing more than another command fulfilled. But Deirasa is unlike anyone he has encountered in centuries. She sees something in him—something he cannot see himself—and refuses to accept that he is nothing more than a weapon. As the ambitions of their cruel master threaten to drown a city in blood, Del Famir finds himself drawn into something far more dangerous than war: connection. With every passing moment, fragments of his past begin to stir, and with them comes a pain he had long been spared. Because to remember is to suffer. And to feel again may cost him everything.
