In a world where legendary Birth-Blades are the very essence of their wielders, master smith Calanthe Lark adheres to a creed of unyielding perfection. Her forge is a sanctuary of fire and steel, until a shadowed figure arrives, bearing a blade shattered not just in metal, but in spirit. This isn't just about restoring a weapon; it's about mending a soul, and perhaps, altering the course of an entire realm. As the fractures run deeper than steel, Calanthe must confront a truth that could unravel her own rigid principles and expose an ancient, terrifying connection. Prepare for a dark epic fantasy where the fate of kingdoms might hang by the strength of one meticulously mended blade.
