Plagued by misfortune, Ingrid Norling treks into the woods to clear her head. She emerges a monster-slayer, the shaken executioner of a creature so ferocious that even the king's strongest warriors could not destroy it. In a land that reveres swords and worships strength, this accidental heroism earns Inge an audience at court and an ill-fated prize: King Halvard impulsively adopts her and names her as his heir.
Under constant guard to prevent her escape, Inge confronts the ignoble underbelly of the royal court: a despotic king, a clueless princess, a proud warrior, and a dangerous intrigue. As secrets unravel and the castle becomes an elaborate deathtrap, Inge must keep her wits close and her weapons closer.
