In a kingdom where knights fail and prophecies falter, the fate of Calyndar rests in the hands of a lady-in-waiting who was never meant to wield a sword—let alone a legend.

In the kingdom of Calyndar, winter doesn’t just bring frost—it heralds the terror of the Manticore. This monstrous creature ravages villages, destroys food stores, and leaves a trail of despair and death in its wake. As desperation grips the land, a long forgotten prophecy emerges: only the one worthy can retrieve and wield an ancient sword capable of defeating the beast. But when the realm's mightiest knights attempt and fail to claim the blade, hope falters in the kingdom.

Sylvene Brightmoore, a lady-in-waiting burdened by her past, struggles to fit into her appointed role. Raised under the pitying gaze of King Valric Hawthorne and adopted sister to his daughter Princess Lilia, Sylvene is beautiful, clever, and yearns for more. Each night, under the cover of darkness, she trains in secret, driven by an unyielding determination to never feel powerless again. When she effortlessly draws the fabled sword from its enchanted statue, she shocks the patriarchal kingdom—and angers the king.

Cast out from court, Sylvene must slay the Manticore or never return to Calyndar. The king assigns Sir Hale Carrow, the knight who had quietly nurtured Sylvene’s potential, as her reluctant protector. Together, they must navigate deadly traps, cunning enemies, and their own growing feelings for one another—all while fighting for a kingdom that doubts them.
