Carolina has spent her entire life convinced she's ordinary, the unremarkable daughter of a duke while her sister basks in magical talent and noble expectations. Everything changes when the kingdom arranges her marriage to the notorious "Bloodthirsty Prince" of a rival empire. Thrust into foreign courts where political intrigue cuts deeper than swords, Carolina discovers she's anything but powerless. A latent gift runs through her veins, one that activates without her awareness, radiating outward and reshaping the world around her. Those closest to her notice first: the prince begins to question everything he believed about power and duty, while enemies of the state find their ambitions crumbling mysteriously. As Carolina navigates marriage to a man she hardly knows, court conspiracies close in from all sides, and the weight of her uncontrolled abilities grows heavier. She must learn who she really is before her unconscious strength becomes a liability for everyone she cares about. Romance blooms in the shadow of danger, forcing her to choose between the safety of ignorance and the risk of claiming her true power.
