When a mission to recover a stolen magical locket draws her into a web of political bargains with Cordell’s royal court, she confronts the cost of freedom, a complicated bond with a prince, and the expectations of her commander. As secrets about her heritage and a dormant power surface, she must choose between personal desire and the fate of her shattered kingdom, setting the stage for a rebellion to reclaim Winter.
