Kit and Idris are bound by their curses. And in the fae realm, to break them always demands a price... On the eve of Prince Idris's eighteenth birthday, a grand ball is held for him to meet his intended, Princess Catharine. But for her ailing step-sister Kit, it is a night to hide in the shadows and avoid the unwanted attentions of her step-father, the king. Everything changes when Kit lays eyes on Idris, who somehow sees through her guarded facade to the secret she carries. Idris, however, hides a dark truth of his own. His family once wronged the fae queen and he has agreed to atone for their crime, even though it means dancing to his death. But he isn't the only one making dangerous deals with the fae. Kit's mother has a plan to save her daughter – by switching Kit's body with Catharine's.
