A half-faerie princess must survive a politically arranged marriage to Atakan, the heartless Seelie prince who openly despises her. Their encounters over the years leading to the wedding grow increasingly terrifying as he lives up to his monstrous reputation, yet she learns to mask her fear and finds herself dangerously drawn to him. Just as she begins to believe she can tame him, fate intervenes and delivers her into the hands of his Unseelie enemy, raising the stakes for both their world and the fragile connection between them.
