Zera is a Heartless—the immortal, unaging soldier of a witch. Bound to the witch Nightsinger, Zera longs for freedom from the woods they hide in. With her heart in a jar under Nightsinger's control, she serves the witch unquestioningly. Until Nightsinger asks Zera for a prince's heart in exchange for her own, with one addendum: if she's discovered infiltrating the court, Nightsinger will destroy Zera's heart rather than see her tortured by the witch-hating nobles. Crown Prince Lucien d'Malvane hates the royal court as much as it loves him—every tutor too afraid to correct him and every girl jockeying for a place at his darkly handsome side. No one can challenge him—until the arrival of Lady Zera. She's inelegant, smart-mouthed, carefree, and out for his blood. The prince's honor has him quickly aiming for her throat. So begins a game of cat and mouse between a girl with nothing to lose and a boy who has it all. Winner takes the loser's heart. Literally
