Zera – Heartless. An immortal and eternally young puppet in the hands of the forest witch Nocturna. She longs for freedom, but is forced to obey her mistress, who keeps her heart in a witch's vessel. One day, the witch offers a deal: Zera's heart in exchange for the prince's heart. But if she fails and is captured, Nocturna will destroy her in order to protect her secrets.

Crown Prince Lucien d'Mulvane despises the royal court because everyone grovels before him. Mentors are too afraid to actually teach anything. And the ladies-in-waiting fight for the attention of His beautiful Highness. No one dares to challenge him - until Lady Zera arrives at court. She does not look like a sophisticated aristocrat, she has a sharp tongue, ignores conventions and constantly ruins his life. Now the prince's honor is on the line, and Lucien will not rest until he finds Zera's weak spot.

It is a game of cat and mouse between the one who has nothing to lose and the one who has everything. The winner will receive the loser's heart. Literally.
