In the moon-blessed Northern Moon City-State, destined saintess Leona has shared eight years of sacred covenant with Archon Ashe—only to be betrayed on the night of her anointment, when Ashe brands a moon-seal upon her cousin Viola's neck and Viola secretly forges the moon-prayers to steal the sainthood. Leona publicly incinerates every memento of their bond and walks into the sacred Laurel Grove to undergo the Oath-Forsaking Rite: confronting the scalding truth, enduring silver moonfire purification, and severing the covenant's entwined lock of hair with a ritual blade. On the verge of collapse, she is carried away by Cain Thorne, the unchained Moon-King of the wilds, who offers not possession but an alliance of equals—two half-gods standing shoulder to shoulder against all enemies. Set against a Greek-mythological backdrop, the story explores the betrayal of love and power, and the fierce battle for self-ownership: the truest crown is never bestowed, but seized by the one who dares to rewrite her own fate.
