Ning Ruxin swore an oath at her dying mother’s bedside: never marry, but have a child — secure one anchor of blood in a world of treacherous men. She sets a single, cold goal: find a suitable father, seize what she needs, and leave. When the reserved, iron-faced captain Fu Kuoji rescues her from the street, she engineers a plan to become his child’s mother by any means necessary. She fakes helplessness, plays servant, drugs him once — twice — but fate refuses to be that simple. Kuoji is not only formidable on the battlefield; he sees through her tricks, keeps secrets of his own, and refuses to be used. When she finally carries his child, she discovers a deeper betrayal: a housemaid who calls him “husband,” a hidden son, and a network of lies built to protect duty and honor. Ning chooses the path her mother commanded — but on her terms. She will take the child, take the wealth, and take power. She will outwit conspirators, punish those who tried to bury her child, and master the one weapon every abandoned woman in Liangdu learns to wield: independence. As Fu Kuoji falls into a slow-burning obsession, Ning becomes the city’s richest, most untouchable woman — the white moon that haunts him while she lives free, with her son and her empire. Who gets the final name written beside the child’s? Who owns the right to love? And can a woman who swore never to love find anything but triumph in her bargain?
