Shen Zhiwei, the cast-off daughter of the prime minister’s household, transmigrates back into her twelve-year-old self, armed with memories of her past life and a military talisman atlas. She lies low amid the powerful and well-connected. Using the insight of a child to plan her moves, she relies on Northern Frontier General Xie Linchuan to tear open the court’s dark secrets, aided by secret edicts from female historian Su Yanqiu and the hidden blade of Bai Zhao, a mute girl. Her jealous half-sister Shen Zhaohua and the calculating He Yanzhi, son of a minister, become stepping stones on her rise to the top. Revenge is not what she wants: she means to reshape this kingdom that devours its people. From cast-off daughter to regent, she writes a history of emperors in the blood of women.
