Her name means "gentle." Everyone believes it. That's the point.Hann Rou helped win her adopted brother's throne from the shadows: nine rival princes, one crown, and a war she fought with information instead of blades. Now he sits on it, and he has decided she has grown too dangerous to keep alive.Married off to a Prince Consort whose ambitions her title legally ends, mourning a child she lost and never speaks of, Rou builds the one thing no one thinks to watch: her own household. Behind its walls, she trains the concubines she's "generously" gifted her husband, cultivates a network that reaches the Empress Dowager's oldest loyalists, and, one careful exchange at a time, makes sure that the children born inside her palace answer to her first, and the throne second.The Emperor is hunting a threat. He doesn't know he's already lost.
