Ren Daiyan was still just a boy when he took the lives of seven men while guarding an imperial magistrate of Kitai. That moment on a lonely road changed his life--in entirely unexpected ways, sending him into the forests of Kitai among the outlaws. From there he emerges years later--and his life changes again, dramatically, as he circles towards the court and emperor, while war approaches Kitai from the north.
Lin Shan is the daughter of a scholar, his beloved only child. Educated by him in ways young women never are, gifted as a songwriter and calligrapher, she finds herself living a life suspended between two worlds. Her intelligence captivates an emperor--and alienates women at the court. But when her father's life is endangered by the savage politics of the day, Shan must act in ways no woman ever has.
