In the twelfth year of Jian'an, Guo Jia died of illness on the northern campaign route. He left behind not only the legendary bond of mutual recognition he shared with Cao Cao, who said, “The man who will help me accomplish my great ambitions must be this one,” but also a daughter he had never mentioned to anyone: Guo Wan.
Seven years later, a young woman carrying her father's unfinished letters slips into Ye under Sima Yi's protection and at his behest. She thinks she is the one moving the pieces, but before long, she becomes the most crucial pawn in the struggle between rival powers. As the predictions Guo Jia left behind come true one by one, Wan'er discovers there are unanswered questions surrounding her father's death. How will this girl, who seeks to navigate a world in turmoil through her wits, face the treacherous currents at court, more perilous than any battlefield, and decipher the final character her father left unwritten?
