Kateryn Parr, a 30-year-old widow in a secret affair with a new lover, has no choice when a man old enough to be her father who has buried four wives --- King Henry VIII --- commands her to marry him. Despite being a leader of religious reform and the first woman to publish in English, Kateryn cannot save the Protestants, under threat for their faith, and Henry’s dangerous gaze turns on her. The traditional churchmen and rivals for power accuse her of heresy. The punishment is death by fire, and the king’s name is on the warrant.
