Kateryn Parr, a thirty-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.

Kateryn has no doubt about the danger she faces: the previous queen lasted sixteen months, the one before barely half a year. But Henry adores his new bride and Kateryn's trust in him grows as she unites the royal family, creates a radical study circle at the heart of the court, and rules the kingdom as Regent.

But is this enough to keep her safe? A leader of religious reform and the first woman to publish in English, Kateryn stands out as an independent woman with a mind of her own. But she 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...

From the bestselling author who has illuminated all of Henry's queens comes a deeply intimate portrayal of the last: a woman who longed for passion, power, and education at the court of a medieval killer.
