Because she cannot refuse ... 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.
