It’s midwinter in 1539, and Catherine Havens Overton has just given birth to her second child, a daughter. The convent in which she was raised is now part of the Overton lands, and Catherine’s husband William owns the properties that once belonged to her mother’s family. With a son, Robert, and her new daughter, Veronica, Catherine’s life as the mistress of a great household should be complete.

Henry VIII’s England has not been kind to many of the evicted members of religious houses, and Catherine has gathered about her a group of former nuns in hopes of providing them a chance to serve in the village of Havenston, her City of Ladies. Catherine’s own past haunts her. Her husband suspects that Catherine’s son is not his child, and his ambitions lie with service at court. Then the women of Overton House begin to disappear, and though one of them is found brutally murdered nearby, William forces Catherine to go to Hatfield House, where the young Elizabeth Tudor lives, to improve the family’s standing—and to ensure, for her own safety, that she is as far away from connections to her old convent as possible.

Reluctantly, Catherine obeys, only to find herself serving not only the Protestant Elizabeth but also the shamed Catholic Mary Tudor. As the murders in Yorkshire mount up and her loyalty to the Tudor sisters grows more complicated, Catherine must uncover the secret of the killer and keep her dream of a City of Ladies alive.
