London, 1649. Horrified eyewitnesses to King Charles's bloody execution, Royalists Nan Wilmot and Frances Apsley plot to return the king's exiled son to England's throne, while their radical cousin Luce, the wife of king-killer John Hutchinson, rejoices in the new republic's triumph. Nan exploits her high-ranking position as Countess of Rochester to manipulate England's great divide, flouting Cromwell and establishing a Royalist spy network; while Frances and her husband Allen join the destitute prince in Paris's Louvre Palace to support his restoration. As the women work from the shadows to topple Cromwell's regime, their husbands fight openly for the throne on England's bloody battlefields.But will the return of the king be a victory, or destroy them all? Separated by loyalty and bound by love, Luce, Nan and Frances hold the fate of England—and their family—in their hands.A true story based on surviving 400-year-old diaries of Elizabeth St.John's family.
