England teeters on the edge of chaos, and salvation may come at a price.

Left in political and personal limbo, Katharine of Aragon languishes in forced poverty at the court of King Henry VII, praying for deliverance. When word arrives that her sister, Juana of Spain, has been shipwrecked on English shores with her powerful husband, Philip of Burgundy, Katharine believes her prayers have been answered. Juana is en route to claim her birthright, the crown of Castile, after the death of their mother, Queen Isabella of Castile, and Katharine is certain her sister will either take her home or speak on her behalf.

But Philip has his own ambitions. As tensions rise between Spain, Burgundy, and England, Katharine becomes a pawn in a larger game, one that may decide the fate of Europe itself. A chilling discovery rocks the Tudor court. A fresh threat from Edmund de la Pole, the exiled Duke of Suffolk, suggests that his long-rumored plot to overthrow the Tudors is finally in motion. With England's fragile peace hanging in the balance, the king's ruthless enforcer, Sir Thomas Lovell, is tasked with uncovering the truth. What he finds is a conspiracy steeped in treason, deception, and ambition—a plot that could shatter everything Henry VII has built and plunge the realm into civil war. As old enemies return and new alliances are tested, can Lovell stop Suffolk before history is rewritten? Or will England's crown fall to another Pretender?

Treachery, international power struggles, and royal secrets collide in this gripping conclusion to The Tudor Throne series—perfect for fans of Philippa Gregory, C.J. Sansom, and all lovers of rich Tudor-era historical fiction.
