September 1216. England is in civil war: rebel barons have invited Prince Louis of France to take the crown, while King John struggles to retain control. John summons Sir Josse d’Acquin to his side, placing Josse directly inside the conflict as French forces and English loyalties divide families as well as the kingdom.
At Hawkenlye, Josse’s daughter Meggie is called to an elderly woman who warns of catastrophe unless a dangerous mission is completed. The final Hawkenlye mystery entwines that threat with the First Barons’ War, bringing King John and Prince Louis into a story of contested kingship, divided allegiance and the legacy of the families built across the series.
