This is the story of how one woman changed the balance of power in Western Europe, by divorcing one man and marrying another. Eleanor of Aquitaine is the Queen of France, but has been alienated from her husband. Her campaign for an end to that marriage led to a shocking remarriage with a much younger man, and the beginning of the Plantaganet dynasty in England. Along the way we discover why our favorite tales of knightly romance, from Lancelot and Guinevere to Tristan and Isolde, are connected to Eleanor and her enormous influence.
