Eleanor of Aquitaine, Queen of England and France, travels to Castile in the company of her friend and confidant, the Druid Blédhri, who wants to leave a written record of the queen's eventful life. The journey is long and tedious, but nothing daunts the great queen, who has had to deal with all manner of difficulties and dangers in order to fulfil the mission that fate and her iron will have set her: to be the Lady of Europe. During her travels Eleanor looks back on her life: her marriage, her difficult relationship with and divorce from Louis VII of France; her marriage to the Plantagenet Henry II, the Second and Third Crusades, the lives of her children and stories from her life. Ara Antón introduces readers to the fascinating but harsh Middle Ages, its continuous struggles and political conflicts, in a land of deeply rooted customs.
