Acclaimed historian Giles Tremlett chronicles the life of Isabella of Castile as she led her country out of the murky middle ages and harnessed the newest ideas and tools of the early Renaissance to turn her ill-disciplined, quarrelsome nation into a sharper, modern state with a powerful, clear-minded, and ambitious monarch at its centre. With authority, insight and flair he relates the story of this legendary, if controversial, first initiate in a small club of great European queens that includes Elizabeth I of England, Russia's Catherine the Great, and Britain's Queen Victoria.
