Daughters of the formidable Isabella and Ferdinand of Spain, Katherine and Juana were born in to a world of privilege and luxury that came at a devastating personal price. They were trained from an early age to understand European diplomacy and to revere their position as defenders of Catholicism against any threat to their religion. In an age of familiy politics, the sisters were useful only as a way to secure new alliances through marriage; both at the mercy of the men they were to marry. Katherine's marriage to Prnice Arthur apeared to go well until he died suddenly after ten months. Marriage to King Henry VIII did not result in the vital heir, and soon Henry was displaying his despotic nature, with the execution of 'traitors' and high-handed affairs. Juana fared no better with Philip of Burgundy, whose naked amibition and cruelty made her life equally difficult. Julia Fox's new biography vividly portrays the harsh realities of being a queen within a world dominated and run by men. She provides a fresh take on the sisters' characters and interior worlds by setting them within their family and Spanish contexts. In the case of both women, this vibrant biography graphically illustrates the dangers of being a royal commodity at such a perilous time, and gives a highly revealing portrait of two forceful female personaliites thrwarted by the men around them - including the men closest to them who sould have cared for them the most.
