“There is only one bond that I trust: between a woman and her sisters. We never take our eyes off each other. In love and in rivalry, we always think of each other.” When Katherine of Aragon is brought to the Tudor court as a young bride, the oldest princess, Margaret, takes her measure. With one look, each knows the other for a rival, an ally, a pawn, destined – with Margaret’s younger sister Mary – to a sisterhood unique in all the world. The three sisters will become the queens of England, Scotland and France.
