Philippa Gregory's latest in the Plantagenet/Tudor series tells of the pivotal roles the three queens played in Henry VIII’s kingdom. Katherine of Aragon arrives at the Tudor court as a young bride, the oldest princess, Margaret, who serves as the narrator, takes her measure. 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, since they will become the queens of England, Scotland, and France. Although they are tied by family loyalties and affections, the three queens find themselves set against each other. Katherine commands an army against Margaret and kills her husband James IV of Scotland. But Margaret’s boy becomes heir to the Tudor throne when Katherine loses her son. Mary steals the widowed Margaret’s proposed husband, but when Mary is widowed it is her secret marriage for love that is the envy of the others. This was an interesting introduction into the events of the time from a woman's perspective and well worth a read.
