1514. Henry VIII decides to marry his sister Mary to Louis XII, the elderly King of France. Accompanying Mary to her wedding is her cousin, seventeen-year-old Elizabeth Grey.

Despite a magnificent reception in Abbeville, not everyone at the French court welcomes the English bride. Some, like Madame Louise, mother of Louis's heir, would like to see Mary dead. But it is Louis who dies and Elizabeth who must twice put herself in danger to save her cousin. Just when all seems lost, Mary finds a path to personal happiness. But her choice comes at a price and it is not only Mary who must pay.

From the menacing world of the French court and the glittering extravaganza of the Field of the Cloth of Gold to the tinder box that is Tudor Ireland, The Mirror of Naples is a story of the enduring power of love and the cost to a young woman of having what she wants.
