Mistress of the Monarchy ─ The Life of Katherine Swynford, Duchess of Lancaster

Acclaimed author Alison Weir brings to life the extraordinary tale of Katherine Swynford, a royal mistress who became one of the most crucial figures in the history of Great Britain. Born in the mid-fourteenth century, Katherine de Roet was only twelve when she married Hugh Swynford, an impoverished knight. But her story had truly begun two years earlier, when she was appointed governess to the household of John of Gaunt, Duke of Lancaster and fourth son of King Edward III. Widowed at twenty-one, Katherine became John's mistress and then, after many twists of fortune, his bride in a scandalous marriage. Mistress of the Monarchy reveals a woman ahead of her time—making her own choices, flouting convention, and taking control of her own destiny. Indeed, without Katherine Swynford, the course of English history, perhaps even the world, would have been very different.

Alison Weir is the New York Times bestselling author of the novels Innocent Traitor and The Lady Elizabeth and several historical biographies, including Mistress of the Monarchy, Queen Isabella, Henry VIII, Eleanor of Aquitaine, The Life of Elizabeth I, and The Six Wives of Henry VIII. She lives in Surrey, England with her husband and two children.
