The Countess was a dame

If you have a weakness for historical romances and saucy women you won’t want to miss The Countess and the King: A Novel of the Countess of Dorchester and King James II by Susan Holloway Scott. Katherine Sedley never had a chance to have a conventional life. Her mother was a mad aristocratic and her father was an infamous libertine. Luckily for her she was a wise, witty beauty. Katherine passed up marriage for a love affair with Duke of York. She remained his mistress after he became King James II. Her life was tumultuous and remarkably lucky. It is a riveting tale of a woman who called her own tune and outlived her enemies to dance to it. 

The famous Mitford sisters are descended from Katherine, The Duchess of Dorchester.
