It was, from the start, a dangerous experiment. Charles I of England was a Protestant, the fifteen-year-old French princess a Catholic. The marriage was arranged for political purposes, and it seemed a mismatch of personalities. But against the odds, the reserved king and his naively vivacious bride fell passionately in love, and for ten years England enjoyed an era of peace and prosperity. When Charles became involved in war with Puritan Scotland, popular hatred of Henrietta's Catholicism roused Parliament to fury. As the opposition party embraced new values of liberty and republicanism--the blueprint for the American War of Independence and the French Revolution--Charles's fears for his wife's safety drove him into a civil war that would cost him his crown and his head. Rejecting centuries of hostile historical tradition, prize-winning biographer Katie Whitaker uses a host of original sources--including many unpublished manuscripts and letters--to create an intimate portrait of a remarkable marriage.

Margaret Cavendish's life as a writer and noblewoman unfolded against the backdrop of the English Civil War and Restoration. Pursuing the only career open to women of her class, she became a lady-in-waiting to the Queen Henrietta Maria. Exiled to Paris with the Queen, she met and married William Cavendish, Marquis of Newcastle. In exile, Margaret did something unthinkable for a seventeenth-century Englishwoman: she lived proudly as a writer. Eventually she published twenty-three volumes, starting with "Poems and Fancies," the first book of English poetry published by a woman under her own name. But later generations too easily accepted the disparaging opinions of her shocked critics, and labeled her "Mad Madge of Newcastle.""Mad Madge" is both a lively biography of a fascinating woman and a window on a tumultuous cultural time.
