Jacquetta, daughter of the Count of Luxembourg and kinswoman to half the royalty of Europe, was married to the great Englishman John, Duke of Bedford, uncle to Henry VI. Widowed at the age of nineteen she took the extraordinary risk of marrying a gentleman of her household for love, and then carved out a life for herself as Queen Margaret of Anjou's close friend and a Lancaster supporter - until the day that her daughter Elizabeth Woodville fell in love and married the rival king Edward IV. Of all the little-known but important women of the period, her dramatic story is the most neglected., With her links to Melusina, and to the founder of the house of Luxembourg, together with her reputation for making magic, she is the most haunting of heroines.
