Louise-Franciose La Baume Le Blanc de la Valliere
It takes a few years, but eventually Petite's mother marries a Marquis and gets Petite a place at court as a lady-in-waiting. There she captures the eye, and heart, of young King Louis. Their affair catapults Petite from the heights of happiness to the deepest of grief. The years they spend together are the formative years of Louis as King, he repairs the damage done to the country by corrupt officials and France becomes prosperous and wealthy once more. The couple have four children together. Through it all, Petite is haunted by the memory of the white horse, guilt over the death of her father and her belief that she was cursed by her long-ago spell.
