The Kingmaker's daughter

Richard Neville, Earl of Warwick, is the most powerful magnate in fifteenth century England, instrumental in putting the kings of England on the throne. Without a son and heir, he uses his daughters, Anne and Isabel, as pawns in his political games, which include seeing one of his daughters become Queen of England. Isabel is married to George, King Edward's brother and Anne is married at fourteen and is soon widowed and fatherless. She then takes her own life in hand and marries Richard, Duke of Gloucester, King Edward's other brother, who eventually becomes Richard III. Her choice costs her the life of her only son, Prince Edward, but she does become Queen, thereby fulfilling her father's wish.
