A Philippa Gregory novel

I just finished Philippa Gregory's "The White Queen." She is great at Historic fiction and I'm a great fan of hers. This novel was about the War of the Roses or the Cousins' War in the mid to late 1400's. King Edward has won the throne away from the White Rose Lancastarians. He meets and marries Elizabeth Woodville, a widow with two sons. They marry in secret till he is sure of his reign. Their rule is rocky. Constant fighting to maintain the Red Rose rule. At Edward's death his son, Edward, is to become king with King Edward's younger brother, Richard, acting as regent until 12 year old Edward comes of age. Richard declares himself king and young Edward disappears. To this day, no one knows what happened to King Edward's sons. The story ends with Henry Tudor making his return to England to battle for his rightful place as king. Gregory does a great job of filling in the missing pieces even though they are fiction. This is the first of a new series set amid the deadly feuds of England.
