The Constant Princess by Philippa Gregory was published 2005.
A highly fictionalized version of the life of Catherine of Aragon and her rise to power in England.
My fear is that history is boring. That royal intrigues are boring.
Not so in the case of this book. It’s very fast paced. Most entertaining.
It’s part of what the author calls the The Plantagenet and Tudor Novels.
Though Philippa has a PhD in history, another of her books seemed to me more Romance / Bodice ripper.
The Other Boleyn Girl (2001) was not as good, IMHO.
The other Boleyn girl.
In fact, Mary was the king’s mistress while Catherine was his wife. Though little of accuracy is known about Mary, she did have a roller coaster of a life. Mary died aged 43–44.
King Henry had Anne beheaded at the Tower of London at age 28–35.
In any case, if you like historical fiction — check out Philippa Gregory.
