I Want to Live In a Fantasy World

I am reading a book and I think this is a true story. It is about the mother of the White Queen (who was a real person). She married a duke, so she was a lady, but she fell in love with her squire and he loved her back. So when the duke died, she ran off with the squire. It is very romantic. You should read the book. It's called The Lady of the Rivers by Phillipa Gregory.

Her ancestor was a river goddess, so there is a magical element to the book. (I don't know if that part is true.)
