The Kingmaker's Daughter by Philippa Gregory (2013)
The main character is Anne, the kingmaker's daughter. Her father raised the royal York boys Edward, George and Richard, and when he didn't like the way Henry (the sleeping king, as Anne calls him) ruled, he placed Edward on the throne, imprisoning Henry. When he didn't like the fact that Edward's wife and her family had too much influence on him, he tried to put the second son George in his place, but lost that bid.
Anne's sister is married to George, at 15 Anne gets married off to old King Henry's son, her father thinking he can get one of his daughters on the throne and be grandfather to a king. Then Anne's young husband and her father get killed in battle. She ends up marrying Richard, the third York son. Her nemesis - real or imagined is King Edward;s wife Elizabeth Woodville, who is not only beautiful and fertile with 10 children, but skillful in getting her family into positions of power.
Oh, the constant machinations and bids for power, trying to disprove the rights of one or the other to be king or queen, calling marriages illegal, children bastards, praying for a male child, trying to rule through children, accusing people of bewitching them. And this struggle for power, at least through Anne's eyes, doesn't mention how one or the other could be a better ruler for the country, but who can hold the most elaborate Christmas feast or wear the most elegant dresses with silks, gold, and furs.
At times this all sounded so petty, but then we have our own ways of being petty, and I don't even want to start with the power plays in American politics. Even today we follow the lives British royalty - Princess Charlotte was just born to Prince William and Kate. I'm not clear who will be king after Queen Elizabeth, I've read that she will pass the throne on to Price William or maybe her son Prince Charles this year.
I think I have had enough of a dose of British royalty for a while, but it is an interesting read, especially the details of daily life.
