The Reluctant Queen — Molly Costain Haycraft

Doomed by her royal blood to be Henry VIII's pawn, his sister, Mary Tudor, was England's beloved princess. Mary rebelled against being used in Henry's international game of power, but was pledged first to the dreary, young prince of Flanders and then to the feeble, old king of France. Mary risked death and dishonor as she braved Henry's wrath in order to be with the dashing Charles Brandon, a man far beneath her station, but greatly loved by Mary.

A novel for teens about Henry VIII's sister Mary Rose, forced to marry the King of France although she loves the handsome Duke of Suffolk.
