the Last Boelyn by Karen Harper is not - surprise, surprise - about Anne Boleyn. It is actually the story of Mary Boleyn, the only Boleyn who survived Henry VIII's vengeance. Used as a pawn by her family at a young age to wile her way into Henry's bed, Mary is pivotal in the rise of the Boleyn family.
Amazingly, she emerges unscathed from the disastrous fall of her family, but to survive she has had to live by her wits. Refreshing to read about Mary for a change!
