Gregory, Philippa. Plantagenet and Tudor novels

Series statement from philippagregory.com

Her secrets shaped a kingdom. Her loyalty was deadly. Jane Boleyn watches from the shadows of the Tudor court, where nothing is more powerful than a secret. And power rests on the edge of a tyrant king's sword. She wears many masks--loving wife, devoted sister, and obedient spy. It's what a woman must do to survive. The only weapon she has is her voice. They say Jane's whispers sealed the fate of two queens. They called her a liar and a traitor. But the truth is far more dangerous
