And when Jane refused to convert to Catholicism, Mary sentenced her to death. “Learn to die,” Jane advised her younger sister Catherine.

Having witnessed the death of sisters who betrayed the trust of the queens, Mary is aware of the threat looming over her, but intends to decide her own destiny. What happens when the last of the Tudor line betrays her wayward and cruel august cousin?
