Her parents had lost a crown before she was born. At seventy, Sophia of Hanover was named in the law that would decide who wore another. She almost lived long enough to wear it herself.
Margaret Tudor reached her brother's border heavily pregnant and was told to wait. The queen of Scotland could not step into England until Henry VIII said she could.
Elizabeth I never charged her. Never tried her. Never explained. She simply decided that a girl born with royal blood was too dangerous to be free, and Arbella Stuart spent thirty years learning what that decision felt like from the inside.
She crossed into England in a fishing boat at twenty-five and wrote to her cousin asking for help. She would not leave for nineteen years. She would not leave alive.
She exchanged rings with a man in secret and Henry VIII put him in the Tower. He died there. She walked out and went back to court and spent the next forty years reaching for the crown that had killed him.
