What story does anna tell about her sister in my sisters keeper?

She tells about how she was dying and she was born to donate bone marrow and whatever else her sister needs, she loves her sister but she wants free will of her own body so she tells about suing her parents for body emancipation. Her sister agrees with her and she ends up able to! I hope this helps

go to crash course lititure and go to seconed page and it shows a video about that
