13 year old Anna Fitzgerald is the main character of this story. As stated in the summary, she was genetically engineered to save her sister, who has cancer. Anna is intelligent, witty, and awfully sarcastic. Anna feels as if she if selfish for filing a lawsuit against her parents, knowing that she still has to save Kate. Anna goes through a lot of tough decision making throughout the story, and starts to doubt herself more and more. She kept trying to decide whether or not she was doing the right thing by filing this lawsuit against her parents, but eventually stuck with wanting medical emancipation rights as a minor. Anna cares both about Kate and herself. She's afraid of public speaking, until she told the story of why she first started to file this lawsuit (to find out why, look on Kate's page). In the end, Anna ends up dying in the tragic car accident involving herself, Campbell Alexander and his service dog.
