A Million Miles Ago

Sophia decides to die. She is not sad, or sick or lonely, she is simply done. As luck would have it though, she doesn't take her last breath but descends upon a small town, in a coma, with only a notebook and a picture. Who is she? Why does she want to die? This small town will never be the same after finding out her story and willing her to stay alive. But is that what she would want?
