The story will make your heartbroken. I know there a movie called the same thing but the ending has changed from the books ending. If you watched the movie before reading this book your are going to get surprise ending either way but especially by the book ending.
Anna doe go to court hearing to get a medical emancipation from her parents. You see how each member of the family is suffering from her older sister Kate illness. It is something you should have tissures around for it a bit sad. You also start to understand the movie a bit but I really like the book better then the movie. Though I was shock to see what sister dies in book.
