Back in the day you couldn't read Slaughterhouse Five. Let's keep this in perspective what are Snow White Cinderella, Peter Pan etc? All fairy tales and involved magic. These Harry Potter books are good escape and if a child wanted to read a 800+ page book and be interested then so be it. It is better that Heather has two mommies or Daddy's roomate. Just something to think about.
Hans Christian Andersen and the Brothers Grimm ... Agents of Satan.
