The Book That Changed My Life
Stephen King is the best selling author of over 40 books. Including The Shining, The Green Mile, The Stand and Carrie. Many of his stories have been turned into screenplays for both movies and television.
Lord of the Flies by William Golding, because it is both a story with a message and because it is a great tale of adventure. My advice about reading is to do a lot of it - those make-believe worlds are the best worlds I know.
