I read everything Stephen King puts out. He doesn't single any particular religion out but he uses things in every day life in his books. He is smart and very aware so it doesn't shock me that he writes and uses everything around him in the world.
His home in Bangor is surrounded by a beautiful fence with spiders and webs and different things on it. It would shock me if a witness actually tried to go up to the house. It looks scary and given what he writes I am sure they are already afraid of the "demon".
King is an amazing gifted writer and I can't wait for his next book!
