I read the first six Harry Potter books in Braille. Between the release of the sixth book and the final book I went back and listened to them as audio books, and my perception changed just enough to make me appreciate characters from a new perspective. I am a traitor and love the narration from an American guy over Jim Dale.
In fact, in so far as you're taking reader requests, I would love an analysis on Snape and other characters whom we grow up thinking should be villains, or characters who may've been misunderstood.
Another reader request: Please write an article devoted to books HP fans should read next!
