I've read all of the books. took me 4 days just to read Deathly Hallows. I stood in line for 5 hours, at midnight at Barnes and Noble, to get that book. I still can't believe I did that, but that was my FIRST experience doing that. It was fun to see all the costumes. Alas, my book was not one of the 1st editions, sorry.
My fav book and movie in this series is Goblet of Fire. Why? because it was totally unexpected that Harry was chosen as one of the champions. (Also because David Tennant played evil Barty Crouch jr so....evilly!!) I loved the maze, the special effects, the funny hats at the world cup-- and of course the magical tents. Oh, and Robert Pattinson (Cedric) was a dream. Need I say more?
Oh, yes.....I was introduced to the HP series thru a friend, when we both went to see Prizoner Of Azkaban movie. THEN I started reading the books from the beginning and then I got the movies.
