"The Hobbit" from J.R.R. Tolkien of course and "The goblet of fire" from J.K. Rowling once again(I lost count), yes I read multiple books at the same time^^.
I'm a fan too. I have read till The Order of The Phoenix. I enjoyed The Goblet of Fire very much. That's where I got to know who Dumbledore really is. The Movies don't give much justice to the story so I would recommend you read them first before watching the movies if you haven't and are thinking along those lines
