it is a looong book if you try to read that before friday u gonna get one of those 'harry potter headaches'...just read it at your pace and go see the movie whenever it's not like it won't be out on DVD as soon as they can get it.
I believe it is 721 pages. You could read it if that is seriously all you do all week. You can try but I doubt you will finish, I know I wouldn't be able to.
