Dracula would be mine I think. I love the style in which it is written. It's very atmospheric, especially the captain's log from the Demeter, that's followed by a newspaper article describing how the ship came into Whitby harbour with the dead captain bound to the helm.
I must confess though, I can not stand Stephen King. I've read "IT," and part of "Dreamcatcher," but I had to give up on the later because it just stopped making sense with all that Mr Gray stuff. His stlye of writing seems to contain too much gratuitous swearing and violence...I'm not saying I found that offense: I didn't, but it annoys me when it adds nothing to the plot or characters. It just seems to be used to shock people into reading. He's only getting one more chance from me; maybe the next one will be better.
Having said that, I've never tried any of his non-horror work. The Shawshank Redemption is a fantastically moving film, so I won't dismiss him from my bookshelf yet. Also, to this day I am still scared of clowns, so maybe IT was a better book than I'm giving it credit for
