Totally blanked on Bram Stoker - got Shelley in my head for Frankenstein and she just wouldn't go away. Had no idea who Lannister was, or who wrote Bridget Jones Diary since I've never read either of them.
Enjoyed the quiz, but it really could use a yellow box. Probably would have gotten 12 or so without reading a clue just by typing in the best known authors.
