I have so many!!!! I usually go for writers more than just books. I like most of Stephen King - I especially love The Green Mile, It and Desperation. Jeffrey Deaver and James Patterson are among my favourites too.
Favourite books, as in stand alone books are: To kill a mockingbird, Ordinary People, The Hobbit, Dr. Phil (well, I think he's good!!), The mayor of Casterbridge.

There are so many more, just can't think at the moment... it's too early here...
