In the mood I'm in at the moment, my top five are.....
Animal Farm ~ George Orwell
Nineteen Eighty-Four ~ George Orwell
The Picture of Dorian Gray ~ Oscar Wilde
Moving Pictures ~ Terry Pratchett
Ginger Geezer: The Life of Vivian Stanshall ~ L. Randall & C. Welch
Come tomorrow morning, though, and this list would have changed.
