I can't read. In fact, I don't even know how I'm typing this sentence. If I could read, these would be my favorites, in no particular order:
The Brothers Karamazov, Crime & Punishment, Notes from the Underground (and most Dostoyevsky)
The Magic Mountain, Buddenbrooks (Thomas Mann)
Steppenwolf (Herman Hesse)
The Stranger (Albert Camus)
Nausea (Jean-Paul Sartre)
Things Fall Apart (Chinua Achebe)
Thus Spoke Zarathustra (Nietzsche)
American Psycho (Bret Easton Ellis)
Portrait of the Artist as a Young Man, Ulysses (James Joyce)
My guilty pleasure reading is Tom Clancy.
The Stranger was messed up. the guy just needed to be diagnosed with a psych disease.
