I read Harry Potter...I don't usually read series...and I've been listening more to books on tape as my eyes were out faster and faster.
I like the classics, like, Of Mice and Men (John Steinback), Animal Farn (George Orwell), Les Miserabe was too wordy, but decent (Victor Hugo), All Quiet on the Western Front (Erich Maria Remarque), The Stranger (Albert Camus) there are more...
The Rapture of Canaan (can't remember) is one of my favorite books!
Angela's Ashes (Frank McCourt) is also really good.
I'm working on 1984 (George Orwell) right now.
