1984 by George Orwell - Probably my favorite book, I found it very well written, made my already existing paranoia even more severe =)
Johnny Got His Gun by Dalton Trumbo - Was a bit confusing time to time, but also a wonderful book really enjoyed reading it, until the end, then I felt horrible...
The Giver by Lois Lowry - Was interesting when I read it, though that was in 7th grade and barely remember any of it now, aside that I really enjoyed it.
Brave New World by Aldous Huxley - I think 1984 was a lot better, but I usually hear B.N.W. and Fahrenheit 451 are better, I don't think personally.
I read all those books when I was younger, except 1984, I kept re-reading it, and am trying currently if I can find the time to.
Looking forward to The Marriage of Heaven and Hell by William Blake, and The Doors of Perception/Heaven and Hell (combined) by Aldous Huxley
