Ah, books. I love summer just because I finally get the chance to read again!
I enjoyed 1984, but since last year, I am just more partial to 1983...

ok, down to business.
Survival in Auschwitz - Primo Levi: Thought provoking story about a chemist thrown into the death camp at Auschwitz and how he survived
The Fountainhead - Ayn Rand: Given to me by a teacher, and good friend. It impacted him when he read it in high school, as well as another teacher from my school. They both recommended it when I was going through a rough time last year. Very good book.
Rocket Boys: Classic
I, Robot - Isaac Asimov: Haven't finished yet, but was given to me by another favorite teacher for graduation a couple weeks ago. I am really enjoying it.
Lies my Teacher Told Me - James Loewen: The stuff you were never told about American History
The Jungle - Upton Sinclair: Interesting author, thought provoking book that had the opposite affect that the author had in mind
Cold Mountain - Charles Frazier
Thirteen Moons - Charles Frazier: Great author, both meaningful books. The first about a man and woman separated by the Civil War. Her struggle to keep her father's farm, and his experiences after ditching the war and trying to walk home. Thirteen Moons is about a man's life, from orphanhood, to fame and fortune, all the while trying to do best by the world and himself.
Red Badge of Courage - Classic
That's pretty much all I've got for now... I am definitely going to be reading some of the other books posted in this thread. I am excited!
OH! I almost forgot!
Self Reliance - Emerson
and pretty much anything else from the Transcendentalists. They are pretty inspiring and thought-provoking. It is also pretty interesting to compare them to the hippies. Some of the similarities are quite remarkable.
