Define "classic" (By age or width?)
Adventures of Tom Sawyer - Mark Twain (My first 'real' reader.)
Slaughterhouse Five - Kurt Vonnegut Jr. (Older now, high school, thought I knew everything... Oh wait, I did!)
The Hobbit/Lord of the Rings Saga - J.R.R Tolkein (Middle Earth, High Classical Literature.)
The Bible - God (Um, yeah, this is as "Classic" as it gets!)
Habitat - K. Thomas Fix (Not old, not wide, but really, REALLY good!)
