The Long Walk by Richard Bachman (Stephen King's pseudonym). I've probably read it 10 times. It's so engrossing and just fun to read. Basically, teenage boys in a dystopian society are competing in the "long walk" - basically all the contestants walk until they die, and the last one standing wins. The amount of psychological horror the main characters go through is fascinating, and the contrast between the psychological horror between them and the onlookers is interesting to think about.
I love all the classics and I try my best to understand Cormac and Vonnegut and Bukowski but King will always have a special place in my heart. Read The Shining at ten years old and never looked back. The Stand should be on every school summer reading list and his magnum opus The Dark Tower is one of the greatest adventures I've ever had. If you've never read King I suggest you get out from under that rock and read his collections of short stories, Night Shift and Four Past Midnight. Different Seasons is a collection of four novellas and is fucking beautiful. I read every King he put out throughout my youth and his books (along with Calvin & Hobbes) taught me everything about life they don't teach in a classroom.
Oh most definitely. Besides Fight Club I loved Rant and Invisible Monsters. His short stories are great too. I thought Zombie hit it hard.
