Catch 22.
Funniest book ever written. The way everything turns in circles is incredible.
Young American soldier: "Don't you know it's better to die on your feet than live on your knees?"
Old Italian brothel owner: "You're so young. It's better to live on your feet than to die on your knees."
The ragged trousered philanthropists
The book that nearly started a revolution in trenches of WWI.
It puts forth the argument for socialism and is a heart wrenching picture of the working classes in the early 20th century.
Trinity
I'm not sure why I love this book so much. Maybe because it clarifies the rift in Ireland to some extent. Maybe because the main character struck me as a true hero. I think it was the first book I ever read that ended in the way it ends.
Foucault's pendulum
Best ending I've ever read. And it's such a piss take on conspiracy theories it's classic.
Lord of the rings
Beautifully written and a must for every fantasy gamer in the whole wide world. The novel upon which most other fantasy novels are based and never bettered.
