Absurdist classic - that's certainly the best way to describe this book! Kurt beautifully interweaves humor with brutal realities of war, which is aided by the strange storyline of the book. Through the Tralfamadorian philosophy, he points the flaws in us Earthlings' way of living the life. As one of the characters say in the book -

"That's one thing Earthlings might learn to do, if they tried hard enough: Ignore the awful times, and concentrate on the good ones."
