I had such a love/hate relationship with this book, and yet I found I could not put it down. It's a bona-fide train wreck, full of gimmicks like the drawings that seem to have little import, and breaching of taboos largely for shock value, but buried beneath all that is a compelling message, delivered in a truly original way, and I am still processing it. Vonnegut has some interesting things to say about free will, but I think he let himself get carried away in the process.
