Slaughterhouse-five ; The sirens of Titan ; Player-piano ; cat's cradle ; Breakfast of champions ; Mother night

It started off as a fun and weird scifi book, to a fun and cynical take on the human condition, to a beautiful take on the meaning of life. One of Constants last lines on Titan made tears come to my eyes.

Edit: The more and more I think on it the more I like this book. I will definitely be reading it again at some point.
