Although I disagree that this is Vonnegut's best, Slaughterhouse 5 truly is an amazing, though very absurd novel. It's post-modern stream-of-consciousness sequence of events is fascinating. Billy Pilgrim, our main character, becomes unstuck in time as we are told the non-linear story of his life in a linear way. Despite the crazy plot sequence (which in and of itself is amazing), this book offers a number of lessons. Touted as the greatest anti-war book of its' time, Vonnegut presents the psychological mindfucks of war in a bizarrely entertaining way (the first corpse-mine in Dresden). So it goes. Furthermore, the Tralfamadorian concept of time is incredible and reminds us to focus on the good things in life because the negative things don't matter. Poo-tee-weet.
