This is a book by Kurt Vonnegut. It is a good book and a lot of fun to read and quite short in length too. Perfect travel partner.
Here is a wikipedia link to book and it says more than I can, better than I can, http://en.wikipedia.org/wiki/Slaughterhouse-Fiv
I give it 4 star rating.
His biography, which I read a couple of years back is even better. Perhaps you can find it on the internet.
