In my opinion this is a literary masterpiece.
The genius of the writing, where reality and the book blur, is something I've never experienced in a book before. I was taken on a mental trip where reality seemed unstable for a moment. On the back of the book, the New York Times has said "Vonnegut performs considerable complex magic...he very nearly levitates", and I couldn't agree more.
The book is about Dwayne Hoover car salesman, all-round respected guy, his descent into madness and his eventual meeting of the great science fiction writer Kilgore Trout. I'm not sure how much else I can tell you about it without giving too much away.
I recommended this to a friend, and he read it, next I knew he was then searching for more Vonnegut books, exactly as I had done many years ago when a friend of mine lent me Welcome to the Monkeyhouse by Vonnegut.
If you haven't read anything by Kurt Vonnegut Jnr, then you have missed a truly great modern writer. Welcome to the Monkeyhouse, God Bless you Mr Rosewater, Jailbird, Cat's Cradle, the Sirens of Titan and many others, get one read it, procure more...
