In my early twenties, I read five or six of Vonnegut. I remember reading one of his short stories to a class of mine. The kids said the guy in the story was crazy. The character was a millionaire who pretended and lived the life of a poor piano player by choice.
Even though high school kids love sarcasm. Satire is another matter.
I have to confess, I don't remember what any of the books were about. I just remember they were a wild ride. Now I read so I can learn to write. I've become an even bigger book snob and critic. But my taste for a little joyful fun in a book is keener than all that deep thought from my youth. I doubt I revisit Vonnegut. But you might enjoy the ride.
Slaughterhouse Five made Vonnegut financially secure. We should all be so lucky. The book was based on his experiences in World War II. He survived the bombing of Dresden by hiding in a metal locker of a slaughterhouse as prisoner of war.
