Vonnegut is fantastic at what he does, and that is use humor and a knife's edge balance of cynicism and innocence to hold a mirror up to our world for us, and show us how ridiculous everything has gotten. Hocus Pocus was no exception - in fact, it was almost more pertinent than anything of his I've read since Slaughterhouse Five, as the world that the narrator is writing in is a world that ours has become dangerously close to (foreign investors own just about everything in the US, aircraft carriers have been converted into prisons, the Freedom of Information Act has been repealed, so on and so on).
The narrator was equal parts funny and tragic, likeable and unlikeable. He was a man that tried to do what he could with what he had, and the story he shares is about how that all went both awry and right on track. Any fan of Vonnegut will like Hocus Pocus, and may even love it. It was another great book by a great author.
