I really liked the first half of this book. It was amusing, even funny at times.
I didn't like the second half too much. As soon as he mentioned the bar owner Rubinstein (Jack Ruby's real name), I knew the book would make references to the JFK assassination and the rest of the book would make assumptions that have nothing to do with historical facts.
Not on par with some of Littell's other works, but it's read by Brick and provides enough entertainment to carry the story. If you like Littell, you should enjoy it.
