The prose is very good. It's as good as the writing in that kind of book which has to survive on its style alone, because not too much happens - but this is a book with interesting content too. It also helps that it covers a lot of subjects I am interested in, and have read about before. I don't always agree with his take on these, but nevertheless, I am enjoying the ride.
I am about half way through and I will write more when I've finished it, because I get the impression that the story will take further shape as it goes.
