Query: No Pulitzer for this one

If you liked "Guns, Germs and Steel" then you will probably like this book too. It is a lot easier to put down, but I had to finish it like a dose of medicine that tasted bad so it must be good for me. Actually, that sounds a little harsh and I really do recommend it. It seems less inspired that "Guns" and a like a bit of exploitation of that former great success. Maybe I am a little depressed because this is the third book I have read recently that presents a rather bleak view of the future. It is definitely a worthwhile read.
