The Rise and Fall of D.O.D.O.

Didn't enjoy this as much as some earlier Neal Stephenson books. Not sure why, but I just couldn't relate to the characters. However, there is plenty of action and there are some good time-travel twists.
Also, the growth of D.O.D.O. as the story progresses provides and excellent example of Pournelle's Iron Law of Bureaucracy in action.
The audio version is very well done.
3+ stars, but I cannot quite bump it up to four.
