I have spent many an enjoyable evening reading this and really enjoyed it but I would say two things. One observation the second a critisism. 1) Observation. Is not written like a history book where the references to sources are clearly marked but, no great loss. 2) What I felt it did lack were maps, diagrams and pictures to make it easier to follow the 'plot'. Yes there are maps and pictures but they are few and no where near detailed enough to trace events. The pictures are interesting but ofmuch less relevance. Still excellent book and I will look up more of his works!
