That books and it’s sequel 'the wall of storm’s are really good takes on early to mid Han dynasty. The first book follows events of the fall of the Qin and the rise of the Han really closely while the second books mixes it in terms of the time scale. It has me really interested to see how Liu adapts that later Han history in the third book.
