I enjoyed listening to the book while exercising. I liked its explanation of chi and cultivating. The main character has drive and discipline. What I would like to see is a character with more spiritual depth and heroic qualities. The cultivating seems to have everything to do with physicality and nothing to do with enlightenment. Maybe that is addressed in further books. I don’t really admire the main character for his morality or admirable qualities. He’s kind of just like a jock who wants to better his life. The writing does well at explaining the fighting scenes. The book is a series of fighting scenes and cultivating to get healed. A little more depth would have been nice.
