Query: Chung Do Kwan revisited

This is a good work of one of the most respected "styles" of Taekwondo out there. It is a great companion to both Korean Karate and Black Belt Korean Karate both by the 2nd Head of the Chung Do Kwan GM Son, DukSung. I would recommend this book to anybody that studies "traditional" "Korean Karate" I think the authors did a good job in describing the art of Chung Do Kwan well.
