This book is somewhat less comprehensive than Taekwondo The State of the Art, but is an excellent book in its own right, particularly for its display of poomse, not only the Taeguk series, but also 2 Kibon, 8 Palgwe and 9 black belt patterns . The authors use 208 of their pages for Poomse, which are well photographed with foot diagram illustrations. It's the only English language edition I've seen with the Palgwe and black belt patterns shown.
Interestingly, Gaetane Ricke was born in Canada although she received her higher education in the US.
With the heavy concentration on patterns, this book is suitable for all Taekwondoists including black belt students, since it not only shows the black belt patterns very effectively, but also discusses the philosophy that underlies them. In fact, the authors present the 8 Kwae bar symbols that surround the Taeguk and discuss them in a paragraph as part of the presentation of each of the Taeguk poomse. For students who intend to proceed in TKD, this is important information and makes for a richer learning experience. As a person with acting training, I understand the importance of images and sub text to support action.
As with most TKD books, the photographs only show end or beginning positions and the discussion does not go far enough to help the beginning student understand the nature of the transitions. Supplemented with good teaching by a qualified master, such as my own, Master Sang Ho Seung, the book supports TKD very well. And I think that is the intention of the authors.
The large font size used in this book makes for an easily readable text for all ages. The use of Korean terminology is limited. Only the number and names of patterns have the Korean name shown. However, many other sources including your TKD master are available for this.
What pleases me here is the quantum leap in the quality of this book relative to many of the other books on the market about TKD. I've been exposed to a number that are poorly written, if well intentioned, with awful proofing for English spelling and grammar errors.
Any young Taekwondoist nearing black belt would be well advised to add this book to his or her library. I believe that you will refer to it repeatedly, especially to refresh your memory on fine points in the Palgwe and Taeguk patterns.
