The introductory chapters in which Huang explains the development of Tai Chi and relevant physiological concepts are the best I have yet read and I would recommend them to any English speaker starting to learn Tai Chi. As with most attempts to describe how to do the form I found the detailed explanation of how to do Huang's short version of the Wu style form of little practical value; although to be fair I only read parts of it out of general curiosity as I practice Wu style in Hong Kong with the Wu family. Although the introductory paragraphs brought out the fact that Tai Chi is primarily a martial art I felt that once the book began to discuss the form this was forgotten. I have found that the greatest insights into the form often arise when one learns their martial application.
