What I found most interesting about this book, and perhaps the most difficult, was the assumption on the part of the author that the reader is capable of extremely advanced magical workings. The majority of the boook, and not suprisingly so given the Sun Tzu roots, focuses on what can best be described as battle magick. There is much mention of the use of offensive magick (hexes, curses, energy attacks) and defensive magick (sheilding, binding, protective enchantments). While I am pleased to have found such a directly informative, and completely unapologetic, book about the philosophy and application of such magick, I will say that the book is not a good tool for beginners. The novice will find it confusing and seemingly only a small departure from the source text, while in truth it is quite a step beyond just the world of physical weapons.
