This book consists of three basic parts: An introduction which includes a biography of Robert Cochrane, a few writings of Cochrane's, and a larger number of writings by Evan John Jones. These come out of the Tubal Cain Witchcraft tradition.
I found the biography and introduction to be quite interesting in its own right. There isn't a lot to be said here except that it covers the basic outlines of Cochrane's life and his controversies, giving a picture of depth to the man and his works.
The writings of Cochrane himself, I found interesting to ponder as philosophy generally. His concepts of truth, magic, fate, the Gods, etc. are quite a bit different than I have come across in the neopagan scene, and indeed Cochrane certainly did not consider himself to be neopagan.
The writings of Evan John Jones generally are more pagan and operant in nature. These cover outlines and discussions of various rituals, symbolism of tools, etc. In general, as a non-Witch, I found these less interesting.
Later in the book, however, Jones turns back to discussing Cochrane's philosophy, life, and death, and in these essays something deep is touched upon.
