Much of this book is from the diary record of the author-an adventurous magician that flits owl-like through the twilight realms of sorcery only to reappear as the soaring falcon of spiritual light. Each of the twenty-two chapters is divided into two sections, Light-path and Night-path, and is headed by a commentary on the relevant text from the Sepher Yetzirah. The methods include Theurgic, Goetic and Enochian magick. The narrative is anchored through earth location, in this case the 'Island' promontory on the West Penwith Peninsula. The book thus has a distinctly elemental nature, reflective of changing weather and seasons. Various themes are woven together, one of which reveals what it was like to work as an Initiate of Kenneth Grant's Typhonian Order. The culmination is a magical battle between sorcerers. The experiential account is nonetheless accurate to the last detail; the events in the so-called real world mirror the interior worlds of spiritual and magical working.
