This book takes a lot of the concepts of Gilles de Laval's previous books and brings them all together. It introduces a lot of concepts surrounding the idea that all magick is black magick, and taking a Satanic lens, bringing it all into a lot of unique perspective on the Qliphoth. While this book is far from something to start with, it adds a lot of unique perspective not just to Gilles' works, but other Qliphoth-centric magick text. To those who dive into these type of books, or those who have dived into Laval's other selections, this is a great addition to those texts.
