This is a veeery dark book. In his usual style EAK teaches how to do it, the darkest deed that is, with many practical details and personal anecdotes. The amount of rituals is just mindboggling, it never ends! Death magick from all paths: Goetic demons, Gatekeepers of hell, candle magick, Hoodoo, Necronomicon spirits (eeeh Gad!), sigil magick (and those sigils, my GOD!).
This is the kind of book that mystic of all ages has been searching for, travelling to far countries, paying fortunes for.
