Thank IAD BALT it is out of print!
Truly a terrible book. The information is either pulled straight out of other books, and full of errors, or Schueler is on some flight of fancy that has nothing to do with Enochian. After reading this book, it is apparent that he does not practice Enochian Magick at all. Even for Llewellyn, which is famous for releasing poorly researched books, this is a low. Pass up any of Schueler's books, and get one by James or Tyson instead. Or go straight to the diaries ;)The Angels themselves will give you all of the Advanced Enochian you can handle!
