"Several recently-published biographies of Crowley do justice, for the most part, to his life and works. But, with all due respect to the authors, their offerings now stand like skeletal frames of unfinished houses next to Kaczynski's magnificently constructed edifice. Every brick is set in place with the mortar of meticulous research and insight. Thank you Dr. Kaczynski. I've waited thirty-five years for this."

--Lon Milo DuQuette, author of The Enochian World of Aleister Crowley.

"Dr. Kaczynski brings two unique qualifications to this massive biography of the Prophet and Master of Magick, Aleister Crowley. One is his formal command of the rules of academic discipline. Dr. Kaczynski is a university professor who moves comfortably in the realms of research institutions and the masses of data contained therein, and who has internalized the rigors of classical intellectual pursuit. Dr. Kaczynski is also a practicing adept of the Thelemic magical system as taught by Aleister Crowley. Thus he is able to analyze and interpret many of Crowley's insights and spiritual states from his own personal experience. This is a magnificent book and is highly recommended."

--James Wasserman, author of The Militia of Heaven and Art and Symbols of the Occult.

"At long last, the world has a balanced and readable biography that reflects how magick shaped every facet of Aleister Crowley's life. And Dr. Kaczynski doesn't dismiss magick as humbug or mumbo-jumbo, but validates it as a legitimate method of spiritual development meriting serious study. He is on the bleeding edge of academic research on occultism."

--Christopher S. Hyatt, Ph.D., author of Undoing Yourself.
