Widely regarded as his major work, Crowley's Magick in Theory and Practice is an extensive treatise on magick, a system of Western occult practice synthesized from many sources, including Eastern yoga, hermeticism, medieval grimoires, contemporary magical theories, and Crowley's own original contributions. As important today as when it was first written, Magick in Theory and Practice is essential listening for anyone interested in occultism.

The Book of the Law, the holy text that forms the basis of Thelema, was transmitted to Crowley by the entity known as Aiwass in Cairo, on three successive days during April 1904. Acting as a medium, Crowley recorded the communications on hotel notepads and later organized his automatic writing into a short, coherent document. Aiwass/Crowley presents The Book of the Law as an expression of three god-forms in three chapters: Nuit, Hadit, and Ra-Hoor-Khuit.

A year or so before the beginning of World War I, a young woman named Lisa la Giuffria is seduced by a white magician, Cyril Grey, and persuaded into helping him in a magical battle with a black magician and his black lodge. Grey is attempting to raise the level of his force by impregnating the girl with the soul of an ethereal being — the moonchild. To achieve this, she will have to be kept in a secluded environment, and many preparatory magical rituals will be carried out. The black magician Douglas is bent on destroying Grey’s plan.

When Sir Peter Pendragon, a retired pilot of the Great War, meets the free-spirited Louise, a devotee of the mysterious occultist Basil King Lamus, the two immediately get married and set off across Europe, on a drug-fueled honeymoon of heroin and cocaine. Eventually, in an attempt to break free of their recently acquired habit, the newlyweds find their way to the Abbey of Thelema in Italy, where the adults perform invocations to the sun and the children freely recite passages from the Book of the Law.

Edward Alexander Crowley was born on 12th October 1875 to wealthy parents in Royal Leamington Spa in Warwickshire. He was educated at Malvern College, Tonbridge School, Eastbourne College and finally Trinity College, Cambridge where he focused on his passions of mountaineering and poetry and published several volumes. His literary works were both prolific and covered many topics. In the early part of his career he published many poetry books, even plays, before his darker and more forceful works came to dominate his output.
