Aleister Crowley's Moonchild is a heady, entertaining romp of a tale with philosophical underpinnings. The allegorical plot about a war between two rival magicians dramatizes and illustrates the practice of Thelema. The reader sees Thelema in action and learns of Crowley's broader beliefs and philosophy as the story unfolds. "Do what thou wilt shall be the whole of the law; Love is the law, love under will." A phrase of great import. In Moonchild, Crowley demonstrates the fate of those who would misinterpret its meaning and be seduced by the temptations of Black Magick.
