Robert Anton Wilson at one point was going to publish a book called Lion of Light, about Aleister Crowley. I don't know how much of it got written, or what happened to it, but Jesse Walker has spotted an article from Green Egg magazine, "Crowley, Leary and Genetics," which is an excerpt from the planned book. The digital issue of Green Egg (Volume VI, No. 60) can be checked out for an hour apiece from the Internet Archive. "Plus a bonus bit of Discordianism on page 10, and a RAW letter on page 34," Jesse notes.
