It is apparent to me now that you cannot separate any of the parts of the tetralogy of Aegypt from itself. It should, and must, be experienced as a whole. Endless Things is the end, the final culmination of what is likely the greatest work of fiction by a modern author that I've read. I'm baffled that the entirety of Aegypt is not more widely known. It should be lauded and Crowley held up as one of our greatest living authors. It's a masterpiece.
