I finished the book anyway and I'd definitely recommend it, as well as being written by a sometime Dissensian it deals with lots of topics that regularly come up here, the following and more all get a mention, mostly in passing but in some cases in more detail; Surrealism, Lettrists, Wilhelm Reich, Theosophists, Masonry, Satanism, MK Ultra, Kant, Jacques Dutronc, Rick Owens, Vice Magazine etc etc
If you know Lewis you'll recognize some characters and events from his life but they are hardly important to the story which is very readable for the most part. Towards the end it goes... well some might find it too silly but it didn't spoil it for me. I guess endings are just difficult.
