More of a 3.5/5 for me; I enjoyed the illustrations and artwork, and believe they alone are worth getting this book for. There's just something about the artwork that arises from Crooked Path Sorcery that draws me in and I've revisited this work from time to time just to admire the artwork.
Certain specifics about the practice (timing/date-wise) feel slightly opaque and could use a little bit of fleshing out - or maybe the specifics are just on the denser side and I need to write them down and transpose them into a calendar to see how the journey would function from a logistics standpoint.
Either way, I've been a fan of Atramentous Press' offerings ever since acquiring the codex althaeban malik and this is certainly one that a fan of that publisher should get to round out their library. The author's journey presented here, based on workings over a few years, has been inspirational and something I'd like to adapt to my own practice.
If the author ever did a follow-up to this work (the text of which left me wanting more as it had captivated me) and dived into more detail through expositions, would be an instant buy for me.
