Amazon has it, but I'm trying to stay clear as best I can. At least privately owned book stores should have it listed on Ebay or even Etsy. The author did a podcast with Joe Rogan awhile back for a "grade school" understanding of it. It's good to start because the information is easy to digest. He just did a podcast with Bret Weinstein that is more of the "gifted and talented" level.

FWIW, look up Jonathan Pageau on youtube. He's got an amazing channel that goes into many of the topics people are bringing up.

I look at ancient knowledge as the particle physics of modern conspiracies. If you can understand the operating system, everything else falls into place.
