I published through Amazon. I’m not sure if this book could be done the way it appears. It had to be in the works awhile before it showed up published on Amazon even if AI was used to write. There is the setting up of the account, downloading of the manuscript and the cover, proofing the book after they format it. Signing off on the final approved book. That takes time, maybe not for AI but through Amazon to get back to you on each step. The FBI should go down that hole to see not only who wrote the book but who at Amazon helped to facilitate it being published. Amazon hires a lot of young people to help with publishing so it’s possible that a radical/s could have assisted within the company. They like to foretell their intentions ahead of time. Maybe this was exactly that.
