It's written by someone on the left, and is a narrative version of what I think is her doctoral thesis. I'm like halfway through this thing and it is absolutely something else. Alphabet organizations operations I've never heard of, cover ups of intentionally exposing 100s of thousands to Sarin, weird connections that would not have happened organically, this book has all of it. Anything strange that happened from 1988 to about 1995 in America is discussed at length. Jolly West even makes a few appearances. At one point she calls Mcveigh the "Forest Gump" of Right Wing terror, and I'm starting to feel like she's right.
If nothing else, it's an incredibly entertaining read. Check out this thread if you want to get a summary of it: https://x.com/BTH_Bill/status/1369843240057397251 .
