I should have investigated better before picking up this book. I thought it was some kind of a sociological study of different groups centering around the end of the world (as we know it), from midwestern preppers to billionaires building expensive retreats in New Zealand's mountains. It was about that, but only marginally. It was first and foremost a personal memoir, with lots of musings about the author's fears and anxieties, his travels, books he had read (lots of quotes and name droppings), and his political views.

I'll be honest. If it had been any longer than 200 pages, I would have dropped it. I am not interested in memoirs, and there was not much other information in here. Actually, in the second half, there was none.
