Well as Im sure you can imagine these books of hers are quite in depth. Very slow resding, but thats fine. The sources alone could make up a book themselves.

I've heard her talk about these books in interviews and she digs deep and seems to know her stuff!
One of the best journalists ls ever imo. And I can put noone above her of living ones. The first book goes back to early 20th century, pretty much setting up how things lead to the more familar things that volume 2 covers. But yea after like the 20th podcast or whatnot I heard her talking about em I had to get em.
