> The Gulag Archipelago

I did read it a few years ago, that's very though and it describes in a very technical way how gulags worked. In hindsight I'm not sure it was the best way to do it.

If you liked it tho, id suggest the two kravchenko books on the trials, Rudolph Hess book (very interesting), Simon Sebag Montefiore book on Stalin.

I can provide many more about this kind of subject, I found that fascinating for a few months and did read a lot of books on it.

Although I'd argue that the most fascinating is watching the usa, from outside, turn into a totalitarian state. That is truly incredible to be able to witness how much Trump achieved in a few months.
