The Gulag Archipelago by Aleksandr Solzhenitsyn
That’s hard core man hats off to you
Its a tough read. Not because of the writing, or the length, but because of where the stories Solzhenitsyn tells take your mind.
Should be required reading, especially for people who vote democrat.
Got thru most of it many many years ago.
And, I agree about the required reading............................but that's probably not allowed in schools any more.
