The Gulag Archipelago by Aleksandr Solzhenitsyn.
Along those lines, anything by Ayn Rand. She came from Russia and knew the evils of Communism first hand. She also predicted America's slippery slope into the situation we are in today ("Atlas Shrugged" and "Fountainhead").
Also, Adam Smith's "Wealth Of Nations". It can be a dry read but once you get through it, you totally understand why Capitalism is the best economic system every devised - so far.
A Day In The Life of Ivan Denisovich, also by Soltzhenitsyn.
