One Day in the Life of Ivan Denisovich (Everyman's Library) by Alexander Solzhenitsyn, H. T. Willetts, John Bayley

One of the most chilling novels about the oppression of totalitarian regimes and the first to open Western eyes to the terrors of Stalin's prison camps; if Solzhenitsyn later became Russia's conscience in exile, this is the book with which he first challenged the brutal might of the Soviet Union.
