One Day in the Life of Ivan Denisovich by Alexander Solzhenitsyn

From the back of the book:
From the icy blast of reveille through the sweet release of sleep, Ivan Denisovich endures. A common carpenter, he is one of millions viciously imprisoned for countless years on baseless charges, sentenced to the waking nightmares of the Soviet work camps in Siberia. Even in the face of degrading hatred, where life is reduced to a bowl of gruel and a rare cigarette, hope and dignity prevail. This powerful novel of fact is a scathing indictment of Communist tyranny, and an eloquent affirmation of the human spirit.
