The Gulag--a vast array of Soviet concentration camps that held millions of political and criminal prisoners--was a system of repression and punishment that terrorized the entire society, embodying the worst tendencies of Soviet communism. Applebaum intimately re-creates what life was like in the camps and links them to the larger history of the Soviet Union. Immediately recognized as a landmark and long-overdue work of scholarship, Gulag is an essential book for anyone who wishes to understand the history of the twentieth century.
