Gustaw Herling’s A World Apart is one of the most important books about Soviet camps and communist ideology in the Stalinist period. First published in English in 1951 and translated into many languages, it was relatively unknown till Solzhenitsyn’s The Gulag Archipelago in the 1970s. However, the narrative of the author’s experience in the Jertsevo gulag was highly appreciated by Bertrand Russell, Albert Camus, Jorge Semprun and others. In this first monograph on Herling’s fascinating life, Bolecki discusses hitherto unknown documents from the writer’s archive in Naples. His insight into the subject and poetics of Herling’s book and the account of its remarkable reception offer readers an intriguing profile of one of the most compelling witnesses of the 20th century.
