When Hitler invaded Poland in 1939, Mary Berg was fifteen years old. From that time, until her arrival in the United States in 1944 by exchange through her mother's American citizenship, she kept a day-to-day record of her four years in the Warsaw Ghetto, confinement in a Warsaw prison, dispatch to the internment camp in Vittel, France, and finally, her journey to freedom. For the first time since 1945, this - the first and lengthiest eye-witness account of Jews' experiences in the Warsaw Ghetto - is available to the English-speaking public. This is a work remarkable for its authenticity, detail, and poignancy. But it is not only as a factual report on the life and death of a people that Warsaw Ghetto ranks with the most remarkable documents of Second World War. This is the personal story of a life-loving girl's encounter with unparalleled human suffering, a uniquely illuminating glance at one of the darkest chapters of history.
