Subbota - My Twenty Years in Soviet Prison (Avraham Netzach)

Avraham Netzach survived twenty years of captivity in the prisons and slave-labor camps of the Soviet Union.
Throughout two decades of tremendous human suffering, he remained faithful to his religious principles.
In every prison in Russia, he was known as Subbota (Sabbath), for despite of all efforts by his oppressors to break him, he never worked on Shabbat.

The cry of thousands who went through the same terrible experience, but did not have the good fortune to come out alive, is echoed in Avraham Netzach's work.
