This is a hymn to a Man who himself overcame seemingly insurmountable obstacles. A man who, by his example, as well as his bright artistic words, taught others not to succumb to circumstances, not to panic, but to find the strength to live and achieve a great goal in the name of Freedom, Equality, Happiness, which - and he believed in this - would certainly become the norm of life on Earth! The whole life of Nikolai Ostrovsky - an example of service to his duty, loyalty to his convictions - was a feat and embodied in his novel “How the Steel Was Tempered”, which became a bestseller of the Soviet era.
