The aquariums of Pyongyang : ten years in a North Korean gulag
(Book)

After the division of North and South Korea, Kang's family returned to North Korea from Japan, where his grandparents had emigrated in the 1930s. His grandfather had amassed a fortune and his grandmother became a committed Communist. They were fired with idealism and committed to building a new Korea, only to be removed without trial to a remote concentration camp, apparently because the grandfather was suspected of counter-revolutionary tendencies. Kang Chol-hwan was nine years old when imprisoned at the Yodok camp in 1977. Over the next ten years, he endured inhumane conditions and deprivations, including an inadequate diet (supplemented by frogs and rats), regular beatings, humiliations and hard labor.
