Communist North Korea suffered a devastating famine in the 1990s after the collapse of the Soviet Union which had been one of the country's main supporters. Hundreds of thousands of people died of starvation. Some estimates put the death toll at more than two million. Josephine Casserly has been hearing from Joseph Kim, who was a child in North Korea in the 1990s, about the struggles of his family.

Joseph has written a book about his experience called Under the Same Sky.
