A story of the life of an American Catholic Priest who ends up in the USSR during and after WW2 and his life and times there as a prisoner till he leaves to come back to the USA after 23 years. Fascinating and remarkably similar to Solzhenitshen's Gulag Archipalego. This is not great literature but adds another perspective to the USSR in Stalin's time period and after it, up until about 1964.
I do wish he had included his adjustment back into American life.
