The author of the unusually interesting autobiography, "Child of the Revolution," (noted here July 1958) now turns to political analysis in this ambitious study of developments within the U.S.S.R. since Stalin's death. Based on an extensive use of the documentary evidence, it is centrally concerned with the struggle for power and Khrushchev's rise to the top. In general he finds the Party strong and the system modernized rather than liberalized.
