In 1936 she returned once again to the United States. Quietly and privately upset with news in the USSR (The "Great Purges"), she continued to write for leading periodicals, including "The Atlantic Monthly", "Harper's", "The Nation" and "Asia". A visit to Spain resulted in "Spain in Arms" (1937); visits to China led to "One Fifth of Mankind" (1938). In 1940 she published "My Native Land". Other books include "The Soviets Expected It" (1941); the novel "Wild River" (1943), set in Russia; "Peoples of the U.S.S.R." (1944), "I Saw the New Poland" (1946) (based on her reporting from Poland as she accompanied the occupying Red Army); and three books on the success of the early Communist Party of China in the Chinese Civil War.
