Passing of an Illusion. The Idea of Communism in the Twentieth Century, Paperback/Francois Furet

A study of Communism and a history of the myth of Communism as perpetuated by its admirers. This book illuminates how the support for Communism and its embodiment, the Soviet Union, became virtually synonymous with "anti-Fascism" and how this strategic arrangement reverberated through the West.
