Howard Fast's life, from a rough-and-tumble Jewish New York street kid to the rich and famous author of close to 100 books, rivals the Horatio Alger myth. Author of bestsellers such as Citizen Tom Paine, Freedom Road, My Glorious Brothers, and Spartacus, Fast joined the American Communist Party in 1943 and remained a loyal member until 1957, despite being imprisoned for contempt of Congress. Gerald Sorin illuminates the connections among Fast's Jewishness, his writings, and his left-wing politics and explains Fast's attraction to the Party and the reasons he stayed in it as long as he did.
