Upton Beall Sinclair, Jr. (1878 - 1968) was an American author who wrote nearly 100 books and  won the Pulitzer Prize for Fiction in 1943. Sylvia (1913) is a novel about a Southern girl. In her autobiography, Mary Craig Sinclair -Upton's wife- said she had written the book based on her own experiences as a girl, and Upton collaborated with her. She asked him to publish it under his name. When it appeared in 1913, the New York Times called it "the best novel Mr. Sinclair has yet written-so much the best that it stands in a class by itself."Sylvia's Marriage (1914), was the sequel, also written by Craig and Sinclair, but published only under Upton Sinclair's name.We present you in this volume the complete saga of this amazing work.
