Adventures of a Young Man [EPUB ebook] 
A Novel

In a novel that closely parallels author John Dos Passos’s own ideological struggles during the Spanish Civil War, protagonist Glenn Spotswood, an American, travels to Spain to fight on the Republican side. There, Spotswood joins the Communist Party to help establish a more just society, but his idealism quickly degrades under the stress of party orthodoxy and hypocrisy.
