A serious job -- a proletarian novel of the life of an Austrian Jew in New York. Young Isaac is brought by his parents from a village in Eastern Europe at an early age, his father fails successively as tailor, janitor, candy store owner, and Isaac and his brother suffer from timidity and poverty, until Isaac finds his own niche. Long, detailed picture of Isaac's growth, the lives of the family and friends, the background of slums, abortive business ventures, racial antagonisms. Sordid in many spots, and at times heavy going. Lacks the intensity and gusto of the Gollomb book, Unquiet. For a Jewish market, primarily.
