New York at the end of the 20th century--hardly St. Augustine's city of God--is the canvas on which Doctorow paints an impressionistic portrait of man's frail moral nature and the possibilities of redemption. Challenging and provocative, this rambling narrative is a mix of alternating voices that touch on such matters as theology, popular music, astronomy, physics and science, war, carnal love, the verisimilitude of film to life (and distortions thereof).
