Night of Fire and Snow — Alfred Coppel

Night of Fire and Snow, first published in 1957, is a novel examining the life of a rising young writer who develops and eventually overcomes his writer's block. Interspersed are recollections of youthful love affairs, a marriage to a decent and also rich woman during the war, a long lasting affair with his best friend's wife (a top Hollywood starlet), and a liaison with his sister-in-law.
