Herma is many things: a glamorous story of a singer who rises from the choir of a country church to stardom at the Paris Opera: the parallel adventures of her agent and friendly enemy Fred Hite, filled with the excitement of the early days of aviation; and a provocative sexual intrigue whose twinned her and heroine, not brother and sister, are forbidden to each other by the secret that lies at the center of their odd and intimate relationship. Starting in Southern California, Herma moves on to larger world, starting with the brash adolescent San Francisco of the period.
