In addition to his Hughes' memoir, Sederberg wrote over a dozen novels, including "The Kingmakers" (1984), about a fictional Los Angeles newspaper family, and "Zora" (1989), a revenge story concerning the Armenian genocide. His best known novel is "The Power Players" (1979), about which the "Los Angeles Times" observed, "Sederberg has much to reveal about the clandestine workings of multinational conglomerates, and the men who run them." "The Washington Post" was also appreciative of the novel, saying that "Sederberg understands people and how to write about them," and "The New York Times" called the book "more fun and certainly more plausible than [Sidney] Sheldon's recent and impenetrable 'Bloodline.'" Sederberg also wrote a handbook for stock investment clubs and a history of the bombing of the "Los Angeles Times" by pro-labor anarchists in 1910.
