A Princess of Mars
Burroughs began writing the Barsoom books in the second half of 1911 and produced one volume a year between 1911 and 1914; seven more were produced between 1921 and 1941. The first Barsoom tale was serialized in "The All-Story" magazine as "Under the Moons of Mars" (1912), and then published in hardcover as the complete novel "A Princess of Mars" (1917). The final Barsoom tale was a novella, "Skeleton Men of Jupiter", published in "Amazing Stories" in February 1943. The novel editions of "A Princess of Mars", "The Gods of Mars" and "Llana of Gathol" contain newly written forewords describing Edgar Rice Burroughs' interactions with John Carter, who is described as Burroughs' great-uncle.
