A Princess of Mars by Edgar Rice Burroughs
Princess of Mars (1912) is a science fantasy novel, the first in Burroughs’ Barsoom series. It was published in All-Story Magazine from February – July, 1912, and as a novel in 1917.
Full of swordplay and daring feats, A Princess of Mars is considered a classic example of 20th century pulp fiction. The story is set on Mars, imagined as a dying planet with a harsh desert environment. It tells the story of John Carter, a Confederate veteran of the American Civil War, who goes prospecting in Arizona immediately after the war’s end. Having struck a rich vein of gold, he runs afoul of the Apaches. While attempting to evade pursuit by hiding in a sacred cave, he is mysteriously transported to Mars, called Barsoom by its inhabitants.
