The first published book by the creator of Tarzan of the Apes that introduced the world to intergalactic Civil War soldier, John Carter  Two years before Edgar Rice Burroughs became a worldwide celebrity with the publication of Tarzan of the Apes and its twenty-two sequels, which together have sold more than 30 million copies, he published the futuristic sci-fi romance, A Princess of Mars. A Princess of Mars tells the story of John Carter, a Civil War veteran who inexplicably finds himself held prisoner on the planet Mars by the Green Men of Thark. With Dejah Thoris, the princess of another clan on Mars, John Carter must fight for their freedom and save the entire planet from destruction as the life-sustaining Atmosphere Factory slowly grinds to a halt. A Princess of Mars is the first in Burroughs' eleven book Barsoon series, following the continued adventures of John Carter.
