MP3 CD Format Ulysses Paxton, mortally wounded on the battlefields of WWI France, is transported to the planet of his dreams, Barsoom (Mars). There he becomes the assistant of the Master Mind of Mars, Ras Thavas, a medical genius. Burroughs anticipated such modern marvels as organ and limb transplants, exploding bullets, anti-grav fliers, and some we haven't yet invented! When Ras Thavas switches the brains of an evil and wizened Jeddara (queen) into the body of a gorgeous young woman, our hero vows to right the wrong. Swords and sci-fi action abound in this sixth of ERB's Mars series. Edgar Rice Burroughs (1875-1950), born in Chicago, was educated at Michigan Military Academy and served briefly in the US Cavalry. He began writing while working as a pencil-sharpener salesman, publishing his first piece in 1912 to great success. He authored numerous science fiction and fantasy series but is most famous for his Tarzan books; the suburb of Los Angeles where he lived eventually became known as Tarzana.
