This is the fifth audiobook in the "Mars Series". There is a game on Mars similar to chess - very similar, save that it is played on a board of a hundred squares, and with ornate pieces. The Martians call it jetan, and it is as old as the civilization of Barsoom. But in the Martian city of Manator, jetan is no game.

Impetuous and headstrong, Tara, Princess of Helium and daughter of John Carter, defies the elements by flying into a rare, fierce Martian storm. Hurtled half a planet from her home, she is threatened by grotesque, flesh eating monsters and barbarous warriors. Is the mysterious Panthan warrior friend or foe? As hero battles for maiden in the chess-like games of Jetan, the pieces are fighting men and the stakes are life and death!

Tara of Helium, daughter of John Carter, becomes lost in an unknown area of Mars when her single-seat flier is caught in a rare Martian hurricane. She is first captured by the bizarre and hideous Kaldanes, and then the brutal Manatorians, for whom she is the prize in a tournament of Martian chess, jetan, that is played by live game pieces, and to the death! 

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.
