Giant Spiders. Death Ray Guns. Personal Flyers. Cannibals. Sword Fights. From the fertile mind of Edgar Rice Burroughs comes the tale of A Fighting Man of Mars. Hadron of Hastor sets out to rescue a lovely kidnapped woman he believes he is in love with. Along the way, his adventures among the little-known ancient cities of Mars, his comradeship with a brave warrior-woman named Tavia, and their struggle together against the hordes of a cunning monarch, make for an exciting classic science fiction adventure.

Under the double moons of Barsoom, an invisible flier sped to the mysterious city of Jahar where Sanoma Tora, the kidnapped princess of Helium, had been taken. Hadron of Hastor was at the controls, hatching a rescue plan that required unusual daring and great ingenuity. For invisibility alone was not a great enough weapon against "The Death." And should Hadron succeed, what fate would await him at the hands of the madman whose very genius had created the means of that rescue?
