The Gods of Mars (John Carter of Mars, Book Two)

After his death-defying feats in Princess of Mars, John Carter was forced to return to Earth—but 10 years later, he's finally sent back to the Red Planet. Carter dreams of reuniting with his beautiful wife Dejah Thoris, but first he must join his Martian ally Tars Tarkas to battle a wide array of enemies—including the deadly Pirates of Barsoom on their speeding aerial craft. Amidst all the thrilling swordplay and intrigue, Carter learns more about the ancient theological, racial, and political divisions that have kept Mars in strife for centuries.
