The Gods of Mars Audiobook (Free)

This is actually the extraordinary story of John Carter, who returns to the Red Planet in search of his beloved, Dejah Thoris. John lands in the Valley Dor, which is filled by vicious place men, and discovers the Lost Ocean of Korus, guarded by the fantastic white apes and horrifying lions of Barsoom. It really is here that he finds the princess Thuvia, who’s a captive of the Holy Therns, high priests who eat only human flesh slain by their place men.

But that is only the beginning of John Carter’s escapades under the double moons of Mars before he battles his way back to his own people as the Prince of the House of Tardos Mors.
