15 - Warlord of Mars (version 2) by Edgar Rice Burroughs

In the thrilling third chapter of John Carters epic adventures on Mars, our hero faces a death sentence after returning from the land of the dead. Determined to rescue the stunning Dejah Thoris, Princess of Helium, he embarks on a perilous journey across the planet, enduring imprisonment, torture, and fierce battles. Along the way, he cleverly outsmarts his foes, embraces the chaos of war, and navigates complex relationships with women who adore him, all while remaining devoted to his wife. As he dismantles a false religion that has gripped a planet, he offers instead the hope of unity and a promise for enduring peace. (Summary by Thomas Copeland)
