When John Carter discovers that his beloved wife, Dejah, has been imprisoned in the Temple of the Sun, he is desperate to rescue her. However, the prison, which slowly rotates, is only opened once a Barsoomian year. As Dejah's prison sentence drags on for over a hundred days, the window of opportunity is narrowing for Carter to save her. Amid social and political unrest from the last war, the Thern had appointed a new leader, but many still believed in their ideologies. When Carter discovers that the new Thern leader, Matai Shang, and another new leader, Thurid, know the secret of the Temple of the Sun and intend to plan a prison break, he follows them, in hopes he could benefit from their plan. After Thurid and Matai Shang break out the prisoners that they planned to rescue, Phaidor, the daughter of the Holy Thern, and Thuvia, a Barsoomian princess, the two decide to take Dejah as well, not to save her but out of spite and contempt for Carter. As Carter chases after them in hopes of freeing his wife, he risks it all to save her and restore peace, encountering ambushes, new discoveries, and dramatic trials. The Warlord of Mars by Edgar Rice Burroughs is a nail-biting adventure that continues the narrative of its predecessor, The Gods of Mars. First published in 1914, Burroughs' imaginative work is a perfect example of 20th century pulp fiction. Descriptive prose and an exciting plot are paired with thought-provoking themes of race and religion, allowing The Warlord of Mars to remain adventurous, fun, and reflective to modern readers.
