The Chessmen of Mars

Human chessmen who must fight to the death at their masters' command-such is but one of the many thrills that await the reader in this terrific tale of adventure and discovery in the lost cities of Barsoom-the Mars of Edgar Rice Burroughs!

Gahan of Gathol pits his sword against heads without bodies and bodies without heads, against a fiendish monarch, and against the terrors of a forbidden city-with his reward the hand of a captive maiden, Tara, the Warlord's daughter.
