The Chessmen of Mars

Tara of Helium has inherited her father's stubbornness along with his courage, and when a rogue storm sweeps her flier into the unmapped wastes of Barsoom, she finds herself alone in a world stranger and more dangerous than anything the red planet has thrown at her family before. What follows is a chase across a dying world — through the territories of creatures that defy easy categorization, into a city where a deadly game of living chess determines who lives and who dies. The stakes are personal and planetary at once, and Burroughs keeps the tension coiled tight from the first chapter.

This is Burroughs at his most inventive in the Barsoom series, trading some of the earlier books' swashbuckling momentum for genuine strangeness. The Kaldanes — parasitic intellects riding headless human bodies — are among the most unsettling creations in pulp science fiction, and the novel earns its central chess metaphor rather than simply gesturing at it. The prose moves with Burroughs' characteristic velocity, but the worldbuilding here has an odd, dreamlike logic that lingers. Readers who've followed the series will find this fifth entry the most conceptually daring of the bunch.
