The Half Made World by Felix Gilman

In a grim, half-formed frontier world caught between two opposing forces—the relentless, industrial-expanding Line and the roaming, almost-sentient violence of the Gun—a ragged pair of outsiders are swept into a collision that will decide how the continent is finished. Traveling through towns and wastelands populated by factory-made automatons, itinerant gun-crews, and people trying to survive between progress and anarchy, they uncover lost histories, uneasy alliances, and the human costs of both order and freedom. Blending Western grit, steampunk machinery, and dark fantasy, the story examines power, agency, and the moral compromises inherent in shaping a world that is still being made.
