Technology is power, especially in the world where both are sparse. Would those possessing the knowledge be persuaded to share?

Drawn by a vague rumor of an industrialized state out west, Golden Dragon Shang, a visionary hierarch obsessed with all things tech, departs on an irrational journey beyond the edge of the known map, dragging three reluctant sidekicks along.

A fierce raider disowned for insubordination needs all her fighting skills to survive, but even they can't carve the path to her true self. A young smuggler is forced by betrayal to turn his criminal mind to the legit side, for the people who despise him. A soldier struggling with his homeland's troubling past must quash his personal demons to forge alliances with those he loathes, or none on the expedition have a chance.

Unsure of their destination and facing dangers known and unknown, they travel through desolated wilderness half a continent away from home. Their armored train is formidable yet not invincible, and not every enemy is foreign. Survival demands smarts, grudging collaboration, and sacrifice—but will that prove enough?
