Welcome to New Crobuzon, a city that breathes smoke and bleeds secrets. Beneath its factories and foundries, humans and hybrids, magicians and criminals, all claw for survival under the iron rule of Parliament. It is a place where wonder and horror live side by side.
Into this chaos comes a stranger with a golden purse and an impossible request. One experiment sparks a chain of events that unleashes an alien terror beyond comprehension. As panic grips the streets, unlikely renegades must rise from the shadows to face it.
But New Crobuzon is no ordinary city. Its soul is forged in violence, stitched with magic, and hardened by survival. What hope do a handful of outcasts have against the doom that now stalks its skies?
