Where once there were twelve great cities, now only four remain, and their borders are being threatened by the growing cloud of darkness. The last humans are fighting back with ever more bizarre new machines. But one by one the defences are failing. And the Roil continues to grow.
With the land in turmoil, it’s up to a decadent wastrel, a four thousand year-old man, and a young woman intent on revenge to try to save their city… and the world.
