Tread of Angels

"Looking for a little mystery with a weird-west genre hook? Look no further! In a world of mechanical wonders powered by the divine magic of a dead angel live sisters Celeste and Mariel, descendents of the Fallen angels. Celeste will do anything to save Mariel from execution after she’s accused of killing one of the righteous Virtues – including making deals with demons, scamming her fellow Fallen, and trying to outsmart the enemy Virtues."
