This is a fun little fantasy / mystery read.

War between angels and demons in the old west left the precious material Divinity waiting to be mined. Celeste and her sister, half fallen, are making their lives here when her sister is accused of murder. It's up to Celeste to prove her sister's innocence.
It's an interesting novella. I wasn't as engaged with it as I was Black Sun, but I'll likely pick up the sequel to see where the world building goes.
