A Six Gun and the Queen of Light

Sirus Logan rides into the town of Bedlam and discovers it's like no town he's been to before!
Logan is hired by the wife of a wealthy ranch owner to take her far away, only to find out she's not whom she appears to be, and becomes familiar with other citizens of Bedlam: hordes, a demon, and harpies.
Will Logan's mission for the Queen of Light deliver her salvation, or will the west never be quite the same again?
