Riders West (Musaicum Vintage Western). Ernest Haycox

Nan Avery is a woman with troubled past and smeared reputation who decides to move from her hometown in order to escape some unsavory romantic entanglements and run away from gossips and people talking. She goes west to the town of Trail, seemingly a dull and common cattle town on the prairie, but like many of those, it has a secret. Nan learns of a territorial cattle war that goes on in the town and her involvement makes things complicated.
