B. M. Bower 
Flying U’s Last Stand [PDF ebook] 

Groundbreaking Western writer Bertha Muzzy Bowers was one of the first female authors to gain popularity in this traditionally male-oriented genre. In The Flying U’s Last Stand, Bowers returns to the scene of many of her most popular works, the Flying U Ranch, which is under siege from a wave of invading homesteaders who have laid claim to parcels of the sought-after land.
