Beyond the Crimson Skies — Owen G. Irons

Kendo was looking for salvation as well as retribution. Of these two retribution was the simpler to exact. Losing Frank Pierce's horse herd to raiding gunmen had not been his fault, but it was bound to ruin Kendo's reputation which had already been severely darkened by past failure. Left alone and afoot on the open plains by treacherous companions, he needed to track down the outlaws and recapture the horses, the sale of which Pierce was banking on to save his small ranch. That alone was a vast challenge and Kendo couldn't know how much worse it could get before he encountered the beautiful woman who was intent on building an outlaw empire in the far country.
