The Last Outlaw by Rosanne Bittner

Times have changed, and the old Wild West is becoming a place of civilized law and order, where men like Jake Harkner no longer seem to fit in. As a nod to the changing times, Jake has sworn to hang up his guns once and for all. In fact, he and his wife Randy are enjoying this new era of peace on their ranch…until Jake’s embroiled in a rescue mission that he simply can’t refuse―possibly his most dangerous yet. He rides into Mexico to save a young girl from a dreadful fate, leaving his beloved family behind, fearing he will die the same way he’s always lived―by the gun.
