Peace in an Age of Metal and Men — Anthony W. Eichenlaub

Something ain't right in the town of Swallow Hill. A boy's cold-blooded murder yanks J.D. from his life of peace. Guilt at past failures drives him, but soon the problem in Swallow Hill proves to be too much to solve alone. Problem is, there's nobody he can trust: not his old war buddy, not the sheriff, and definitely not the good-looking gentleman from the city. Seems everyone around wants him to shoot someone else. J.D. has to decide: is he going to go in guns blazing, or is there a better way? Can there possibly be Peace in an Age of Metal and Men?
