The Mountain Valley War (Kilkenny #2)

Holed up in a cabin in the Idaho hills, the mysterious man who called himself Trent wasn't looking for trouble. It came looking for him. A trigger-happy kid named Cub Hale emptied his gun into an unarmed man. Then he came swaggering after Trent. The girl who ran the gambling hall tried to get him to hightail it. But Trent wasn't buying. Even in that forsaken back country, he knew when a man had to speak with his shooting iron.
