Vengeance Is a Bullet

Carl O'Bannion was a mere boy when his parents were mercilessly gunned down by a gang of former Union guerillas led by Major Jamison "Wolf" Avrial. Now, after ten years of perfecting his skills as a gunslinger, O'Bannion is known as Carlos the Snake. He's been hunting down Avrial's men and leaving a trail of bodies across the frontier, and Ranger Sam Burrack is hot on his trail.
