Return of the Mountain Man by William W Johnstone

Kirby Jensen, aka Smoke, aka Buck West is on a mission. Some dirty, low-down, low-life, murdering snakes, aka Potters, Richards and Stratton murdered his father, his wife and young son, and friend and mentor, Preacher. Now he was on the trail and ready to trade an eye for an eye. Johnstone writes a believable, action-packed novel of life in the untamed west, where law was what you could get and the sheriff was sometimes the face on a wanted poster in another town. I liked it a lot. Sandy Penton
