The Vigilante Chronicles Series by Natalie Grey, Michael Anderle

One man leaves the life of a lawman behind him and works to clean up a new area in space. On the planet now known as High Tortuga, the mine workers are far too close to being slaves so the ruler of the planet shut them down. Except for the mine owned by Venfirdri Lan. He's taken his mine off the grid and decided to keep everything running. With no need to pay the workers, profits should be good... moreOne man leaves the life of a lawman behind him and works to clean up a new area in space. On the planet now known as High Tortuga, the mine workers are far too close to being slaves so the ruler of the planet shut them down. Except for the mine owned by Venfirdri Lan. He's taken his mine off the grid and decided to keep everything running. With no need to pay the workers, profits should be good. After all, who's going to stop him? He had no idea there was a new type of man working for justice on the planet. A man named Barnabas. In fact, he didn't even know who Barnabas was. But he's about to. Barnabas may not be Ranger One anymore, but one thing definitely has not changed: when someone screws over the powerless, Barnabas is going to bring the pain. With a bloodthirsty AI running his advanced spaceship, those who love evil should start looking over their shoulders. Life just got a lot more fun. --- NOTE: This book contains cursing.
