The Vigilante Chronicles

When a mine owner thinks that he's above the law and continues to utilize slave labor to keep his mines running, Barnabas, a former Ranger One, must fight for justice. 

Someone sent three fully armed ships to High Tortuga to back the slave-owners running the mines, and Barnabas and Shinigami are determined to find out who. 

Barnabas has made some enemies - enemies who want to track him down through space and kill him. But he's more than ready to take on this challenge.

Decades of groundwork. Countless civilians abducted, experimented on, and killed. The perfect plan has taken shape, and soon, the entire sector will be under the control of the shadowy Committee. That was the plan anyway. But some human has decided to blow the whole thing up. What do you do when one of those pathetic little newcomers tries to ruin your plans? Make him pay. On the other hand, maybe you should have found out more about this “Barnabas” guy before trying that. But it can’t possibly go too far wrong, can it? Soon you’ll have an entire fleet under your control.

Barnabas has destroyed the Committee’s research facility, but his victory came at a cost: his friend Jeltor remains captive and brainwashed. He isn’t going to stand for that. He is going to find and rescue his friend, no matter what it takes. But what will he do when he has to decide between saving his friend and saving an entire planet?
