Vengeance is a Wheel | Orion the Hunter Book 1

A marshal of the newly minted Federation of Worlds, he is a man-hunter and sworn to serve the law. Now he has returned to the world of his birth to fulfill a different oath. One made as he grew to manhood in the interment camps during the war. An oath sworn on the blood of a dead family. An oath that may leave his home world a dead husk by the time he is done.
