Rebels And Patriots by AG Claymore

In a declining human empire, disaster lurks just beneath the surface of public awareness. When Inspector Paul Grimm investigates a crime involving his oldest friend, he uncovers far more than a simple murder.
Beneath the thin veneer of corruption and murder lies treason on an astounding scale. Officials at the highest levels of government are willing to betray the empire to humanity’s ancient enemy.
Paul joins forces with Colonel Julia Urbica of the Imperial Marines and they realize they’ve only been scratching the surface. The traitors have exposed a fatal weakness in the empire and, in the desperate race that follows, it must be protected from the enemy if humanity is to remain free.
