The Lost Artifact (Unabridged‪)‬

Star Watch defeated the Swarm Invasion Fleet, but at a terrible cost in destroyed star systems, smashed battleships and billions of dead. In the aftermath of the costly victory, chaos threatens as worlds leave the Commonwealth of Planets, face mass starvation or succumb to increased piracy. The war against the Swarm Imperium has just begun. Humanity needs unity or each planet will fall alone. Brigadier O'Hara of Star Watch Intelligence stumbles onto a secret conspiracy. Someone is trying to destroy the Commonwealth from within, and they have an alien artifact of incredible power. O'Hara summons Captain Maddox. Although she fears to lose him, she knows that Maddox and his crew have the best chance of finding the hidden enemy. If the captain fails, the Commonwealth will be powerless to stop its destruction. What O'Hara doesn't know--it would probably break her heart if she did--is that she has just sent Maddox into the most harrowing battle of his career. THE LOST ARTIFACT is the eighth book in the LOST STARSHIP SERIES.
