It has been generations since the Earth survived the alien invasion. Politicians have cast a greedy eye on the funding of unused defenses, eyeing the reallocation of the funds as a way to pave their path to reelection.

Young Jock MacAlister's life long dream comes true with his assignment to ADS 1437, the last operational Asteroid Defense Station. The capture of an alien scout vessel changes everything. Jock is thrust into a prominent role in planning Earth's defense. He must overcome personal tragedy, political corruption, and devastating treachery to build the forces needed to save the Earth. Along the way, something unexpected takes root, something crucial to Humanity surviving as a greater struggle between good and evil follows Humanity to the stars.
