Defeated at the Battle for Terra Two, the cyborg AIs regroup to destroy mankind. Commodore Detrelna and the battle cruiser Implacable are sent into Quadrant Blue 9 for the only weapon that can stop them. Implacable’s crew aren’t optimistic—it’s been 3,000 years since a ship came home from Blue 9. Then they meet what’s been waiting for them. (2011 revision of original Tor Books edition.)
