We defeated the invading death machines. But at a devastating cost, with smoldering radioactive craters on Mars, shattered moon-domes around Jupiter and floating junk where Saturn's satellite cities used to orbit. We know more killing machines are coming and that the ultimate outcome seems hopeless. To win this war, we need more warships, more soldiers, and a way to take the fight to the enemy. By analyzing a testy AI probe, Jon Hawkins discovers a secret: the whereabouts of a giant AI battle station, one protecting a factory planet 17.2 light-years from Earth. Jon has to convince a defensive Premier Benz and the hostile Earth government to join him. A human flotilla has the lonely task of traveling through hyperspace to defeat the arrogant AIs in one of their own star systems. The fate of the human race rests on the sacrifice and courage of Jon Hawkins and his friends. A.I. Battle Station is the fourth book in the A.I. Series, a novel of military science fiction by best-selling author Vaughn Heppner. The series starts with book 1, A.I. Destroyer.
