Lost Fleet - Beyond the Frontier - Leviathan Book 5

Two Syndicate World star systems have fallen prey to a mysterious fleet of warships controlled entirely by artificial intelligence. The warships are no mystery to Geary. He knows they were developed by his government to ensure security, but malfunctioned. If the Syndics learn the truth, the war with the Alliance will resume with a vengeance. As the government attempts to conceal the existence of the A.I. warships - and its role in their creation-Geary must track the ships to their secret base in the supposedly mythical Unity Alternate star system and end the conflict-at any cost.
