"Amid an uneasy peace between the Autonomists and the Terrans, Ariane and her partner, Matt, have discovered alien ruins on a remote moon--ruins that bear evidence of an ancient and highly advanced technology. But their discovery has drawn the interest of high-stakes players from every corner of the universe--including that of the rogue leader of a fringe Terran sect. His family was destroyed by alien technology, and to avenge them he's managed to get his hands on a temporal-distortion weapon. Now Ari must find a way to stop him before they all become ancient history."--p. [4] of cover.
