Medusa in the Graveyard : Book Two of the Medusa Cycle

Oichi Angelis, along with her fellow insurgents, head for the planet called Graveyard. Ancient, sentient, alien starships wait for them - three A.I.’s so powerful they remain aware even in self-imposed sleep. The race that made them are dead, but Oichi's people were engineered with this ancient DNA. A delegation must journey to the heart of Graveyard and be judged by the Three. Before they're done, they will discover that weapons are the least of what the ships have to offer.
