The G.O.D. Factor a novella by Rachel V. Olivier
During one of Monica’s shifts, a dormant A.I., part of an old starship class known as Galactic Orbital Dreadnaughts, or G.O.D., that Engineer Belukas thought was safely turned off, wakes up. After years of isolation and hibernation it is more insane and lonely than many of its cohorts had been during the era when they had been used in a galactic war. It truly thinks it is God. It takes over the ship and decides it’s time to go bring order to the rest of the universe for the good of humankind. It’s up to Monica to try to get her other crewmates out of an A.I.-imposed deep-freeze stasis, and together with them take back the ship and save themselves and known civilization.
If it isn’t already too late.
