Starflake Aboard the Doomed Ships

The luxury passenger starship, Alpha Centuri, accidentally pulls a ship out of an antimatter universe and the ship, called the Beta Centuri, is linked to the Alpha. The two ships, a gravity ship and an anti-gravity ship, are held to each other in perfect balance, but if either ship waivers even a hair from this unholy alliance then they will touch and annihilate each other. Hundreds of lives are at stake.
Along comes Starflake in her Trog, taxi cyborg. She is a Cosmic Sprite, a pixyish creature who lives on radiation making it easy to bath her in either matter or antimatter radiation. As an ambassador between the two ships, she becomes the agent of hope, however, there are serious problems toward a peaceful solution in the guise of mutineers, madmen, doppelgangers, and hit men with the ability to see and travel through walls. All of them want to sabotage her mission or at least... kill her.
