Heart and Sol. Echoes of Sol, #6

Dead in the water. Never, in its century of service had the Lenore been dead in the water. But now she was floating adrift, and that was the least of Jack's worries. The free-roaming kitten, the would-be rapist, and the budding romance were all more alarming to Jack. When the Lenore finally limps into port, Jack finds a job ready and waiting despite the fact Bit had an active hand in the destruction of an entire space station.
Now the crew of the Lenore must reach the far end of the colonized galaxy and save an asteroid mine from foundering.
