Jet Black and the Incubator

A gigantic alien spaceship is racing across the galaxy; it isn’t slowing down and it won’t respond to any calls: what’s Jet and the crew to do before an accident happens? Get aboard, but where is everybody: asleep? And where have all the rocks littering the floors come from? Maybe the answer is to find out what’s prowling around the dark and silent passageways before it finds them.
