内容简介：
Anyone looking at the Great Cygnus Loop for the first, second or even the twentieth time could not fail to be impressed. Anyone looking a bit closer could not fail to see a little black hole. Then they would go away, as far away as possible. And anyone wondering if there was something else out there, something that could 'eat' two perfectly good spaceships and their crews, would be perfectly correct. And anyone thinking that The Company boss, a confused girl, an overconfident pilot, a master of time and a couple of particularly clever robots could find out what happened, would be wrong. And everyone should be advised: Do not call them robots... and do not annoy the dragons.
