Captain Brandon was a pioneer. He explored the far reaches of space and reported back on how things were out there. So it was pretty disquieting to find out that the "far reaches of space" knew more about what went on at home than he did.
The customs officer isn't even human, so it feels like just another R&R, another halting conversation carried on in ugly trade-speak, another bewilderment of queues and luggage carousels.

In a future time, the solar system is powered by one energy source, controlled by one huge organisation, which has plans to use this control to dominate the planets. Unknown to them, a couple of maverick scientists accidentally develop a completely new form of energy supply and threaten the corporation's monopoly. Naturally, the corporation can't allow this to happen... A stunning story about the manipulation of pure energy, climaxing in interstellar conflict.
