From publisher blurb:
During the travelers various journeys they occasionally wander into places only to discover that fuel is scarce and a return trip might not be possible without a place to stop for fuel. Occasionally even systems with gas giants might not provide the means of refueling. Atmospheric storms can sometimes prevent ships from fueling in that manner. Local pirates often lurk near gas giants to catch the unwary.
Fortunately, however, there are sometimes places such as Station GH-34I. This solitary station floats in a system in the Sonora sector waiting for ships that need refueling. Like days in the past this is a full service station. They not only refuel the ship but wipe the windows and check under the hood. All for 20% less that the going rate for fuel in the sector.
Is it generosity? Or do these aliens have ulterior motives? One can never tell in the frontiers of space.
