The Year's Best Science Fiction, Vol. 20

Naqi gripped a handrail and swung out behind the airship. Here the vacuum bladder overhung the gondola by only a metre, and a grilled ladder allowed her to climb around the overhang and scramble onto the flat top of the bag. She moved gingerly, bare feet against rusting rungs, doing her best not to disturb Mina. The airship rocked and creaked a little as she found her balance on the top and then was again silent and still. The churning of its motors was so quiet that Naqi had long ago filtered the sound from her experience.

All was calm, beautifully so.

In the moonlight the antenna was a single dark flower rising from the broad back of the bladder. Naqi started moving along the railed catwalk that led to it, steadying herself as she went but feeling much less vertigo than would have been the case in daytime.

Then she froze, certain that she was being watched.

Just within Naqi’s peripheral vision appeared a messenger sprite. It had flown to the height of the airship and was now shadowing it from a distance of ten or twelve metres. Naqi gasped, delighted and unnerved at the same time. Apart from dead specimens this was the first time Naqi had ever seen a sprite this close. The organism had the approximate size and morphology of a terrestrial hummingbird, yet it glowed like a lantern. Naqi recognised it immediately as a long-range packet carrier. Its belly would be stuffed with data coded into tightly packed wads of RNA, locked within microscopic protein capsomeres. The packet carrier’s head was a smooth teardrop, patterned with luminous pastel markings but lacking any other detail save for two black eyes positioned above the midline. Inside the head was a cluster of neurones, which encoded the positions of the brightest circumpolar stars. Other than that, sprites had only the most rudimentary kind of intelligence. They existed only to shift information between nodal points in the ocean when the usual chemical signalling pathways were deemed too slow or imprecise. The sprite would die when it reached its destination, consumed by microscopic organisms that would unravel and process the information stored in the capsomeres.

And yet Naqi had the acute sense that it was watching her. Not just the airship, but her, with a kind of watchful curiosity that made the hairs on the back of her neck bristle. And then-just at the point when the feeling of scrutiny had become unsettling-the sprite whipped sharply away from the airship. Naqi watched it descend back toward the ocean and then coast above the surface, bobbing now and then like a skipping stone. She remained still for several more minutes, convinced that something of significance had happened and yet also aware of how subjective the experience had been; how unimpressive it would seem if she tried to explain it to Mina tomorrow. Anyway, Mina was the one with the special bond to the ocean, wasn’t she? Mina was the one who scratched her arms at night; Mina was the one who had too high a conformal index to be allowed into the swimmer corps. It was always Mina. It was never Naqi.

The antenna’s metre-wide dish was anchored to a squat plinth inset with weatherproofed controls and readouts. It was century-old Pelican technology, like the airship and the fan. Many of the controls and displays were dead, but the unit was still able to lock onto the functioning satellites. Naqi flicked open the fan and copied the latest feeds into the fan’s remaining memory. Then she knelt down next to the plinth, propped the fan on her knees and sifted through the messages and news summaries of the last day. A handful of reports had arrived from friends in Prachuap-Pangnirtung and Umingmaktok snowflake cities, another from an old boyfriend in the swimmer corps station on Narathiwat atoll. He had sent her a list of jokes that were already in wide circulation. She scrolled down the list, grimacing more than grinning, before finally managing a half-hearted chuckle at one that had escaped her. Then there were a dozen digests from various special interest groups related to the Jugglers, along with a request from a journal editor that she critique a paper. Naqi skimmed the paper’s abstract, judging that she was probably capable of reviewing it.
