The Best Science Fiction and Fantasy of the Year-II

by Jonathan Strahan

  From across the light-years, an elaborate sequence of gamma ray pulses fell upon the panel. These pulses were the needle's true payload, the passengers for whom it had merely prepared the way, transmitted in its wake four years after its launch. The panel decoded and stored the data, and the army of nanomachines set to work again, this time following a far more elaborate blueprint. The miners were forced to look farther afield to find all the elements that were needed, while the assemblers laboured to reach their goal through a sequence of intermediate stages, carefully designed to protect the final product from the vagaries of the local chemistry and climate.

  After three months' work, two small fusion-powered spacecraft sat in the snow. Each one held a single occupant, waking for the first time in their freshly minted bodies, yet endowed with memories of an earlier life.

  Joan switched on her communications console. Anne appeared on the screen, three short pairs of arms folded across her thorax in a posture of calm repose. They had both worn virtual bodies with the same anatomy before, but this was the first time they had become Noudah in the flesh.

  "We're here. Everything worked," Joan marvelled. The language she spoke was not her own, but the structure of her new brain and body made it second nature.

  Anne said, "Now comes the hard part."

  "Yes." Joan looked out from the spacecraft's cockpit. In the distance, a fissured blue-grey plateau of water ice rose above the snow. Nearby, the nanomachines were busy disassembling the gamma ray receiver. When they had erased all traces of their handiwork they would wander off into the snow and catalyse their own destruction.

  Joan had visited dozens of planet-bound cultures in the past, taking on different bodies and languages as necessary, but those cultures had all been plugged into the Amalgam, the metacivilisation that spanned the galactic disk. However far from home she'd been, the means to return to familiar places had always been close at hand. The Noudah had only just mastered interplanetary flight, and they had no idea that the Amalgam existed. The closest node in the Amalgam's network was seven light-years away, and even that was out of bounds to her and Anne now: they had agreed not to risk disclosing its location to the Noudah, so any transmission they sent could be directed only to a decoy node that they'd set up more than twenty light-years away.

  "It will be worth it," Joan said.

  Anne's Noudah face was immobile, but chromatophores sent a wave of violet and gold sweeping across her skin in an expression of cautious optimism. "We'll see." She tipped her head to the left, a gesture preceding a friendly departure.

  Joan tipped her own head in response, as if she'd been doing so all her life. "Be careful, my friend," she said.

  "You too."

  Anne's ship ascended so high on its chemical thrusters that it shrank to a speck before igniting its fusion engine and streaking away in a blaze of light. Joan felt a pang of loneliness; there was no predicting when they would be reunited.

  Her ship's software was primitive; the whole machine had been scrupulously matched to the Noudah's level of technology. Joan knew how to fly it herself if necessary, and on a whim she switched off the autopilot and manually activated the ascent thrusters. The control panel was crowded, but having six hands helped.

  The world the Noudah called home was the closest of the system's five planets to their sun. The average temperature was one hundred and twenty degrees Celsius, but the high atmospheric pressure allowed liquid water to exist across the entire surface. The chemistry and dynamics of the planet's crust had led to a relatively flat terrain, with a patchwork of dozens of disconnected seas but no globe-spanning ocean. From space, these seas appeared as silvery mirrors, bordered by a violet and brown tarnish of vegetation.

  The Noudah were already leaving their most electromagnetically promiscuous phase of communications behind, but the short-lived oasis of Amalgam-level technology on Baneth, the gas giant's moon, had had no trouble eavesdropping on their chatter and preparing an updated cultural briefing which had been spliced into Joan's brain.

  The planet was still divided into the same eleven political units as it had been fourteen years before, the time of the last broadcasts that had reached the node before Joan's departure. Tira and Ghahar, the two dominant nations in terms of territory, economic activity, and military power, also occupied the vast majority of significant Niah archaeological sites.

  Joan had expected that they'd be noticed as soon as they left Baneth—the exhaust from their fusion engines glowed like the sun—but their departure had triggered no obvious response, and now that they were coasting they'd be far harder to spot. As Anne drew closer to the homeworld, she sent a message to Tira's traffic control centre. Joan tuned in to the exchange.

  "I come in peace from another star," Anne said. "I seek permission to land."

  There was a delay of several seconds more than the light-speed lag, then a terse response. "Please identify yourself and state your location."

  Anne transmitted her coordinates and flight plan.

  "We confirm your location, please identify yourself."

  "My name is Anne. I come from another star."

  There was a long pause, then a different voice answered. "If you are from Ghahar, please explain your intentions."

  "I am not from Ghahar."

  "Why should I believe that? Show yourself."

  "I've taken the same shape as your people, in the hope of living among you for a while." Anne opened a video channel and showed them her unremarkable Noudah face. "But there's a signal being transmitted from these coordinates that might persuade you that I'm telling the truth." She gave the location of the decoy node, twenty light-years away, and specified a frequency. The signal coming from the node contained an image of the very same face.

  This time, the silence stretched out for several minutes. It would take a while for the Tirans to confirm the true distance of the radio source.

  "You do not have permission to land. Please enter this orbit, and we will rendezvous and board your ship."

  Parameters for the orbit came through on the data channel. Anne said, "As you wish."

  Minutes later, Joan's instruments picked up three fusion ships being launched from Tiran bases. When Anne reached the prescribed orbit, Joan listened anxiously to the instructions the Tirans issued. Their tone sounded wary, but they were entitled to treat this stranger with caution, all the more so if they believed Anne's claim.

  Joan was accustomed to a very different kind of reception, but then the members of the Amalgam had spent hundreds of millennia establishing a framework of trust. They also benefited from a milieu in which most kinds of force had been rendered ineffectual; when everyone had backups of themselves scattered around the galaxy, it required a vastly disproportionate effort to inconvenience someone, let alone kill them. By any reasonable measure, honesty and cooperation yielded far richer rewards than subterfuge and slaughter.

  Nonetheless, each individual culture had its roots in a biological heritage that gave rise to behaviour governed more by ancient urges than contemporary realities, and even when they mastered the technology to choose their own nature, the precise set of traits they preserved was up to them. In the worst case, a species still saddled with inappropriate drives but empowered by advanced technology could wreak havoc. The Noudah deserved to be treated with courtesy and respect, but they did not yet belong in the Amalgam.

  The Tirans' own exchanges were not on open channels, so once they had entered Anne's ship Joan could only guess at what was happening. She waited until two of the ships had returned to the surface, then sent her own message to Ghahar's traffic control.

  "I come in peace from another star. I seek permission to land."

  The Ghahari allowed Joan to fly her ship straight down to the surface. She wasn't sure if this was because they were more trusting, or if they were afraid that the Tirans might try to interfere if she lingered in orbit.

  The landing site was a bare plain of chocolate-
coloured sand. The air shimmered in the heat, the distortions intensified by the thickness of the atmosphere, making the horizon waver as if seen through molten glass. Joan waited in the cockpit as three trucks approached; they all came to a halt some twenty metres away. A voice over the radio instructed her to leave the ship; she complied, and after she'd stood in the open for a minute, a lone Noudah left one of the trucks and walked towards her.

  "I'm Pirit," she said. "Welcome to Ghahar." Her gestures were courteous but restrained.

  "I'm Joan. Thank you for your hospitality."

  "Your impersonation of our biology is impeccable." There was a trace of skepticism in Pirit's tone; Joan had pointed the Ghahari to her own portrait being broadcast from the decoy node, but she had to admit that in the context her lack of exotic technology and traits would make it harder to accept the implications of that transmission.

  "In my culture, it's a matter of courtesy to imitate one's hosts as closely as possible."

  Pirit hesitated, as if pondering whether to debate the merits of such a custom, but then rather than quibbling over the niceties of interspecies etiquette she chose to confront the real issue head-on. "If you're a Tiran spy, or a defector, the sooner you admit that the better."

  "That's very sensible advice, but I'm neither."

  The Noudah wore no clothing as such, but Pirit had a belt with a number of pouches. She took a handheld scanner from one and ran it over Joan's body. Joan's briefing suggested that it was probably only checking for metal, volatile explosives, and radiation; the technology to image her body or search for pathogens would not be so portable. In any case, she was a healthy, unarmed Noudah down to the molecular level.

  Pirit escorted her to one of the trucks, and invited her to recline in a section at the back. Another Noudah drove while Pirit watched over Joan. They soon arrived at a small complex of buildings a couple of kilometres from where the ship had touched down. The walls, roofs, and floors of the buildings were all made from the local sand, cemented with an adhesive that the Noudah secreted from their own bodies.

  Inside, Joan was given a thorough medical examination, including three kinds of full-body scans. The Noudah who examined her treated her with a kind of detached efficiency devoid of any pleasantries; she wasn't sure if that was their standard bedside manner, or a kind of glazed shock at having been told of her claimed origins.

  Pirit took her to an adjoining room and offered her a couch. The Noudah anatomy did not allow for sitting, but they liked to recline.

  Pirit remained standing. "How did you come here?" she asked.

  "You've seen my ship. I flew it from Baneth."

  "And how did you reach Baneth?"

  "I'm not free to discuss that," Joan replied cheerfully.

  "Not free?" Pirit's face clouded with silver, as if she were genuinely perplexed.

  Joan said, "You understand me perfectly. Please don't tell me there's nothing you're not free to discuss with me."

  "You certainly didn't fly that ship twenty light-years."

  "No, I certainly didn't."

  Pirit hesitated. "Did you come through the Cataract?" The Cataract was a black hole, a remote partner to the Noudah's sun; they orbited each other at a distance of about eighty billion kilometres. The name came from its telescopic appearance: a dark circle ringed by a distortion in the background of stars, like some kind of visual aberration. The Tirans and Ghahari were in a race to be the first to visit this extraordinary neighbour, but as yet neither of them were quite up to the task.

  "Through the Cataract? I think your scientists have already proven that black holes aren't shortcuts to anywhere."

  "Our scientists aren't always right."

  "Neither are ours," Joan admitted, "but all the evidence points in one direction: black holes aren't doorways, they're shredding machines."

  "So you travelled the whole twenty light-years?"

  "More than that," Joan said truthfully, "from my original home. I've spent half my life travelling."

  "Faster than light?" Pirit suggested hopefully.

  "No. That's impossible."

  They circled around the question a dozen more times, before Pirit finally changed her tune from how to why?

  "I'm a xenomathematician," Joan said. "I've come here in the hope of collaborating with your archaeologists in their study of Niah artifacts."

  Pirit was stunned. "What do you know about the Niah?"

  "Not as much as I'd like to." Joan gestured at her Noudah body. "As I'm sure you've already surmised, we've listened to your broadcasts for some time, so we know pretty much what an ordinary Noudah knows. That includes the basic facts about the Niah. Historically they've been referred to as your ancestors, though the latest studies suggest that you and they really just have an earlier common ancestor. They died out about a million years ago, but there's evidence that they might have had a sophisticated culture for as long as three million years. There's no indication that they ever developed space flight. Basically, once they achieved material comfort, they seem to have devoted themselves to various art forms, including mathematics."

  "So you've travelled twenty light-years just to look at Niah tablets?" Pirit was incredulous.

  "Any culture that spent three million years doing mathematics must have something to teach us."

  "Really?" Pirit's face became blue with disgust. "In the ten thousand years since we discovered the wheel, we've already reached halfway to the Cataract. They wasted their time on useless abstractions."

  Joan said, "I come from a culture of spacefarers myself, so I respect your achievements. But I don't think anyone really knows what the Niah achieved. I'd like to find out, with the help of your people."

  Pirit was silent for a while. "What if we say no?"

  "Then I'll leave empty-handed."

  "What if we insist that you remain with us?"

  "Then I'll die here, empty-handed." On her command, this body would expire in an instant; she could not be held and tortured.

  Pirit said angrily, "You must be willing to trade something for the privilege you're demanding!"

  "Requesting, not demanding," Joan insisted gently. "And what I'm willing to offer is my own culture's perspective on Niah mathematics. If you ask your archaeologists and mathematicians, I'm sure they'll tell you that there are many things written in the Niah tablets that they don't yet understand. My colleague and I"—neither of them had mentioned Anne before, but Joan was sure that Pirit knew all about her—"simply want to shed as much light as we can on this subject."

  Pirit said bitterly, "You won't even tell us how you came to our world. Why should we trust you to share whatever you discover about the Niah?"

  "Interstellar travel is no great mystery," Joan countered. "You know all the basic science already; making it work is just a matter of persistence. If you're left to develop your own technology, you might even come up with better methods than we have."

  "So we're expected to be patient, to discover these things for ourselves . . . but you can't wait a few centuries for us to decipher the Niah artifacts?"

  Joan said bluntly, "The present Noudah culture, both here and in Tira, seems to hold the Niah in contempt. Dozens of partially excavated sites containing Niah artifacts are under threat from irrigation projects and other developments. That's the reason we couldn't wait. We needed to come here and offer our assistance, before the last traces of the Niah disappeared forever."

  Pirit did not reply, but Joan hoped she knew what her interrogator was thinking: Nobody would cross twenty light-years for a few worthless scribblings. Perhaps we've underestimated the Niah. Perhaps our ancestors have left us a great secret, a great legacy. And perhaps the fastest—perhaps the only—way to uncover it is to give this impertinent, irritating alien exactly what she wants.

  The sun was rising ahead of them as they reached the top of the hill. Sando turned to Joan, and his face became green with pleasure. "Look behind you," he said.

  Joan did as he as
ked. The valley below was hidden in fog, and it had settled so evenly that she could see their shadows in the dawn light, stretched out across the top of the fog layer. Around the shadow of her head was a circular halo like a small rainbow.

  "We call it the Niah's light," Sando said. "In the old days, people used to say that the halo proved that the Niah blood was strong in you."

  Joan said, "The only trouble with that hypothesis being that you see it around your head . . .and I see it around mine." On Earth, the phenomenon was known as a "glory." The particles of fog were scattering the sunlight back towards them, turning it one hundred and eighty degrees. To look at the shadow of your own head was to face directly away from the sun, so the halo always appeared around the observer's shadow.

  "I suppose you're the final proof that Niah blood has nothing to do with it," Sando mused.

  "That's assuming I'm telling you the truth, and I really can see it around my own head."

  "And assuming," Sando added, "that the Niah really did stay at home, and didn't wander around the galaxy spreading their progeny."

  They came over the top of the hill and looked down into the adjoining riverine valley. The sparse brown grass of the hillside gave way to a lush violet growth closer to the water. Joan's arrival had delayed the flooding of the valley, but even alien interest in the Niah had only bought the archaeologists an extra year. The dam was part of a long-planned agricultural development, and however tantalising the possibility that Joan might reveal some priceless insight hidden among the Niah's "useless abstractions," that vague promise could only compete with more tangible considerations for a limited time.

  Part of the hill had fallen away in a landslide a few centuries before, revealing more than a dozen beautifully preserved strata. When Joan and Sando reached the excavation site, Rali and Surat were already at work, clearing away soft sedimentary rock from a layer that Sando had dated as belonging to the Niah's "twilight" period.
