The Year’s Best Science Fiction: Tenth Annual Collection

by Gardner Dozois

  * * *

  Assembled on Phobos, the inner satellite of Mars, ATLAS was little more than a set of rocket engines attached to propellant tanks holding 100,000 tons of hydrogen. Though its fusion drive could generate far less thrust than the primitive missile that had carried Yuri Gagarin into space, it could run continuously not merely for minutes but for weeks. Even so, the effect on the asteroid would be trivial, a velocity change of a few centimeters per second. Yet that might be sufficient to deflect Kali from its fatal orbit during the months while it was still falling earthward.

  * * *

  Now that ATLAS’s propellant tanks, control systems and thrusters had been securely mounted on Kali, it looked as if some lunatic had built an oil refinery on an asteroid. Captain Singh was exhausted, as were all the crew members, after days of assembly and checking. Yet he felt a warm glow of achievement: they had done everything that was expected of them, the countdown was going smoothly, and the rest was up to ATLAS.

  He would have been far less relaxed had he known of the ABSOLUTE PRIORITY message racing toward him by tight infrared beam from ASTROPOL headquarters in Geneva. It would not reach Goliath for another 30 minutes. And by then it would be much too late.

  * * *

  At about T minus 30 minutes, Goliath had drawn away from Kali to stand well clear of the jet with which ATLAS would try to nudge it from its present course. “Like a mouse pushing an elephant,” one media person had described the operation. But in the frictionless vacuum of space, where momentum could never be lost, even one mousepower would be enough if applied early and over a sufficient length of time.

  The group of officers waiting quietly on the bridge did not expect to see anything spectacular: the plasma jet of the ATLAS drive would be far too hot to produce much visible radiation. Only the telemetry would confirm that ignition had started and that Kali was no longer an implacable juggernaut, wholly beyond the control of humanity.

  There was a brief round of cheering and a gentle patter of applause as the string of zeros on the accelerometer display began to change. The feeling on the bridge was one of relief rather than exultation. Though Kali was stirring, it would be days and weeks before victory was assured.

  And then, unbelievably, the numbers dropped back to zero. Seconds later, three simultaneous audio alarms sounded. All eyes were suddenly fixed on Kali and the ATLAS booster which should be nudging it from its present course. The sight was heartbreaking: the great propellant tanks were opening up like flowers in a time-lapse movie, spilling out the thousands of tons of reaction mass that might have saved the Earth. Wisps of vapor drifted across the face of the asteroid, veiling its cratered surface with an evanescent atmosphere.

  Then Kali continued along its path, heading inexorably toward a fiery collision with the Earth.

  * * *

  Captain Singh was alone in the large, well-appointed cabin that had been his home for longer than any other place in the solar system. He was still dazed but was trying to make his peace with the universe.

  He had lost, finally and forever, all that he loved on Earth. With the decline of the nuclear family, he had known many deep attachments, and it had been hard to decide who should be the mothers of the two children he was permitted. A phrase from an old American novel (he had forgotten the author) kept coming into his mind: “Remember them as they were—and write them off.” The fact that he himself was perfectly safe somehow made him feel worse; Goliath was in no danger whatsoever, and still had all the propellant it needed to rejoin the shaken survivors of humanity on the Moon or Mars.

  Well, he had many friendships—and one that was much more than that—on Mars; this was where his future must lie. He was only 102, with decades of active life ahead of him. But some of the crew had loved ones on the Moon; he would have to put Goliath’s destination to the vote.

  Ship’s Orders had never covered a situation like this.

  I still don’t understand,” said the chief engineer, “why that explosive cord wasn’t detected on the preflight check-out.”

  “Because that Reborn fanatic could have hidden it easily—and no one would have dreamed of looking for such a thing. Pity ASTROPOL didn’t catch him while he was still on Phobos.”

  “But why did they do it? I can’t believe that even Chrislamic crazies would want to destroy the Earth.”

  “You can’t argue with their logic—if you accept their premises. God, Allah, is testing us, and we mustn’t interfere. If Kali misses, fine. If it doesn’t, well, that’s part of Her bigger plan. Maybe we’ve messed up Earth so badly that it’s time to start over. Remember that old saying of Tsiolkovski’s: ‘Earth is the cradle of humankind, but you cannot live in the cradle forever.’ Kali could be a sign that it’s time to leave.”

  The captain held up his hand for silence.

  “The only important question now is, Moon or Mars? They’ll both need us. I don’t want to influence you” (that was hardly true; everyone knew where he wanted to go), “so I’d like your views first.”

  The first ballot was Mars 6, Moon 6, Don’t know I, captain abstaining.

  Each side was trying to convert the single “Don’t know” when David spoke.

  “There is an alternative.”

  “What do you mean?” Captain Singh demanded, rather brusquely.

  “It seems obvious. Even though ATLAS is destroyed, we still have a chance of saving the Earth. According to my calculations, Goliath has just enough propellant to deflect Kali—if we start thrusting against it immediately. But the longer we wait, the less the probability of success.”

  There was a moment of stunned silence on the bridge as everyone asked the question, “Why didn’t I think of that?” and quickly arrived at the answer.

  David had kept his head, if one could use so inappropriate a phrase, while all the humans around him were in a state of shock. There were some compensations in being a Legal Person (Nonhuman). Though David could not know love, neither could he know fear. He would continue to think logically, even to the edge of doom.

  With any luck, thought Captain Singh, this is my last broadcast to Earth. I’m tired of being a hero, and a slightly premature one at that. Many things could still go wrong, as indeed they already have …

  “This is Captain Singh, space tug Goliath. First of all, let me say how glad we are that the Elders of Chrislam have identified the saboteurs and handed them over to ASTROPOL.

  “We are now 50 days from Earth, and we have a slight problem. This one, I hasten to add, will not affect our new attempt to deflect Kali into a safe orbit. I note that the news media are calling this deflection Operation Deliverance. We like the name, and hope to live up to it, but we still cannot be absolutely certain of success. David, who appreciates all the goodwill messages he has received, estimates that the probability of Kali impacting Earth is still 10% …

  “We had intended to keep just enough propellant reserve to leave Kali shortly before encounter and go into a safer orbit, where our sister ship Titan could rendezvous with us. But that option is now closed. While Goliath was pushing against Kali at maximum drive, we broke through a weak point in the crust. The ship wasn’t damaged, but we’re stuck! All attempts to break away have failed.

  “We’re not worried, and it may even be a blessing in disguise. Now we’ll use the whole of our remaining propellant to give one final nudge. Perhaps that will be the last drop that’s needed to do the job.

  “So we’ll ride Kali past Earth, and wave to you from a comfortable distance, in just 50 days.”

  It would be the longest 50 days in the history of the world.

  Now the huge crescent of the Moon spanned the sky, the jagged mountain peaks along the terminator burning with the fierce light of the lunar dawn. But the dusty plains still untouched by the sun were not completely dark; they were glowing faintly in the light reflected from Earth’s clouds and continents. And scattered here and there across that once dea
d landscape were the glowing fireflies that marked the first permanent settlements humankind had built beyond the home planet. Captain Singh could easily locate Clavius Base, Port Armstrong, Plato City. He could even see the necklace of faint lights along the Translunar Railroad, bringing its precious cargo of water from the ice mines at the South Pole.

  Earth was now only five hours away.

  * * *

  Kali entered Earth’s atmosphere soon after local midnight, 200 km above Hawaii. Instantly, the gigantic fireball brought a false dawn to the Pacific, awakening the wildlife on its myriad islands. But few humans had been asleep this night of nights, except those who had sought the oblivion of drugs.

  Over New Zealand, the heat of the orbiting furnace ignited forests and melted the snow on mountaintops, triggering avalanches into the valleys beneath. But the human race had been very, very lucky: the main thermal impact as Kali passed the Earth was on the Antarctic, the continent that could best absorb it. Even Kali could not strip away all the kilometers of polar ice, but it set in motion the Great Thaw that would change coastlines all around the world.

  No one who survived hearing it could ever describe the sound of Kali’s passage; none of the recordings were more than feeble echoes. The video coverage, of course, was superb, and would be watched in awe for generations to come. But nothing could ever compare with the fearsome reality.

  Two minutes after it had sliced into the atmosphere, Kali reentered space. Its closest approach to Earth had been 60 km. In that two minutes, it took 100,000 lives and did $1 trillion worth of damage.

  * * *

  Goliath had been protected from the fireball by the massive shield of Kali itself; the sheets of incandescent plasma streamed harmlessly overhead. But when the asteroid smashed into Earth’s blanket of air at more than 100 times the speed of sound, the colossal drag forces mounted swiftly to five, 10, 20 gravities—and peaked at a level far beyond anything that machines or flesh could withstand.

  Now indeed Kali’s orbit had been drastically changed; never again would it come near Earth. On its next return to the inner solar system, the swifter spacecraft of a later age would visit the crumpled wreckage of Goliath and bear reverently homeward the bodies of those who had saved the world.

  Until the next encounter.

  GROWNUPS

  Ian R. MacLeod

  New British writer Ian R. MacLeod has been one of the most talked-about young writers of the ‘90s, publishing a slew of strong stories in the first three years of the decade in Interzone, Isaac Asimov’s Science Fiction Magazine, Weird Tales, Amazing, and The Magazine of Fantasy & Science Fiction, among other markets. Several of those stories made the cut for one or another of the various “Best of the Year” anthologies, including appearances here in our Eight and Ninth Annual Collections. In 1990, in fact, he appeared in three different Best of the Year anthologies with three different stories, certainly a rare distinction. He has yet to produce a novel, but it is being eagerly awaited by genre insiders, and as he has recently given up his day job to write full-time; perhaps we won’t have long to wait. MacLeod is in his early thirties, and lives with his wife and baby daughter in the West Midlands of England.

  In the disquieting story that follows, he takes us to a world that’s very like our own—except for all the ways that count the most—to relate one of the most bizarre coming-of-age stories ever written.

  Bobby finally got around to asking Mum where babies came from on the evening of his seventh birthday. It had been hot all day, and the grownups and a few of the older children who had come to his party were still outside on the lawn. He could hear their talk and evening birdsong through his open window as Mum closed the curtains. She leaned down to kiss his forehead. She’d been drinking since the first guests arrived before lunch and her breath smelt like windfall apples. Now seemed as a good a time as any. As she turned towards the door, he asked his question. It came out as a whisper, but she heard, and frowned for a moment before she smiled.

  “You children always want to know too soon,” she said. “I was the same, believe me, Bobby. But you must be patient. You really must.”

  Bobby knew enough about grownups to realize that it was unwise to push too hard. So he forced himself to yawn and blink slowly so she would think he was truly sleepy. She patted his hand.

  After his door had clicked shut, after her footsteps had padded down the stairs, Bobby slid out of bed. Ignoring the presents piled in the corner by the closet—robots with sparking eyes, doll soldiers, and submarines—he peered from the window. They lived at the edge of town, where rooftops dwindled to green hills and the silver curl of the river. He watched Mum emerge from the French windows onto the wide lawn below. She stopped to say something to Dad as he sat lazing in a deckchair with the other men, a beercan propped against his crotch. Then she took a taper from the urn beside the barbecue and touched it to the coals. She proceeded to light the lanterns hanging from the boughs of the cherry trees.

  The whole garden filled with stars. After she had lit the last lantern, Mum put the taper to her mouth and extinguished it with her tongue. Then she rejoined the women gossiping on the white wrought iron chairs. The remaining children were all leaving for home. Cars were starting up, turning out from the shaded drive. Bobby heard his brother Tony call goodnight to the grownups and thunder up the stairs. He tensed in case Tony should decide to look in on him before he went to bed, but relaxed after the toilet had flushed and Tony’s bedroom door had slammed. It was almost night. Bobby knew that his window would show as no more than a darker square against the wall of the house. He widened the parting in the curtain.

  He loved to watch the grownups when they thought they were alone. It was a different world. One day, Mum had told him often enough, one day, sweet little Bobby, you’ll understand it all, touching his skin as she spoke with papery fingers. But give it time, my darling one, give it time. Being a grownup is more wonderful than you children could ever imagine. More wonderful. Yes, my darling. Kissing him on the forehead and each eye and then his mouth, the way she did when she got especially tender.

  Bobby gazed down at the grownups. They had that loose look that came when the wine and the beer had gone down well and there was more to come, when the night was warm and the stars mirrored the lanterns. Dad raised his can from his crotch to his lips. One of the men beside him made a joke and the beer spluttered down Dad’s chin, gleaming for a moment before he wiped it away. The men always talked like this, loud between bursts of silence, whilst the women’s voices—laughing serious sad—brushed soft against the night. Over by the trellis archway that led by the garbage cans to the front, half a dozen uncles sat in the specially wide deckchairs that Dad kept for them behind the mower in the shed.

  Bobby couldn’t help staring at the uncles. They were all grossly fat. There was Uncle Stan, Uncle Harold, and, of course, his own Uncle Lew. Bobby saw with a certain pride that Lew was the biggest. His tie was loose and his best shirt strained like a full sail across his belly. Like all the uncles, Lew lived alone, but Dad or the father of one of the other families Lew was uncle to was always ready to take the car down on a Saturday morning, paint the windows of his house, or see to the lawn. In many ways, Bobby thought, it was an ideal life. People respected uncles. Even more than their girth required, they stepped aside from them in the street. But at the same time, his parents were often edgy when Lew was around, uncharacteristically eager to please. Sometimes late in the night, Bobby had heard the unmistakable clatter of his van on the gravel out front, Mum and Dad’s voices whispering softly excited in the hall. Gazing at Lew, seated with the other uncles, Bobby remembered how he had dragged him to the moist folds of his belly, rumbling Won’t You Just Look At This Sweet Kid? His yeasty aroma came back like the aftertaste of bad cooking.

  Someone turned the record player on in the lounge. Sibilant music drifted like smoke. Some of the grownups began to dance. Women in white dresses blossomed as they turned, and the men were darkly quick. The music
and the sigh of their movement brushed against the humid night, coaxed the glow of the lanterns, silvered the rooftops and the stars.

  The dancing quickened, seeking a faster rhythm inside the slow beat. Bobby’s eyes fizzed with sleep. He thought he saw grownups floating heartbeat on heartbeat above the lawn. Soon they were leaping over the lanterned cherry trees, flying, pressing close to his window with smiles and waves, beckoning him to join them. Come out and play, Bobby, out here amid the stars. The men darted like eels, the women did high kicks across the rooftop, their dresses billowing coral frills over their heads. The uncles bobbed around the chimney like huge balloons.

  When Bobby awoke, the lanterns were out. There was only darkness, summer chill.

  As he crawled back to bed, a sudden sound made him freeze. Deep and feral, some kind of agony that was neither pain nor grief, it started loud then came down by notches to a stuttering sob. Bobby unfroze when it ended and hauled the blankets up to his chin. Through the bedroom wall, he could hear the faint mutter of Dad’s voice, Mum’s half-questioning reply. Then Uncle Lew saying goodnight. Slow footsteps down the stairs. The front door slam. Clatter of an engine coming to life.

  Sigh of gravel.

  Silence.

  * * *

  Bobby stood at the far bank of the river. His hands clenched and unclenched. Three years had passed. He was now ten; his brother Tony was sixteen.
