JAMES PATRICK KELLY.

James Patrick Kelly [www.jimkelly.net] wrote "Think Like a Dinosaur," a critique of the hard SF cla.s.sic, Tom G.o.dwin"s "The Cold Equations." It was the lead story in Year"s Best SF 1, and won the Hugo Award in 1996. If there was a new synthesis in 1990s hard SF, it is at the point where Gregory Benford, Kelly, and Bruce Sterling meet. Though identified with the Sycamore Hill workshop in the 1980s, the hotbed of Humanist opposition to the cyberpunks, he was also chosen as one of the original cyberpunks by Bruce Sterling for inclusion in Mirrorshades, the Cyberpunk Anthology. Much of Kelly"s fiction has a serious hard SF side that appeals broadly to all readers in the field. His novel, Wildlife, which includes his novella "Mr. Boy," appeared in 1994, and since then he has been publishing more frequent short stories. His stories are collected in Think Like a Dinosaur and Other Stories (1997), and the forthcoming Strange but Not a Stranger (2002).

"Undone" appeared in Asimov"s, with a blurb that said Kelly claims Alfred Bester and Cordwainer Smith as influences on this piece. It"s an excellent story, with a vast scale, set in the distant future, with an engaging central character, big ideas, political satire, even typographical tricks in the Bester, Ellison, and Delany tradition. SF doesn"t get more fun than this story, the capstone of this Year"s Best

The ship screamed. Its screens showed Mada that she was surrounded in threes.p.a.ce. A swarm of Utopian asteroids was closing on her, brain clans and mining DIs living in hollowed-out chunks of carbonaceous chondrite, any one of which could have mustered enough votes to abolish Mada in all ten dimensions.

"I"m going to die," the ship cried, "I"m going to die, I"m going to..."

"I"m not." Mada waved the speaker off impatiently and scanned downwhen. She saw that the Utopians had planted an ident.i.ty mine five minutes into the past that would boil her memory to vapor if she tried to go back in time to undo this trap. Upwhen, then. The future was clear, at least as far as she could see, which wasn"t much beyond next week. Of course, that was the direction they wanted her to skip. They"d be happiest making her their great-great-great-grandchildren"s problem.

The Utopians fired another spread of panic bolts. The ship tried to absorb them, but its buffers were already overflowing. Mada felt her throat tighten. Suddenly she couldn"t remember how to spell luck, and she believed that she could feel her sanity oozing out of her ears.

"So let"s skip upwhen," she said.

"You s-sure?" said the ship. "I don"t know if... how far?

"Far enough so that all of these drones will be fossils."

"I can"t just... I need a number, Mada."

A needle of fear p.r.i.c.ked Mada hard enough to make her reflexes kick. "Skip!" Her panic did not allow for the luxury of numbers. "Skip now!" Her voice was tight as a fist. "Do it!"

Time shivered as the ship surged into the empty dimensions. In three-s.p.a.ce, Mada went all wavy.

Eons pa.s.sed in a nanosecond, then she washed back into the strong dimensions and solidified.

She merged briefly with the ship to a.s.sess damage. "What have you done?" The gain in entropy was an ache in her bones.

"I-I"m sorry, you said to skip so..." The ship was still jittery.

Even though she wanted to kick its sensorium in, she bit down hard on her anger. They had both made enough mistakes that day. "That"s all right," she said, "we can always go back. We just have to figure out when we are. Run the star charts."

two-tenths of a spin

The ship took almost three minutes to get its charts to agree with its navigation screens-a bad sign.

Reconciling the data showed that it had skipped forward in time about two-tenths of a galactic spin.

Almost twenty million years had pa.s.sed on Mada"s home world of Trueborn, time enough for its crust to fold and buckle into new mountain ranges, for the Green Sea to bloom, for the glaciers to march and melt. More than enough time for everything and everyone Mada had ever loved-or hated-to die, turn to dust and blow away.

Whiskers trembling, she checked downwhen. What she saw made her lose her perch and float aimlessly away from the command mod"s screens. There had to be something wrong with the ship"s air. It settled like dead, wet leaves in her lungs. She ordered the ship to check the mix.

The ship"s deck flowed into an enormous plastic hand, warm as blood. It cupped Mada gently in its palm and raised her up so that she could see its screens straight on.

"Nominal, Mada. Everything is as it should be."

That couldn"t be right. She could breathe ship-nominal atmosphere. "Check it again," she said.

"Mada, I"m sorry," said the ship.

The ident.i.ty mine had skipped with them and was still d.o.g.g.i.ng her, five infuriating minutes into the past. There was no getting around it, no way to undo their leap into the future. She was trapped two-tenths of a spin upwhen. The knowledge was like a sucking hole in her chest, much worse than any wound the Utopian psychological war machine could have inflicted on her.

"What do we do now?" asked the ship.

Mada wondered what she should say to it. Scan for hostiles? Open a pleasure sim? Cook a nice, hot stew? Orders twisted in her mind, bit their tails and swallowed themselves.

She considered-briefly-telling it to open all the air locks to the vacuum. Would it obey this order?

She thought it probably would, although she would as soon chew her own tongue off as utter such cowardly words. Had not she and her sibling batch voted to carry the revolution into all ten dimensions?

Pledged themselves to fight for the Three Universal Rights, no matter what the cost the Utopian brain clans extracted from them in blood and anguish?

But that had been two-tenths of a spin ago.

bean thoughts

"Where are you going?" said the ship.

Mada floated through the door bubble of the command mod. She wrapped her toes around the perch outside to steady herself.

"Mada, wait! I need a mission, a course, some line of inquiry."

She launched down the companionway.

"I"m a Dependent Intelligence, Mada." Its speaker buzzed with self-righteousness. "I have the right to proper and timely guidance."

The ship flowed a veil across her trajectory; as she approached, it went taut. That was DI thinking: the ship was sure that it could just bounce her back into its world. Mada flicked her claws and slashed at it, shredding holes half a meter long.

"And I have the right to be an individual," she said. "Leave me alone."

She caught another perch and pivoted off it toward the greenhouse blister. She grabbed the perch by the door bubble and paused to flow new alveoli into her lungs to make up for the oxygen-depleted, carbon-dioxide-enriched air mix in the greenhouse. The bubble shivered as she popped through it and she breathed deeply. The smells of life helped ground her whenever operation of the ship overwhelmed her. It was always so needy and there was only one of her.

It would have been different if they had been designed to go out in teams. She would have had her sibling Thiras at her side; together they might have been strong enough to withstand the Utopian"s panic ...

no! Mada shook him out of her head. Thiras was gone; they were all gone. There was no sense inlooking for comfort, downwhen or up. All she had was the moment, the tick of the relentless present, filled now with the moist, bittersweet breath of the dirt, the sticky savor of running sap, the bloom of perfume on the flowers. As she drifted through the greenhouse, leaves brushed her skin like caresses.

She settled at the potting bench, opened a bin and picked out a single bean seed.

Mada cupped it between her two hands and blew on it, letting her body"s warmth coax the seed out of dormancy. She tried to merge her mind with its blissful unconsciousness. Cotyledons stirred and began to absorb nutrients from the endosperm. A bean cared nothing about proclaiming the Three Universal Rights: the right of all independent sentients to remain individual, the right to manipulate their physical structures and the right to access the timelines. Mada slowed her metabolism to the steady and deliberate rhythm of the bean-what Utopian could do that? They held that individuality bred chaos, that function alone must determine form and that undoing the past was sacrilege. Being Utopians, they could hardly destroy Trueborn and its handful of colonies. Instead they had tried to put the Rights under quarantine.

Mada stimulated the sweat glands in the palms of her hands. The moisture wicking across her skin called to the embryonic root in the bean seed. The tip pushed against the seed coat. Mada"s sibling batch on Trueborn had pushed hard against the Utopian blockade, to bring the Rights to the rest of the galaxy.

Only a handful had made it to open s.p.a.ce. The brain clans had hunted them down and brought most of them back in disgrace to Trueborn. But not Mada. No, not wily Mada, Mada the fearless, Mada whose heart now beat but once a minute.

The bean embryo swelled and its root cracked the seed coat. It curled into her hand, branching and rebranching like the timelines. The roots tickled her.

Mada manipulated the chemistry of her sweat by forcing her sweat ducts to reabsorb most of the sodium and chlorine. She parted her hands slightly and raised them up to the grow lights. The cotyledons emerged and chloroplasts oriented themselves to the light. Mada was thinking only bean thoughts as her cupped hands filled with roots and the first true leaves unfolded. More leaves budded from the nodes of her stem, her petioles arched and twisted to the light, the light. It was only the light-violet-blue and orange-red-that mattered, the incredible shower of photons that excited her chlorophyll, pa.s.sing electrons down carrier molecules to form adenosine diphosphate and nicotinamide adenine dinucleo.

"Mada," said the ship. "The order to leave you alone is now superseded by primary programming."

"What?" The word caught in her throat like a bone.

"You entered the greenhouse forty days ago.""

Without quite realizing what she was doing, Mada clenched her hands, crushing the young plant.

"I am directed to keep you from harm, Mada," said the ship. "It"s time to eat."

She glanced down at the dead thing in her hands. "Yes, all right." She dropped it onto the potting bench. "I"ve got something to clean up first but I"ll be there in a minute." She wiped the corner of her eye.

"Meanwhile, calculate a course for home."

natural background

Not until the ship scanned the quarantine zone at the edge of the Trueborn system did Mada begin to worry. In her time the zone had swarmed with the battle asteroids of the brain clans. Now the Utopians were gone. Of course, that was to be expected after all this time. But as the ship reentered the home system, dumping excess velocity into the empty dimensions, Mada felt a chill that had nothing to do with the temperature in the command mod.

Trueborn orbited a spectral type G3V star, which had been known to the discoverers as HR3538.

Scans showed that the Green Sea had become a climax forest of deciduous hardwood. There were indeed new mountains-knife edges slicing through evergreen sheets-that had upthrust some eighty kilometers off the Fire Coast, leaving Port Henoch landlocked. A rain forest choked the plain where the city of Blair"s Landing had once sprawled.

The ship scanned life in abundance. The seas teemed and flocks of Trueborn"s flyers darkened the skies like storm clouds: kippies and bluewings and warblers and migrating stilts. Animals had retaken all three continents, lowland and upland, marsh and tundra. Mada could see the dust kicked up by the herdsof herbivorous aram from low orbit. The forest echoed with the clatter of shindies and the shriek of blowhards. Big hunters like kar and divil padded across the plains. There were new species as well, mostly invertebrates but also a number of lizards and something like a great, mossy rat that built mounds five meters tall.

None of the introduced species had survived: dogs or turkeys or llamas. The ship could find no cities, towns, buildings-not even ruins. There were neither tubeways nor roads, only the occasional animal track. The ship looked across the entire electromagnetic spectrum and saw nothing but the natural background.

There was n.o.body home on Trueborn. And as far as they could tell, there never had been.

"Speculate," said Mada.

"I can"t," said the ship. "There isn"t enough data."

"There"s your data." Mada could hear the anger in her voice. "Trueborn, as it would have been had we never even existed."

"Two-tenths of a spin is a long time, Mada."

She shook her head. "They ripped out the foundations, even picked up the dumps. There"s nothing, nothing of us left." Mada was gripping the command perch so hard that the knuckles of her toes were white. "Hypothesis," she said, "the Utopians got tired of our troublemaking and wiped us out. Speculate."

"Possible, but that"s contrary to their core beliefs." Most DIs had terrible imaginations. They couldn"t tell jokes, but then they couldn"t commit crimes, either.

"Hypothesis: they deported the entire population, scattered us to prison colonies. Speculate."

"Possible, but a logistical nightmare. The Utopians prize the elegant solution."

She swiped the image of her home planet off the screen, as if to erase its unnerving impossibility.

"Hypothesis: there are no Utopians anymore because the revolution succeeded. Speculate."

"Possible, but then where did everyone go? And why did they return the planet to its pristine state?"

She snorted in disgust. "What if," she tapped a finger to her forehead, "maybe we don"t exist. What if we"ve skipped to another timeline? One in which the discovery of Trueborn never happened? Maybe there has been no Utopian Empire in this timeline, no Great Expansion, no s.p.a.ce Age, maybe no human civilization at all."

"One does not just skip to another timeline at random." The ship sounded huffy at the suggestion. "I"ve monitored all our dimensional reinsertions quite carefully, and I can a.s.sure you that all these events occurred in the timeline we currently occupy."

"You"re saying there"s no chance?"

"If you want to write a story, why bother asking my opinion?"

Mada"s laugh was brittle. "All right then. We need more data." For the first time since she had been stranded upwhen, she felt a tickle stir the dead weight she was carrying inside her. "Let"s start with the nearest Utopian system."

chasing shadows

The HR683 system was abandoned and all signs of human habitation had been obliterated. Mada could not be certain that everything had been restored to its pre-Expansion state because the ship"s database on Utopian resources was spotty. HR4523 was similarly deserted. HR509, also known as Tau Ceti, was only 11.9 light years from earth and had been the first outpost of the Great Expansion.

Its planetary system was also devoid of intelligent life and human artifacts-with one striking exception.

Nuevo LA was spread along the sh.o.r.es of the Sterling Sea like a half-eaten picnic lunch. Something had bitten the roofs off its buildings and chewed its walls. Metal skeletons rotted on its docks, transports were melting into brown and gold stains. Once-proud boulevards crumbled in the orange light; the only traffic was windblown litter chasing shadows.

Mada was happy to survey the ruin from low orbit. A closer inspection would have spooked her.

"Was it war?" "There may have been a war," said the ship, "but that"s not what caused this. I think it"s deliberate deconstruction." In extreme magnification, the screen showed a concrete wall pockmarked with tiny holes, from which dust puffed intermittently. "The composition of that dust is limestone, sand, and aluminum silicate. The buildings are crawling with nan.o.bots and they"re eating the concrete."

"How long has this been going on?"

"At a guess, a hundred years, but that could be off by an order of magnitude."

"Who did this?" said Mada. "Why? Speculate."
