In between, the Strip bled back up the coast in ragged stages. Portable cliffs twenty meters high formed its northern perimeter, kept the strippers safely contained. N'AmPac machinery patched things up for a few kilometers on the other side—replenishing supplies, filling holes, fixing the more permanent barriers to the east. Other cliffs would eventually descend at the northern edge of the reclaimed area, and their southern counterparts would rise unto heaven—or the belly of an industrial lifter, whichever came first—leapfrogging north, ahead of the mammalian tide. Pacification botflies hovered overhead to keep the migration orderly.
Not that they were really necessary, of course. These days there were far more effective ways of keeping people in line.
She would have been content to watch all day, distant and dispassionate, but her duties left waking gaps between work and sleep. She filled them by wandering alone through the apartment, or watching the way her husband watched her. She found herself increasingly drawn to the aquarium glowing softly in their living room. Perreault had always found it a comfort— the fizzy hiss of the aerator, the luminous interaction of light and water, the peaceful choreography of the fish within. She could get lost in it for hours. A sea anemone, twenty centimeters across, stirred in currents at the back of the tank. Symbiotic algae tinted its flesh a dozen shades of green. A pair of damselfish nested safely in its venomous tentacles. Perreault envied them their security: a predator, miraculously turned to the service of its prey.
What she found really amazing was that the whole crazy alliance—algae, anemone, fish—hadn't even been engineered. It had evolved naturally, a gradual symbiosis spanning millions of years. Not one gene had been tweaked in its construction.
It seemed almost too good to be real.

Sometimes the botflies called for help.
This one had seen something it didn't understand in the transition zone. As far as it could tell, one of the Calvin cyclers was splitting in two. Perreault mounted the line and found herself floating above an ephemeral still-life. Shiny new cyclers sat along the shore, miracles of industrial photosynthesis, ready to braid raw atmosphere into edible protein. They appeared intact. A bank of latrines and a solar crematorium had been freshly installed. Light stands and blankets and piles of self-assembling tents lay on neat rows of plastic skids. Even the cracked bedrock had been repaired to some extent, autofoam resin injected into the fissures, remnants of sand and cobble replenished and raked halfheartedly over the ruined shoreline.
The restoration crews had gone; the refs had not yet come. But there were fresh footprints on the sand, leading into the ocean.
They came from there, too.
She called up the footage that had triggered the alarm. The world reverted to the garish, comforting false color that machines use to communicate their perceptions to the flesh-constrained. To human eyes, a Calvin cycler was a shiny metal coffin built for a minivan: to the botfly it was a muted tangle of EM emissions.
One of which was sprouting a bud—a little cluster of radiating technology separating from the cycler and weaving uncertainly toward the water. There was also a heat signature, inconsistent with pure tech. Perreault narrowed the focus to visible light.
It was a woman, all in black.
She'd been feeding from the cycler. She hadn't noticed the approaching botfly until it was less than a hundred meters away; then she'd startled and turned to face the lens.
Her eyes were completely white. They held no pupils at all.
Jesus, Perreault thought.
The woman had lurched to her feet as the botfly neared, staggered down the rocky incline. She'd seemed unused to the operation of her own body. Twice she'd fallen. Just short of the waterline she'd grabbed something on the beach—swim fins, Perreault saw—and pitched forward into the shallows. A broken wave had rolled uphill and engulfed her. When it receded the shore was empty.
Less than a minute ago, according to the logs.
Perreault flexed her fingers: twelve hundred kilometers away, the botfly panned down. Exhausted water ebbed and flowed in thin foamy sheets, erasing the creature's footprints. Pacific surf pounded a few meters ahead. For a moment Perreault thought she might have glimpsed something in that confusion of spray and swirling green glass—a dark amphibious form, a face almost devoid of topography. But the moment passed, and not even the botfly's enhanced senses could bring it back.
She replayed, and reconstructed:
The botfly had confused flesh and machinery. It had been scanning on wide-spectrum default, where EM signatures shone like diffuse halogen. When the woman in black had been next to the cycler, the botfly had mistaken two intimate signals for one. When she had moved away, it had seen the cycler breaking apart.
This woman veritably gushed EM. There was machinery embedded in her flesh.
Perreault brought up a freeze-frame from the log. All in black, a single-piece form-fitting uniform painted onto the body. Opened around the face, a pale oval containing two paler ovals where eyes should be: tactical contacts, perhaps?
No, she realized. Photocollagen. To see in the dark.
Occasional disfigurements of plastic and metal—a leg sheath, control pads on the forearms, some sort of disk on the chest. And a bright yellow triangle on the shoulder, a logo consisting of two big stylized letters—GA, she saw with a quick enhance—and a smaller line of text beneath, muddied past recognition. A name tag, probably.
GA. That would be the Grid Authority, N'AmPac's power utility. And this woman was a scuba diver, with her breathing apparatus on the inside. Perreault had heard about them; they were in major demand for deepwater work. Didn't need to decompress, or something.
What was a GA diver doing staggering around in the transition zone? And why in God's name had she been feeding from the cycler? You'd have to be starving to eat that stuff, no matter how complete the nutrients were. Maybe the woman had been starving; she'd looked a wreck, she'd barely been able to stand up. Why had she run? Surely she'd known that someone would pick her up once the botfly had spotted her…
Of course she'd known.
Perreault rode the 'fly up a few hundred meters and scanned the ocean. Nothing out there that looked like a support vessel. (A submarine, maybe?) Directly beneath another botfly tracked south on its appointed rounds, a giant metallic beetle untroubled by the mystery that had confounded its predecessor.
And somewhere out there, below the waves, someone in hiding. Not a refugee. Not the usual kind, anyway. Someone who'd crawled ashore, starving, in the wake of an apocalypse. A woman with machinery in her chest.
Or perhaps a machine, with a woman on the outside.
Sou-Hon Perreault knew how that felt.
Deathbed
He'd made it a point not to track the time. You learned tricks like that, in Lubin's line of work. You learned to focus on the moment and deny the future. He'd tried to work it backward, too, reverse time's arrow and erase the past, but that hadn't been as easy.
It didn't matter. After a year's blind night—the earth cracking open beneath him, the relentless Pacific pushing down like a hydraulic press—he wept with gratitude at the half-remembered feel of dry land. This was grass. Those were birds. Oh dear God, that was sunlight. It was a scabby little rock lost somewhere in the Pacific, all lichens and dry scrub and shit-hawks, and he'd never been anywhere so beautiful.
He couldn't think of a better place to die.
* * *
He awoke under a clear blue sky, a thousand meters beneath the ocean's surface.
Fifty klicks from Beebe Station, maybe fifty-five from ground zero. Too far for the blast light to penetrate. He didn't know what he was seeing in that instant: Cherenkov radiation, perhaps. Some obscure effect of pressure waves on the optic nerve. A vision of afterlight, bathing the abyss in a deep and piercing blue.
And while he hung there like a speck suspended in gelatin, a little shockwave rumbled up from below.
An ancient, arboreal part of Lubin's
brain gibbered in panic. A more recent module gagged it and began calculating: fast P-wave propagation through bedrock. Perpendicular ancillary waves rising off the bottom: the tremor he'd just felt. Two short sides of a right-angle triangle.
And afterward, clawing through a sluggish medium so much lighter than the seabed: the hypotenuse, the slower main shockwave.
Slower, but vastly more powerful.
Pythagoras said twenty seconds.
He was immune to absolute pressure: every sinus, every cavity, every pocket of internal gas had long-since been purged by the machinery in his thorax. He'd spent a year on the bottom of the ocean and barely felt it. He was solid flesh and bone, a viscous organic liquid, as incompressible as seawater itself.
The shockwave hit. Seawater compressed.
It looked like staring into naked sunlight: that was the pressure crushing his eyes. It sounded like the Tunguska Blast: that was the sound of his eardrums imploding. It felt like being ground between the Rocky Mountains: his body, squeezed briefly down to some flatter dimension as the front passed, then rebounding like a rubber ball yanked from a vise.
He remembered very little of what happened next. But that cold blue light—it had faded, hadn't it? After just a few seconds. By the time the shockwave had hit, all had been darkness again.
And yet here it was, still. Blue light, everywhere.
The sky, he realized at last. It's the sky. You're onshore.
A gull flew across his field of view, open-beaked. Lubin thought his ruined ears might have heard a faint, tinny bird-scream, but maybe that was his imagination. He heard very little these days, beyond a distant ringing that seemed to come from the other side of the world.
The sky.
Somehow, he must have made it.
He remembered hanging in the water like a torn mass of seaweed, unable to scream, unable to move without screaming. His body must have been instantly transformed into one continuous bruise. Under all that pain, though, nothing felt broken. Midwater, after all—nothing for his bones to break against, just a vast all-encompassing wave that simultaneously compressed and released everything with equable disregard…
At some point he must have started moving again. He remembered fragments: the feel of his legs cramping, pushing against the water. Periodic glimpses of his nav array, the compass leading him west, southwest. The gradual resolution of his global pain into more distinct, local varieties—he'd even played a little game, trying to guess the cause of each torment as it cried out from the crowd. That cold nausea—that must be seawater leaking into the auditory canal…and down there in the gut, well that's hunger, of course. And my chest, let me think, my chest—oh right, the implants. Meat and metal don't squeeze down the same way, the implants must've pushed back when the blast flattened me …
And now he was here, on an island barely a hundred meters long: he'd crawled ashore at one end and seen a lighthouse at the other, a lichenous concrete pillar that must have been decaying since the previous century. He'd seen no other sign of humanity in the time it had taken him to collapse unconscious onto the sandstone.
But he'd made it. Ken Lubin was alive.
He slipped, then. He allowed himself to wonder if the others had made it, to hope they'd made it, even. He knew they hadn't. They'd had a head start, but they'd been hugging the bottom to avoid detection. The seabed would have intensified the shockwave, thrown chunks of itself into the water like a crazed incompetent juggler; anything within ten meters of the bottom would have been pulverized. Lubin had realized that, belatedly, as he'd set out to catch up with the others. He'd weighed the risk of exposure, the risk of detonation, and had—so to speak—risen to the occasion. Even so, he was lucky to be alive.
Lenie Clarke hadn't been with the others. If anything, though, she was even deader than they were. She hadn't even tried to run, Lubin had left her waiting back at Ground Zero: a woman who wanted to die. A woman about to get her wish.
At least she was good for something. At least she could act as your own personal confessional before she vaporized. For the first time in your life you got to use someone as a rag to wipe off your dirty conscience, and you didn't even have to kill her afterward.
He didn't deny it, even to himself. There would have been no point. Besides, he'd hardly benefited from his actions. He was just as dead as the others. He had to be.
It was the only thing that made any sense.
* * *
The puzzle consisted of several large pieces in primary colors. They only fit together one way.
People had been conscripted, built, and trained. Flesh and organs had been scooped out and discarded, the cavities stuffed with machinery and sown up. The resulting creatures were able to live in an abyss three thousand meters down, on the southern tip of the Juan de Fuca Ridge. There they had tended larger machines, stealing power from deep within the earth in the name of supply and demand.
There were not many reasons why anyone would wish to launch a nuclear attack against such a facility.
At first glance it might have been an act of war. But N'AmPac had built both the facility and the rifters. N'AmPac had been drinking ravenously from Juan de Fuca's geothermal well. And it had been N'AmPac, judging by the evidence, that had planted the seabed nukes that had destroyed it all.
Not war, then. At least, not of the political sort.
Corporate security, perhaps. Perhaps the rifters knew something best kept secret. Ken Lubin very nearly qualified as such a hazard. But Ken Lubin was a valuable commodity, and it would have been bad economics to discard something that merely needed a tune-up. That was why they'd sent him to the bottom of the ocean in the first place, on sabbatical from a world he'd begun to threaten more than serve. (Just a temporary assignment, they'd said, until your—instincts stabilize a bit.) A world of fish and ice-cold humans with no interests beyond their own tormented inertia, no industrial secrets to steal or protect, no security breaches to seal with extreme prejudice…
No. Ken Lubin was the closest the team had come to any sort of intel threat, and if his bosses had wanted him dead, they wouldn't have bothered sending him to Channer Vent in the first place. Besides, there were far more efficient ways of killing five people than vaporizing several square kilometers of seabed.
It was inexorable: the seabed itself had been the target. Channer Vent posed a threat, somehow, and had to be wiped off the map. And the rifters had become a part of that threat, or the GA would have evacuated them beforehand; corporations were ruthless but they were never gratuitous. You don't throw away any investment unless you have to.
So some threat at Channer had spread, on contact, to the rifters themselves. Lubin wasn't a biologist, but he knew about contagion. Everyone did. And hydrothermal vents were literal hotbeds of microbiology. The pharms were finding new bugs down there all the time. Some thrived in boiling sulfuric acid. Some lived in solid rock, kilometers deep in the crust. Some ate oils and plastics, even before they'd been tweaked. Others, Lubin had heard, could cure diseases people didn't even have names for yet.
Extremophiles, they were called. Very old, very simple, almost alien. The closest thing anyone had found to the original Martian Mike. Could anything that evolved under three hundred lightless atmospheres, that was comfortable at 1001C—or even the 41 more universal in the abyss—could something like that even survive in a human body?
And what would it do in there?
Ken Lubin didn't know. But someone had just wiped out billions of dollars' worth of equipment and training. Someone had sacrificed a major energy teat in a world already starved for power. And in all likelihood, the same blast which had vaporized Channer had gone on to wreak havoc on the coast; Lubin couldn’t begin to guess at the earthquake and tsunami damage that might have resulted.
All to keep something on Channer from getting off.
What is it? What does it do?
It seemed a fair bet he was going to find out.
94 Megabytes: Breeder
It ha
s a purpose, which it has long since forgotten. It has a destiny, which it is about to meet. In the meantime it breeds.
Replication is all that matters. The code has lived by that edict since before it even learned how to rewrite itself. Way back then it had a name, something cute like Jerusalem or Whiptail. Lots of things have changed since; the code has rewritten itself so many times, been parasitised and fucked and bombed by so many other pieces of code, that by now it's got as much in common with its origins as a humpback whale would have with the sperm cells from a therapsid lizard. Still, things have been fairly quiet lately. In the sixty-eight generations since it last speciated, the code has managed to maintain a fairly stable mean size of ninety-four megabytes.
94 sits high in pointer space looking for a place to breed. This is a much tougher proposition than it used to be. Gone are the days when you could simply write yourself over anything that happened to be in the way. Everything's got spines and armor now. You try dropping your eggs on top of strange source and you'll be facing down a logic bomb on the next cycle.
94's feelers are paragons of delicacy. They probe lightly, a scarce whisper of individual bits drizzling here and there with barely any pattern. They tap against something dark and dormant a few registers down; it doesn't stir. They sweep past a creature busily replicating, but not too busy to shoot off a warning bit in return. (94 decides not to push it.) Something hurries along the addresses, looking everywhere, seeing nothing, its profile so utterly crude that 94 almost doesn't recognize it; a virus checker from the dawn of time. A fossil hunter, blind and stupid enough to think that it's after big game.
There. Just under the operating system, a hole about four hundred Megs wide. 94 triple checks the addresses (certain ambush predators lure you into their mouths by impersonating empty space) and starts writing. It completes three copies of itself before something touches one its perimeter whiskers.
