Bloom

Wil McCarthy dares to combine two branches of scientific study--space-travel technology and biotechnology--to create a chilling and very believable future as Bloom pits humankind against an enemy of its own creation, grown rampantly out of control. In the late twenty-first century, man-made, self-replicating organisms called mycora--smaller than the tiniest bacteria--mutated and swept across the globe in a chain reaction so swift and deadly there was no time to act. No time to do anything but flee an Earth destroyed by the very science created to nurture and sustain it. Soon the entire inner solar system was consumed, incorporated into the lethal psychedelic bloom of the Mycosystem. Scant years later, the remnants of humanity cling to the asteroid belt and the inhospitable moons of Jupiter. As the society known as the Immunity ekes out a precarious existence, fighting off the invasion of deadly mycospores while working feverishly to build a starship that will carry them to safety, an ominous discovery alters everything. Mycora are incorporating gene sequences to elude Immunity defenses--perhaps even to thrive in the harsh environment of the outer system. The only way to be sure is to journey into the diseased heart of the Mycosystem, from which no one has ever returned. The starship is readied and a crew is selected on the basis of expertise--and expendability. But when sabotage forces an early launch, suspicions arise among the crew. Someone--or something--doesn't want the mission to succeed. As the starship rockets toward Earth, under relentless attack from without and within, the questions and the terror multiply faster than a contagion. Who--or what--is the true enemy? When is change something to fight--or something to embrace? And how can humanity forge a future for itself in the face of an unstoppable foe seemingly destined to overwhelm the cosmos . . . ? With both deep insight into the human condition and a far-reaching understanding of science, Bloom offers a compelling--and frightening--peek into one of our possible futures.

Wil McCarthy, an engineer for the Lockheed Martin Corporation since 1988, is one of the guys who says "Guidance is go  at rocket launches. He lives in Denver with his family. His writing has appeared in Aboriginal SF, Analog, Interzone, Asimov's, Science Fiction Age, and a veritable plethora of short fiction anthologies. Bloom is his fifth novel.

ZERO: Sometimes They Get In

This much we know: that the Innensburg bloom began with a single spore;
that Immune response was sluggish and ineffective; that the first witness
on the scene, one Holger Sanchez Mach, broke the nearest emergency glass,
dropped two magnums and a witch's tit, and died. Did he suffer? Did it
hurt? Conversion must have taken at least four seconds, and we can
probably assume it started with the feet. These things usually do.

By the time the Response teams began arriving, the bloom was some ten
meters across, and two meters high at the center--a fractal-jagged bubble
of rainbow fog, class two threaded structure almost certainly visible to
those unfortunate enough to be standing within fecund radius when the
fruiting bodies swelled and popped. Twenty deaths followed almost
immediately, and another hundred in the minutes that followed.

There were cameras and instruments on the scene by this time, windows on
what can only seem to be separate events, each holograph showing a
different fleeing mob or collapsing building, each soundtrack recording a
different cacophony of whimpers and death screams and jarringly irrelevant
conversation. I personally have collaged these scenes a dozen times or
more, arranging the panic this way and that way, over and over again in
the hope that some sense will emerge. But there is no sense in those first
few minutes, just the pettiness and blind, stamping fear of the human
animal stripped bare. And the heroism, yes; for me the central image is
that of Enrico Giselle, Tech Two, pushing his smudged helmet and visor
back on his forehead and shouting into a voice phone while the walls
behind him froth and shimmer and disintegrate.

"Class five! Class five! Drop two hundred and flush on my command!"
At this point, finally, the city began to awaken. The Immunity isolated
samples of the invading mycorum, sequenced them, added them to the catalog
of known pathogens. Better late than never, one supposes, but by this time
the bloom outmassed the city's Immune system by a factor of several
million, and though submicroscopic phages gathered at its sizzling
interface, now ropy with tendrils that sputtered outward in Escheresque
whorls, the growth was not visibly affected.

Fortunately, like all living things, technogenic organisms require energy
to survive, and where the witch's tits had fallen or been hurled, pools of
bitter cold had arrested the replication process. Not unusual, as any
Response officer will tell you. And like organic lebenforms, mycora are
also vulnerable to excess energy. Backpack UV lasers were proving
effective weapons against the bloom, and soon the streets clanged with
discarded chem spritzers and paraphage guns as bloomfighters concentrated
on the things that worked.

High above the city, the cavern roof came alive with UV turrets of its
own. Machine-guided and wary of the soft humans below, the beams swept
back and forth, charring trenches through the rainbow mist, the living
dust, the bloom of submicroscopic mycora still eating everything in their
reach and converting it to more of themselves. And to other things, as
well, a trillion microscopic construction projects all running in
parallel, following whatever meaningless program the mycogene codes called
out. By now the fecund zone was half a kilometer across, riddled with gaps
and voids in the outer regions but much denser at its core, a thickening
haze that already blocked the view from one side to the other. Up to four
stories tall in places, higher than most of the surrounding buildings, and
it had begun to take on structure as well--picks and urchins, mostly,
standing out visibly in the haze, their prismatic spines lengthening more
than fast enough for the human eye to see.

Some mycora eat lightly, sucking up building blocks like carbon and
hydrogen while leaving the heavier elements alone, but this one was
pulling the gold right off the streets, the steel right off the shingled
walls, the zirconium right out of the windowpanes. You've seen the
pictures: a giant bite out of Innensburg's south side, gingerbread houses
dissolving like a dream.

The UV lasers, while no doubt satisfying for those employing them, were if
anything adding to the problem by throwing waste heat into the bloom,
giving it that much more energy to work with, to feed on.

Finally, Innensburg's central processor sought permission from the mayor
and city council to move to Final Alert. Permission was granted, the
overhead lights and household power grid were shut off, the ladderdown
reactors stopped, and the air system reconfigured to pipe through cooling
radiators closer to the surface. The cold, the dark. How we humans hate
these things, and how very much we need them!

Like all Jupiter's moons, like all the moons of the outer system,
Ganymede's surface is cold enough to liquefy both oxygen and nitrogen, and
while the spore-fouled air was not cooled quite that far, Innensburg's
ground temperature quickly dropped below the freezing point of water, and
then below that of carbon dioxide. A seconds-brief rain fell and froze.
Mycoric replication slowed to a crawl. A sigh of mingled fear and relief
went up all over the city, visible as columns of white steam in the
flashlight beams of the Response. The emergency far from over, but now
survivable, now something that could be dealt with in a reasoned,
methodical manner.

Some thirty-one deaths were later attributed to the cold, to the darkness,
to the lack of domestic power and computing, and while some of the
families did attempt to bring suit against the authorities responsible,
public and judicial outrage squashed the move before it had gotten very
far. One hundred and eighty-seven deaths preceded the chilldown, after
all, and most of Innensburg's fifty thousand residents came out of it with
only minor injuries.

Throughout the Immunity, our problems are the same: so far from the places
of our birth, so far from the sun's warm rays, so far from the lives we
once expected to lead. Eaten by the Mycosystem, those lives, and billions
of others as well. And yet out here in the cold and dark we hang on, even
thrive, because we're brave enough to believe we can. If the space around
us is lousy with mycoric spores blown upward by solar wind, well, at least
we can do what's necessary to keep them outside.

I think the Honorable Klaus Pensbruck, in closing the book on Glazer v.
Cholm, speaks for us all with his immortal words, "Shut up, lady. We don't
want to end up like the Earth."

ONE

Destination Where?

That my first meeting with Vaclav Lottick went poorly goes without saying.
The most powerful man in the solar system, yes, you can believe he had
better things to do than exchange small talk with me. And yet, certain
business can be conducted in no other way.

He looked up and smiled when his secretary, a quiet, efficient man,
ushered me inside the office. Everything beige and cream and shiny, not
quite sterile in appearance but compact, and clean. Very clean. The
windows' light was from behind Lottick, highlighting every stray hair, and
the desk lamp seemed designed to show off the lines in his face. A pale
man, nearly bald, his rumpled smock no longer white. Even his zee-spec was
an older model, blocky, folding his ears back, weighing on the bridge of
his nose, leaving his features to sag that much more.

"John Strasheim, hi," he said, rising from his chair and extending a hand.
"Thanks for coming on such short notice."

Shaking his hand, I shrugged. "Happy to help, I guess. What can I--"

"Take a seat, then. Set to receive a flash?"

"Sure."

His thick fingers danced in the space between us. My receiving light went
on, and the air before me came alive with information, image windows and
text windows and schematic windows rastering in and then shrinking to
icons as my spec compressed them in working memory. It was too quick to
see much in the way of detail. Pictures of blooms, I thought. Pictures of
mycora. Well, what else would one expect from the Immunity's head of
research?

I sat.

"I've seen your work," he said to me, his voice vaguely approving. "And
read it. Funny, how nobody seems to be doing that sort of thing anymore."

"You're talking about Innensburg?"

He nodded. Behind the zee-spec, his eyes were bright green. "Yes,
Innensburg. I survey your net channels from time to time, but it was that
piece that really caught my eye. About as close as we have to a regional
history, and plaintext was a...curiously appropriate choice of medium.
Very astute. I stayed up all night reading it."

"Thank you," I said, nodding once to accept the compliment. Then I smiled
politely, waiting. Whatever he'd invited me here to discuss, this wasn't
it.

He studied me for a moment, then relaxed, turning off the charm like a
lamp he no longer needed. "All right, then."

His fingers stroked the air, manipulating symbols and menus I couldn't
see. One of my image icons began to flicker. I touched and expanded it,
moved the resulting window to the lower right corner of my vision. It was
a video loop, false-color, depicting a complex mycorum which replicated
itself in slow motion, over and over again. Not quite crablike, not quite
urchinlike, not quite organic in appearance. A tiny machine, like a
digger/constructor but smaller than the smallest bacterium, putting copies
of itself together with cool precision, building them up out of nothing,
out of pieces too small for the micrograph to capture. In short, a pretty
typical piece of technogenic life. At the bottom of the window scrolled a
horizontal code ribbon showing, in a series of brightly colored blocks,
what was presumably the data gene sequence which dictated both the
mycorum's structure and behavior.

"This," Lottick said, "is Io Sengen 3a, a sulphurated mycorum with unknown
environmental tolerance. Gave us a scare a while back when we thought it
could replicate in the volcanic flows on Io, but that turned out to be a
false alarm. Now we're concerned again, for different reasons."

"Okay." I nodded, waiting for more, not yet sure why he was telling me
this.

"You know that mycora mutate quickly, right? Everyone knows that. A key
strength, a key factor. The whole Mycosystem probably depends on this, or
it would have died out long ago."

"So I've heard."

"Yes, well, what you probably haven't heard is that they're stealing data
gene sequences from our own phages. Nothing major, nothing all that
important, but the mechanism and its potential limitations are not known
at this time."

"Stealing gene sequences?" I repeated stupidly. My skin had gone cold and
crawly. Mycora were not intelligent, not even alive, really. How could
they steal?

"It's probably nothing," Lottick said. "Statistically, the chance that
they'll steal something important and actually be able to use it to their
advantage is...well, it's zero, basically. But we don't understand the
mechanism, and that has a lot of people upset. Including me. What if the
Mycosystem gets hold of some of our environmental adaptations? What
happens if they stumble on nuclear fission, or cascade fusion, or, God
help us all, they manage to copy some of our ladderdown designs?"

"I don't know," I said, still cold. "What?"

He shrugged. "They eat the solar system, I guess. They eat the universe.
It's not going to happen, Strasheim, but that's the worst-case scenario
we've got to work to. Hence the mission."

"The starship?" I asked, puzzled but optimistic. Whatever the problem was,
these people seemed to be on top of it. Sort of.

"The starship, yeah, right." He chuckled, sounding tired. "We get it
built, we fuel it up, we go on our merry way, every single person who
wants to. That's not going to happen either. I know it's the party line,
and maybe that's best for the time being, but the real goal of the program
is to get our spores out to the neighboring stars before the Mycosystem
beats us to it. Immune system fully established, deny the mycora a toehold
even in the warm, bright spaces. But we've probably got a thousand years
to worry about it, and a lot to keep us busy until then."

"So what are we talking about?"

"The Louis Pasteur," he said. "You may have heard about it here and there;
the program is being accelerated in a big way. Ship is designed for inner-system
operation--high-temperature, high-radiation, also the
t-balance hull--theoretically bloom-proof. But of course, ha ha, we're not
going to test that here on Ganymede. The only way to test it is to fly it
down there, into the Mycosystem, and see if anything eats it. We hope to
do that soon, and if the testing goes well, we'll fly it all the way down
to Earth and Mars and Luna. The thinking goes: even in the inner system,
there are places too cold, dark, barren for mycora to bloom. If any serious
cold-weather
adaptations start appearing, the first signs of it will probably be there.
So we drop a few detectors
on some polar caps, and suddenly we don't have to
worry about this problem anymore. Not unless the detectors start screaming
at us, which I don't think is going to happen."

"Are these state secrets?" I asked, turning to look at his face. "Can I
talk about this stuff?"

His look was disapproving. "There are no secrets, Mr. Strasheim. There's barely any state, and I didn't invite you up here
to waste your time. If we didn't want you to talk about this, what would we
want you for? You have skills
which nobody else in the Immunity seems to possess. You're a commentator,
an historian; you record simple facts in a way that's accessible to the
public, even entertaining. That ability could be very useful for this
project, if you're willing to lend it to us for a while."

"It sounds fascinating," I said sincerely. "I take it you want me to write
an article?"

Lottick looked at me as if I were somewhat stupider than he'd been
expecting. "No, son. I thought we understood each other. I want you to go
on the mission."
