"The last one was on you, so this one's on the house," she told them, and they both laughed. All the time she carefully avoided looking toward Daryn.

Daryn.

He sat at the end of the bar, drinking the beer that the other barmaid had brought him, not gesturing for her to come over, but smugly aware that, sooner or later, she would. He said something that made the other barmaid giggle, and she wondered what it might have been. She served a few of the other sailors, and then, knowing that sooner or later she would, she went to talk to him. "Alive, alive," she said. It was barely more than a whisper.

"Myself, in the flesh," Daryn said. He smiled his huge, goonish smile. "Surprised to see me, yes?"

"How can you be here?" she said. "I thought you were on-on that ship."

" Hesperia? Yeah. But we docked alongside Lictor at Tarrytown-port, and Lictor was short a navigator, and Hesperia could spare me for a bit, and I knew that Lictor was heading to stop here, and I'd have a chance to see you, and-" he spread his hands. "I can't stay."

"You can't stay," she repeated.

"No, I have to sail with Lictor, so I can catch up with Hesperia at Dulcinea." He looked up at her.

She was still standing stupidly there over him. "But I had to see you."

"You had to see me," she repeated slowly, as if trying to understand.

"I had to tell you," he said. "You have to know that you're the only one."

You are such a sweet liar, she thought, how can I trust you? But his smile brought back a thousand memories of time they had spent together, and it was like a sweet ache in her throat. "The only one," she repeated, still completely unable to think of any words of her own to say.

"You aren't still angry, are you?" he said. "Please, tell me you're not still angry. You know that you've always been the only one."

Morning came to the second-shift, and she propped her head up on one elbow to look across the bed at him. The glow of his tattoos cast a mottled pattern of soft light against the walls and ceiling.

Daryn awoke, rolled over, and looked at her. He smiled, a radiant smile, with his eyes still smoky with sleep, and leaned forward to kiss her. "There will be no other," he said. "This time I promise."

She kissed him, her eyes closed, knowing that it would be the last kiss they would ever have.

"I know," she said.

Coelacanths

ROBERT REED.

Robert Reed (info site: www.booksnbytes.com/authors/ reed_robert.html) lives in Nebraska, and has been one of the most prolific short story writers of high quality in the SF field for the past ten years. His work is notable for its variety, and for its steady production. The Encyclopedia of Science Fiction remarks that "the expertness of the writing and its knowing exploitation of current scientific speculations are balanced by an underlying quiet sanity about how to depict and to illumine human beings." His first story collection, The Dragons of Springplace (1999), fine as it is, skims only a bit of the cream from his body of work. And he writes a novel every year or two, as well. His first novel, The Leesh.o.r.e, appeared in 1987, followed by The Hormone Jungle (1988), Black Milk (1989), Down the Bright Way (1991), The Remarkables (1992), Beyond the Veil of Stars (1994), An Exaltation of Larks (1995), and Beneath the Gated Sky (1997). His most recent novel is Marrow (2000), a distant-future large-scale story that is hard SF and seems to be a breakthrough in his career. The New York Times called it "an exhilarating ride, in the hands of an author whose aspiration literally knows no bounds."

"Coelacanths," from F&SF, is a story of the far future in which post-humans occupy most evolutionary niches-too good a concept to pa.s.s up. He published enough stories to fill a first-rate single-author collection in 2002, but none better than this one.

THE SPEAKER.

He stalks the wide stage, a brilliant beam of hot blue light fixed squarely upon him. "We are great! We are glorious!" the man calls out. His voice is pleasantly, effortlessly loud. With a facehandsome to the brink of lovely and a collage of smooth, pa.s.sionate mannerisms, he performs for an audience that sits in the surrounding darkness. Flinging long arms overhead, hands reaching for the distant light, his booming voice proclaims, "We have never been as numerous as we are today. We have never been this happy. And we have never known the prosperity that is ours at this golden moment. This golden now!" Athletic legs carry him across the stage, bare feet slapping against planks of waxed maple. "Our species is thriving," he can declare with a seamless ease.

"By every conceivable measure, we are a magnificent, irresistible tide sweeping across the universe!"

Transfixed by the blue beam, his naked body is shamelessly young, rippling with hard muscles over hard bone. A long fat p.e.n.i.s dangles and dances, accenting every sweeping gesture, every bold word. The living image of a small but potent G.o.d, he surely is a creature worthy of admiration, a soul deserving every esteem and emulation. With a laugh, he promises the darkness, "We have never been so powerful, we humans." Yet in the next breath, with a faintly apologetic smile, he must add, "Yet still, as surely as tomorrow comes, our glories today will seem small and quaint in the future, and what looks golden now will turn to the yellow dust upon which our magnificent children will tread!"

PROCYON.

Study your history. It tells you that travel always brings its share of hazards; that's a basic, impatient law of the universe. Leaving the security and familiarity of home is never easy. But every person needs to make the occasional journey, embracing the risks to improve his station, his worth and self-esteem.

Procyon explains why this day is a good day to wander. She refers to intelligence reports as well as the astrological tables. Then by a dozen means, she maps out their intricate course, describing what she hopes to find and everything that she wants to avoid.

She has twin sons. They were born four months ago, and they are mostly grown now. "Keep alert,"

she tells the man-children, leading them out through a series of reinforced and powerfully camouflaged doorways. "No naps, no distractions," she warns them. Then with a backward glance, she asks again, "What do we want?"

"Whatever we can use," the boys reply in a sloppy chorus.

"Quiet," she warns. Then she nods and shows a caring smile, reminding them, "A lot of things can be used. But their trash is sweetest."

Mother and sons look alike: They are short, strong people with closely cropped hair and white-gray eyes. They wear simple clothes and three fashions of camouflage, plus a stew of mental add-ons and microchine helpers as well as an array of sensors that never blink, watching what human eyes cannot see.

Standing motionless, they vanish into the convoluted, ever-shifting background. But walking makes them into three transient blurs-dancing wisps that are noticeably simpler than the enormous world around them. They can creep ahead only so far before their camouflage falls apart, and then they have to stop, waiting patiently or otherwise, allowing the machinery to find new ways to help make them invisible.

"I'm confused," one son admits. "That thing up ahead-"

"Did you update your perception menu?"

"I thought I did."

Procyon makes no sound. Her diamond-bright glare is enough. She remains rigidly, effortlessly still, allowing her lazy son to finish his preparations. Dense, heavily encoded signals have to be whispered, the local net downloading the most recent topological cues, teaching a three-dimensional creature how to navigate through this shifting, highly intricate environment.

The universe is fat with dimensions.

Procyon knows as much theory as anyone. Yet despite a long life rich with experience, she has to fight to decipher what her eyes and sensors tell her. She doesn't even bother learning the tricks that coax these extra dimensions out of hiding. Let her add-ons guide her. That's all a person can do, slipping in close to one of them. In this place, up is three things and sideways is five others. Why bother counting?

What matters is that when they walk again, the three of them move through the best combination ofdimensions, pa.s.sing into a little bubble of old-fashioned up and down. She knows this place. Rising up beside them is a trusted landmark-a red granite bowl that cradles what looks like a forest of tall sticks, the sticks leaking a warm light that Procyon ignores, stepping again, moving along on her tiptoes.

One son leads the way. He lacks the experience to be first, but in another few weeks, his flesh and sprint-grown brain will force him into the world alone. He needs his practice, and more important, he needs confidence, learning to trust his add-ons and his careful preparations, and his breeding, and his own good luck.

Procyon's other son lingers near the granite bowl. He's the son who didn't update his menu. This is her dreamy child, whom she loves dearly. Of course she adores him. But there's no escaping the fact that he is easily distracted, and that his adult life will be, at its very best, difficult. Study your biology. Since life began, mothers have made hard decisions about their children, and they have made the deadliest decisions with the tiniest of gestures.

Procyon lets her lazy son fall behind.

Her other son takes two careful steps and stops abruptly, standing before what looks like a great black cylinder set on its side. The shape is a fiction: The cylinder is round in one fashion but incomprehensible in many others. Her add-ons and sensors have built this very simple geometry to represent something far more elaborate. This is a standard disposal unit. Various openings appear as a single slot near the rim of the cylinder, just enough room showing for a hand and forearm to reach through, touching whatever garbage waits inside.

Her son's thick body has more grace than any dancer of old, more strength than a platoon of ancient athletes. His IQ is enormous. His reaction times have been enhanced by every available means. His father was a great old soul who survived into his tenth year, which is almost forever. But when the boy drifts sideways, he betrays his inexperience. His sensors attack the cylinder by every means, telling him that it's a low-grade trash receptacle secured by what looks like a standard locking device, AI-managed and obsolete for days, if not weeks. And inside the receptacle is a mangled piece of hardware worth a near-fortune on the open market.

The boy drifts sideways, and he glimmers.

Procyon says, "No," too loudly.

But he feels excited, invulnerable. Grinning over his shoulder now, he winks and lifts one hand with a smooth, blurring motion- Instincts old as blood come bubbling up. Procyon leaps, shoving her son off his feet and saving him.

And in the next horrible instant, she feels herself engulfed, a dry cold hand grabbing her, then stuffing her inside a hole that by any geometry feels nothing but bottomless.

ABLE.

Near the lip of the City, inside the emerald green ring of Park, waits a secret place where the moss and horsetail and tree fern forest plunges into a deep crystalline pool of warm spring water. No public map tells of the pool, and no trail leads the casual walker near it. But the pool is exactly the sort of place that young boys always discover, and it is exactly the kind of treasure that remains unmentioned to parents or any other adult with suspicious or troublesome natures.

Able Quotient likes to believe that he was first to stumble across this tiny corner of Creation. And if he isn't first, at least no one before him has ever truly seen the water's beauty, and n.o.body after him will appreciate the charms of this elegant, timeless place.

Sometimes Able brings others to the pool, but only his best friends and a few boys whom he wants to impress. Not for a long time does he even consider bringing a girl, and then it takes forever to find a worthy candidate, then muster the courage to ask her to join him. Her name is Mish. She's younger than Able by a little ways, but like all girls, she acts older and much wiser than he will ever be. They have been cla.s.smates from the beginning. They live three floors apart in The Tower Of Gracious Good, which makes them close neighbors. Mish is pretty, and her beauty is the sort that will only grow as she becomes a woman. Her face is narrow and serious. Her eyes watch everything. She wears flowing dresses and jeweled sandals, and she goes everywhere with a clouded leopard named Mr. Stuff-and-Nonsense. "Ifmy cat can come along," she says after hearing Able's generous offer. "Are there any birds at this pond of yours?"

Able should be horrified by the question. The life around the pool knows him and has grown to trust him. But he is so enamored by Mish that he blurts out, "Yes, hundreds of birds. Fat, slow birds. Mr.

Stuff can eat himself sick."

"But that wouldn't be right," Mish replies with a disapproving smirk. "I'll lock down his appet.i.te.

And if we see any wounded birds...any animal that's suffering...we can unlock him right away...!"

"Oh, sure," Able replies, almost sick with nerves. "I guess that's fine, too."

People rarely travel any distance. City is thoroughly modern, every apartment supplied by conduits and meshed with every web and channel, shareline and gossip run. But even with most of its citizens happily sitting at home, the streets are jammed with millions of walking bodies. Every seat on the train is filled all the way to the last stop. Able momentarily loses track of Mish when the cabin walls evaporate.

But thankfully, he finds her waiting at Park's edge. She and her little leopard are standing in the narrow shade of a horsetail. She teases him, observing, "You look lost." Then she laughs, perhaps at him, before abruptly changing the subject. With a nod and sweeping gesture, she asks, "Have you noticed? Our towers look like these trees."

To a point, yes. The towers are tall and thin and rounded like the horsetails, and the hanging porches make them appear rough-skinned. But there are obvious and important differences between trees and towers, and if she were a boy, Able would make fun of her now. Fighting his nature, Able forces himself to smile. "Oh, my," he says as he turns, looking back over a shoulder. "They do look like horsetails, don't they?"

Now the three adventurers set off into the forest. Able takes the lead. Walking with boys is a quick business that often turns into a race. But girls are different, particularly when their fat, unhungry cats are dragging along behind them. It takes forever to reach the rim of the world. Then it takes another two forevers to follow the rim to where they can almost see the secret pool. But that's where Mish announces, "I'm tired!" To the world, she says, "I want to stop and eat. I want to rest here."

Able nearly tells her, "No."

Instead he decides to coax her, promising, "It's just a little farther."

But she doesn't seem to hear him, leaping up on the pink polished rim, sitting where the granite is smooth and flat, legs dangling and her bony knees exposed. She opens the little pack that has floated on her back from the beginning, pulling out a hot lunch that she keeps and a cold lunch that she hands to Able. "This is all I could take," she explains, "without my parents asking questions." She is reminding Able that she never quite got permission to make this little journey. "If you don't like the cold lunch," she promises, "then we can trade. I mean, if you really don't."

He says, "I like it fine," without opening the insulated box. Then he looks inside, discovering a single wedge of spiced sap, and it takes all of his poise not to say, "Ugh!"

Mr. Stuff collapses into a puddle of towerlight, instantly falling asleep.

The two children eat quietly and slowly. Mish makes the occasional noise about favorite teachers and mutual friends. She acts serious and ordinary, and disappointment starts gnawing at Able. He isn't old enough to sense that the girl is nervous. He can't imagine that Mish wants to delay the moment when they'll reach the secret pool, or that she sees possibilities waiting there-wicked possibilities that only a wicked boy should be able to foresee.

Finished with her meal, Mish runs her hands along the hem of her dress, and she kicks at the air, and then, hunting for any distraction, she happens to glance over her shoulder.

Where the granite ends, the world ends. Normally nothing of substance can be seen out past the pink stone-nothing but a confused, ever-shifting grayness that extends on forever. Able hasn't bothered to look out there. He is much too busy trying to finish his awful meal, concentrating on his little frustrations and his depraved little daydreams.

"Oh, goodness," the young girl exclaims. "Look at that!"

Able has no expectations. What could possibly be worth the trouble of turning around? But it's an excuse to give up on his lunch, and after setting it aside, he turns slowly, eyes jumping wide open and asurprised grunt leaking out of him as he tumbles off the granite, landing squarely on top of poor Mr.

Stuff.

ESCHER.

She has a clear, persistent memory of flesh, but the flesh isn't hers. Like manners and like knowledge, what a person remembers can be bequeathed by her ancestors. That's what is happening now. Limbs and heads; p.e.n.i.ses and v.a.g.i.n.as. In the midst of some unrelated business, she remembers having feet and the endless need to protect those feet with sandals or boots or ostrich skin or spiked shoes that will lend a person even more height. She remembers wearing clothes that gave color and bulk to what was already bright and enormous. At this particular instant, what she sees is a distant, long-dead relative sitting on a white porcelain bowl, bare feet dangling, his orifices voiding mountains of waste and an ocean of water.

Her oldest ancestors were giants. They were built from skin and muscle, wet air and great slabs of fat. Without question, they were an astonishing excess of matter, vast beyond all reason, yet fueled by slow, inefficient chemical fires.

Nothing about Escher is inefficient. No flesh clings to her. Not a drop of water or one glistening pearl of fat. It's always smart to be built from structure light and tested, efficient instructions. It's best to be tinier than a single cell and as swift as electricity, slipping unseen through places that won't even notice your presence.

Escher is a glimmer, a perfect and enduring whisper of light. Of life. Lovely in her own fashion, yet fierce beyond all measure.

She needs her fierceness.

When cooperation fails, as it always does, a person has to throw her rage at the world and her countless enemies.

But in this place, for this moment, cooperation holds sway.

Manners rule.

Escher is eating. Even as tiny and efficient as she is, she needs an occasional sip of raw power.

Everyone does. And it seems as if half of everyone has gathered around what can only be described as a tiny, delicious wound. She can't count the citizens gathered at the feast. Millions and millions, surely. All those weak glimmers join into a soft glow. Everyone is bathed in a joyous light. It is a boastful, wasteful show, but Escher won't waste her energy with warnings. Better to sip at the wound, absorbing the free current, building up her reserves for the next breeding cycle. It is best to let others make the mistakes for you: Escher believes nothing else quite so fervently.

A pair of sisters float past. The familial resemblance is obvious, and so are the tiny differences.

Mutations as well as tailored changes have created two loud gossips who speak and giggle in a rush of words and raw data, exchanging secrets about the mult.i.tude around them.

Escher ignores their prattle, gulping down the last of what she can possibly hold, and then pausing, considering where she might hide a few nanojoules of extra juice, keeping them safe for some desperate occasion.

Escher begins to hunt for that unlikely hiding place.

And then her sisters abruptly change topics. Gossip turns to trading memories stolen from The World. Most of it is picoweight stuff, useless and boring. An astonishing fraction of His thoughts are ba.n.a.l. Like the giants of old, He can afford to be sloppy. To be a spendthrift. Here is a pointed example of why Escher is happy to be herself. She is smart in her own fashion, and imaginative, and almost everything about her is important, and when a problem confronts her, she can cut through the muddle, seeing the blessing wrapped up snug inside the measurable risks.

Quietly, with a puzzled tone, one sister announces, "The World is alarmed."

"About?" says the other.

"A situation," says the first. "Yes, He is alarmed now. Moral questions are begging for His attention."

"What questions?"
