Kathree’s eye went to a detail she had noticed a minute ago: an unnatural-looking deposit of flat black rocks half buried in wave-driven sand. As the remainder of the party made their final descent to the water’s edge, she used a piece of driftwood to scrape sand and gravel away from these until she could worry one loose. Though it was rough around the edges, it had clearly been shaped by humans: a slab of black rock about as thick as her finger, big enough to hold in the crook of an arm, smooth enough to write on. Scattered in the muck around it she’d seen lumps of calcium carbonate: chalk. Traces of it were still visible on the slates. Not writing but a fragment of a diagram, a map perhaps, and a few numbers.

PROJECTING FROM ONE SIDE OF THE ISLET, JUST BELOW THE TOP OF it, was a snarl of driftwood: the stump of a tree that a storm had torn from the edge of a cliff somewhere along the coast and later hurled up here. As soon as he arrived, Ty dropped his pack, emptied his pockets, and picked up the boxy equipment case that Roskos Yur had delivered in his glider. Holding this up above his head to keep it dry, he waded out to the islet, cursing at the intensity of the cold. At its deepest, the water came up to his waist, with occasional waves clipping him under the chin. He tossed the case up onto the flank of the islet and then clambered up after it.

After gazing curiously at the stump for some moments, he squatted down, gripped it by a couple of protruding roots, and overturned it, causing it to tumble into the surf. He then edged back out of the others’ sight line to reveal what had been hidden beneath it: a vertical section of stout steel pipe, about a hand’s breadth in diameter, rising to the height of a person’s knee, topped with a flat disk of battered steel the size of a dinner plate. The pipe wasn’t rooted to the boulder itself. It was part of a longer object that extended out into the sea. The part above the waterline was lashed to spikes that had been driven into crevices in the rock, in a style that they had already learned to recognize as typical Digger improvisation.

Ty’s attention strayed to something he had noticed at his feet. He bent down and heaved it up so that all on the beach could see it: a sledgehammer improvised from a length of pipe and a chunk of steel. Then he looked at the Cyc. Looking back at Ty she held her hands out, palms toward the gray sky, as if to say: See? Just like I said.

Ty turned away from them, gazing down into the sea before the boulder. After a few moments he turned back around. “How far does it extend?” he shouted.

“The pipe? A few score yards,” answered the Cyc. “The crater is as a horn, channeling the sound out into the deep.”

She had scarcely finished the sentence before Ty hauled off with the sledgehammer and brought it down with all his might on the steel plate. The result was a blindingly loud metallic ping, drowned out, as it faded, by a scream from Kathree, who sank to her knees in the sand with her hands clamped over her head.

“Better get her out of here,” Ty said — she could hear him through her hands. She felt Beled reaching around her from behind, crooking her in one arm below her breasts, heaving her to her feet. Which was welcome on one level. But she was tired of being the one who had to be carried, and so she unwound herself from him, turned her back on the sea, and marched up toward the belt of scrub that marked the limit of the beach. Ty gave her a respectable head start before shouting, “Plug your ears.” She did so, and a moment later felt another ping go through her like an icicle jammed into the base of her skull. A moment later came another and another, not in a steady rhythm, but sporadic. And by the time she had climbed up to a place where she could look down over the cove, fingers in her ears, and not suffer pain from each stroke of the hammer, she had made sense of what Ty was doing.

Each of the human races had its own set of cultural traditions that it traced back to its respective Eve. These were propagated from one generation to the next by social rituals, school curricula, and youth groups. Young Teklans learned zero-gravity gymnastics with a martial arts flair, competing on obstacle courses that reproduced specific maneuvers that Tekla had performed during the Epic. Julians competed on debate teams and went on lengthy retreats intended to symbolize their Eve’s exile and ordeal in the Swarm. And so on.

Young Dinans learned Morse code. It was used very rarely.

Moirans most certainly didn’t learn it, and so Kathree had no idea what message Tyuratam Lake was banging out into the deep.

Everyone, of course, had watched the scene in the Epic, at the beginning of the Hard Rain, where Eve Dinah had made her final transmission to Rufus. This had trailed off with many repetitions of the code QRT, which — especially after Dinah had dissolved in sobs, and slowed her transmission speed to a crawl — had a kind of solemn fanfare-like rhythm to it, beginning with pahm, pahm, pa-pahm. The letter Q. Kathree recognized that pattern, at least, more frequently than you would expect in normal English sentences. So, Ty was using ancient Q codes to shorten his message. But she hadn’t a clue what he was actually saying. He belted it out over and over again, a syncopated phrase of long and short strokes that started to get under her skin after a while. He stopped when Sonar Taxlaw waded out to the rock and assured him that, if the Pingers were about, they would surely have heard the message by now.

“How long now?” he asked. He was shouting over the rush of the surf and because he had probably gone deaf.

“Depends on how far away they are,” said Sonar Taxlaw. “Maybe a day. Maybe three.”

“Great,” Ty said, and looked up to catch the eye of Roskos Yur, who, following a timeless military instinct, pushed his sleeve back to check his timepiece.

Ty unlatched the lid of the box and began to take out pieces of equipment and to peruse instructional brochures. Kathree was too far away to see the details, and in any case it was getting dark. As the sky faded, she could see Ty sitting on the shore of the islet, facing out toward the sea, occasionally flicking on a small light and fussing with equipment. Perched next to him, swaddled in sleeping bags that Einstein had brought out to her, was the Cyc. She wore a bulky pair of headphones, occasionally turning her head toward Ty in an alert birdlike way to make some sort of comment. Esa Arjun paced slowly back and forth on the beach, just out of the waves’ reach, passing occasionally near Einstein, who just stood there gazing fretfully at his beloved. Hope had gone to ground in a small tent pitched a few meters higher up, on drier sand; a bluish flicker through its walls suggested he was working with a tablet, maybe trying to learn something about POTESH management.

So much for the lower camp where Hope, Ty, Einstein, Sonar Taxlaw, and Arjun had made themselves at home. Beled had followed Kathree uphill. Langobard and Roskos Yur later followed him. Spreading out, bushwhacking in all directions, they identified a curved brow in the slope: the line of demarcation between the crater’s inland edge and the preexisting landscape from which it had been blasted. Above it, the slope was much gentler. Indeed, the first thing one saw upon cresting the rim was a slight drop in altitude. Before them, as they stood with their backs to the sea and their faces to the mountains, was a bog a few hundred meters in extent, with a pine forest rising up on its far side. They backpedaled a few paces and set to work establishing an upper camp just below the summit of the rim. Few words were spoken, but it was obvious that its purpose was to defend the beach if and when Red forces approached. If the foe came straight down out of the mountains, they would have to cross the bog. If they came along the beach, they would have to scale or circumvent a prong of the crater’s rim. Either way, they would be clearly visible from this vantage point.

It could be guessed that an ONAN had struck the ground somewhere nearby, several decades ago. Seed-packed siwis had slithered out of it, roaming about, mapping elevations and soil moisture, comparing notes over a mesh network. The collective had noticed the break in the slope leading down to the sea. Following a program drilled into it by some coder up on the ring, it had decided that the coastline might be stabilized here by planting some seeds that would grow up into tough, low, scrubby vegetation. And so it had all come to pass. Siwis that happened to wander away from the beach had found the flat ground beyond the rim and planted it with different species that would thrive in a wet environment. The vegetation had created a bit of a natural dam, holding back water coming down out of the mountains above them. One day it might be a lake, but for now it was a black bog, squishy and knee-deep and screened with grasses and reeds that favored that sort of ground.

Kath Two had not been a fighter. Her weapons training had given her the bare minimum of skill needed to discharge a katapult in the direction of a hungry canid. Kathree didn’t know, yet, whether that was one of the things that had shifted. In a sense it did not matter. No matter how good she might turn out to be at combat, she would never be as effective as Beled, Bard, and — judging from appearances — Roskos Yur. She was, however, finding them to be a dull, slow bunch. They failed to notice much that was obvious to her. And it was clear that they were tired and fading toward sleep. After it had gotten fully dark, Kathree consumed three consecutive full meals from the rations that Roskos Yur had brought with him, then slipped away and climbed a short distance farther up, to the very top of the rim, from which she could look and listen inland.
