The herd was bigger now.
Ren Vasquez lay flat on a ridgeline above Route 18, rifle beside her, map spread across the pine needles, and watched the dark mass move through the valley below.
Two weeks ago it had been a smudge on the horizon, a smear of motion, too far to count and too big to ignore.
Now it was a river.
A slow patient river of dead things flowing across the northwest lowlands, feeding on whatever it crossed — a fallen camp, a dead farm, a stretch of road where a convoy had tried to run and failed — and growing with every mile.
She’d counted maybe two hundred the first time, from the drainage ditch.
Now she was looking at four hundred.
Maybe five.
And it was still swelling.
It’s heading south.
Slow, but south.
If it holds its bearing it crosses the Holdfast in three weeks.
Maybe two.
Less if it picks up speed.
She marked the bearing with a stub of charcoal, a dark line running southeast, crossing Route 18 at the overpass, passing within a mile of the gas station.
“Two weeks,” she said to the pine needles.
“You’ve got two weeks and an hour of wall.”
Because that was the arithmetic.
Herds didn’t run straight; they drifted, pulled by noise and fire and whatever residue of habit was left in them.
But the bearing was close enough, and everything Marcus had built out of barricade and razor wire and car husks and chain-link would slow four hundred bodies for about an hour before it went under them.
She’d volunteered for this loop three days ago, standing in the forecourt with her pack already on.
“Two days,” she’d told him.
“Maybe three. I want the north lowlands and the ridge above the overpass.”
“That’s a long way to walk to look at nothing.”
“It’s a long way to walk to find out it’s nothing.”
He’d given her the flat look he saved for a wall he couldn’t read.
“What do you think is out there?”
“If I could answer that I wouldn’t need to go.”
“Take the good canteen.”
“I’m taking both.”
The cold was getting worse.
Two days out on jerky and creek water, sleeping in the lee of fallen trees, moving at dawn and dusk when the dead were slowest.
Her boots were finally dry.
Her hands were cracked from the wind, and the cut on her palm, a scrape off the culvert grate the day she found Micah, had reopened and was stinging in a way that meant infection if she didn’t clean it.
Clean the cut.
Find water.
Keep moving.
The ridge gave her a view Marcus would never have.
His Holding Sense stopped at the wire.
Beyond it the world went dark to him.
He could feel a threat at the gate, a pressure on a wall, a walker at two hundred yards, and he could not feel this, could not see a river of dead things bending toward the thing he’d built, because the System only read the ground he’d claimed, and the ground he’d claimed was going to be underneath four hundred walkers.
He’s down there siting walls and counting diesel and telling himself Cutter’s the problem.
The problem’s the size of a county and it’s walking.
The rival crew found her at midday.
Not Cutter’s.
She knew Cutter’s men by now, the clean hands and the maintained boots, the arrogance of a crew that had been winning since the collapse.
These three were leaner.
Scavenged clothes, bad teeth, the patience of men who’d learned patience was the only weapon they could afford.
They’d cut her tracks in the pine needles, because she’d been careless, moving fast, thinking about the herd instead of her own trail.
She heard them before she saw them.
A boot on gravel.
A voice pitched too low to carry.
The particular silence of people trying to be quiet.
She was already moving, rolling off the ridge into a drainage gully with her map folded and her rifle slung, heart hammering, hands steady.
Three men.
Hungry.
They want stores, not a fight.
Stay still and they pass.
Run and they chase.
She didn’t run.
She pressed into the cold mud of the gully and lay still, rifle ready, breathing slow and shallow.
They passed twenty yards above her, close enough that she could smell them, sour bodies and old smoke, and their voices came down the slope like ash.
“Tracks were fresh. She’s close.”
“You keep saying close.”
“Heel’s still got an edge on it. That’s this morning.”
“So we walk the ridge till dark chasing a girl with one rifle and no pack worth taking.” A pause, and the wet sound of somebody spitting.
“You want her, be my guest. I want the camp she’s working out of. There’s a station down the road, block’s been Claimed, you can see the wall from the crossing. They’ve got fuel. They’ve got tools. That’s worth more than one scout.”
“You know whose block that is.”
“Cutter’s. Or it was. Word is he tried to tax them and they told him no.”
“They told Cutter no.”
“That’s the word.” A laugh with nothing warm in it.
“Bold. Stupid, but bold.”
“Bold people leave good gear behind.”
“That’s the whole idea.”
Their voices thinned.
Boots on gravel, going east.
Ren lay in the gully until her heartbeat came down and the mud’s cold had worked through her jacket and the only sound left was wind in the pines.
They know about the Holdfast.
They know Cutter tried and failed.
If these three know it, everybody on this road knows it.
The Banner’s a beacon, and beacons pull both kinds.
Then the fork, and she’d known it was coming since she left the wire.
The herd lay northwest and her brother’s trail lay northeast, and she had water for one of them.
Three days ago Micah had come to the gate to watch her go.
He hadn’t held her sleeve.
He’d stood a foot away with his hands at his sides, doing the thing he did instead of speaking, which was to look at her until she answered a question nobody had asked.
“Four days at the outside,” she’d said.
“You count them on your fingers. When you run out of fingers on one hand, I’m late, and you can be annoyed with me.”
Nothing.
“He wants to know if you’re coming back,” Cass had said from the ladder.
“That’s what that face is.”
“I know what the face is.”
“So?”
“I’m coming back,” Ren had said, and she’d hated how easy it was to say, because she hadn’t known if it was true and she’d said it anyway.
Micah’s down there.
Cass.
Hollis.
Dell.
Even the goat.
None of them know what’s walking at them, and I’m the only one who’s seen it.
She turned northwest.
It cost her.
The brother-trail went cold, maybe a week, maybe for good, maybe until the herd had passed and the roads cleared and she could work northeast again with a full canteen.
The marker at the culvert stayed unconfirmed, the same open wound it had been since the first night.
Walls over blood.
A warning over a search.
I’m choosing them.
I’m choosing the walls I swore I’d never need, and I’ll have to keep choosing them, every time the road calls, until it stops calling or I stop answering.
She crested the ridge at dusk and marked the bearing one last time.
The river was still flowing, still growing, still bending toward the block where a silent boy was counting days on one hand.
“All right,” she told the map, and folded it, and put it in the pocket over her heart where the note about Micah was, and started down the south face of the ridge at a jog she could hold for an hour.
