Chapter 8: Pressure Break

The corridor was breathing. Not air pressure. Each pulse in the walls matched the thud in my chest. Somewhere below us, the pumps were dying, choking on their own weight.

Max took point like he owned the ground, which meant he was leading us into another trap. Evelyn stayed close enough to put a bullet through his spine if he twitched wrong. The mirror woman trailed just behind me, her hand brushing my jacket every time the lights flickered.

Water streaked the walls, cold enough to sting. The hum of the tanks was fainter here, but not gone. Nothing in this place was ever gone.

The floor sloped upward, but the water was catching us anyway, chasing like it had teeth.

Max stopped at a rusted steel door. “Through here.”

Evelyn didn’t wait for him to elaborate. “Open it.”

He spun the wheel, slow, savoring the squeal of metal. “Patience. This next part’s delicate.”

I kept my blade ready. “Delicate’s not your thing.”

He grinned. “You’d be surprised.”

The door swung inward, and the smell hit first mildew over brine, thick enough to taste. The room beyond was circular, walls lined with control panels older than my childhood nightmares. Gauges twitched like they were nervous. A wide window faced a tank so big it could swallow the last three rooms we’d crossed combined.

Something moved in the tank’s depths. Not the shadow. Bigger.

Max walked straight to the central console, running his fingers over switches like a pianist deciding where to start. “This is where we find out if you’ve got a future.”

I stayed at the threshold. “My future doesn’t come from your machines.”

“Oh, it’s not for you,” he said without looking up. “It’s for her.”

He meant my sister. I didn’t ask how. Asking would be giving him ground.

Evelyn’s voice cut in. “Talk.”

Max flicked a switch, and the panels came alive dim, sputtering, but alive. On one monitor, grainy video showed my sister in another chamber. The water was ankle-high there too. She was standing on a crate, arms wrapped around herself, eyes locked on something off-screen.

“She’s fine for now,” Max said. “But there’s a pressure breach two levels down. This whole place is one chain reaction away from turning into an aquarium.”

The mirror woman stepped closer to the screen. Her voice was small. “That’s her?”

“Yes,” I said, sharper than I meant to.

The lights flickered. A metallic groan echoed through the floor. Max’s fingers danced across the controls. “You want her out, you’ve got two choices shut the breach and buy time, or take the express route to her chamber before the thing below catches up.”

The thing below. The shadow in the pipes. My skin prickled.

Evelyn glanced at me. “If we split, we lose leverage over him.”

Max smiled like he’d been waiting for her to say that. “Smart girl.”

The tank behind the glass stirred again. This time I saw it something pale rising, slow as a dream you can’t wake from. Long dorsal spines, each tipped with something like bone hooks. It pressed against the glass, testing.

The mirror woman whispered, “What is that?”

Max answered without looking. “Insurance.”

The glass flexed under the thing’s weight. A hairline crack bloomed across the surface.

“Tell me that’s normal,” I said.

“Nothing here’s normal,” Max replied.

The crack widened with a sound like ice breaking on a lake. Evelyn raised her gun at the glass. “If that goes, we’re all dead.”

Max waved her off. “Not if we move fast.”

The panel in front of him beeped a shrill, steady tone. On the monitor, my sister flinched at something off-screen. Then the feed went black.

I was moving before I thought. “Where is she?”

Max blocked my path. “Choose.”

I didn’t hesitate. I slammed him against the console, blade at his ribs. “Wrong answer.”

He laughed, breathless. “You still think you’re not playing my game. That’s adorable.”

The glass behind us groaned again. Water seeped through the crack in a slow, steady stream.

Evelyn’s voice was tight. “We’re out of time.”

The mirror woman grabbed my arm. “If we go now, we can still reach her.”

Max’s smirk faltered for the first time. Not much, but enough. “Fine. Follow me. And don’t fall behind.”

We ran. The corridor beyond was narrower, the air sharp with rust. Water rushed past our boots, climbing faster than before. Somewhere in the pipes above, metal clanged a rhythm, steady, getting closer.

The thing below wasn’t below anymore.

We hit a junction. Max took the left path without hesitation. Evelyn kept her gun on him the whole way, even while running. I heard the mirror woman’s breath catching behind me.

A slam shook the wall to our right. Something massive scraped along the other side. The sound followed us, matching our speed.

“Faster,” Max said.

We burst into another chamber this one with two heavy doors, each with a wheel lock. Max went to the left door. I went to the right.

“Yours is a dead end,” he called over.

“Yours leads to her?” I asked.

“Yes.”

“Then open it.”

He spun the wheel. The door creaked inward and there she was. My sister. Soaked, shaking, but alive. She looked at me like I was both a ghost and a promise.

I barely had time to step inside before the sound hit metal tearing, water exploding into the chamber behind us. The thing had arrived.

Its shadow stretched long across the walls, limbs unfolding like a nightmare unrolling itself.

Max shoved us forward. “Move!”

We ran again me, Evelyn, my sister, the mirror woman, Max. The corridor ahead was climbing, but the water was faster.

Behind us, the thing’s limbs scraped the walls, sparks spraying where claw met steel.

We hit another hatch. Max spun it open, and daylight pale, cold spilled through.

We weren’t safe. Not yet. But for the first time, the air didn’t smell like rot.

I didn’t look back.
