Chapter 25: The Ribs Close

The tunnel bled light. Not sunlight. Something rawer, stranger. Each pulse crawled along the ribs like veins lit under skin, throbbing a faint blue that made the walls breathe. Shadows bent the wrong way, twisting toward us instead of away. Evelyn’s knife caught the glow and shimmered like ice instead of steel.

My throat still burned with the hymn. Every swallow was glass dragged raw. My fingers came back wet and red when I touched my neck. The sound wasn’t gone. It crouched inside, coiled, patient, waiting for another chance to split me open.

The ground flexed under our boots. Not stone. Cartilage. Springy, soft, with a give that made each step feel like walking inside a lung.

“Keep moving,” Evelyn said.

Her hand brushed my back. Not gentle. Just pressure, keeping me upright. Always forward. Always control. My sister clung to her other hand, her wrist bare where the bracelet used to be. The chain had snapped earlier, but she carried the broken piece like treasure, fingers clenched around it until her knuckles went white. The charms clinked with each step, tiny bells mocking the silence.

Behind us, the chamber sealed. Teeth snapping shut. The sound wasn’t just heard it tore through my ribs, clamping down on my lungs until I wheezed. A verdict, final and cruel.

The tunnel narrowed, ribs tightening. My shoulders scraped the sides. Flesh brushed my cheek, slick, damp. The taste of copper flooded my tongue and I gagged. Evelyn hacked at the sinew ahead, knife sawing through, carving space.

Water seeped through every crack. Black, oily, slow at first, but rising. Always rising.

“How much further?” I rasped. My voice came out wrong too deep, too layered. Like another voice riding mine.

Evelyn didn’t turn. “Until it ends.”

“That’s not an answer.”

“It’s the only one.”

She was right. This place wasn’t built for exits.

The tunnel tilted downward. My boots skidded, cartilage slick beneath me. I pitched forward. Evelyn’s grip clamped my collar and yanked me upright, nearly choking me. Her strength was all steel.

“You fall here, you don’t get up,” she said.

“I’m already down.” My laugh rattled, broken.

Her eyes cut sharp. “Not yet.”

The hymn stirred at the sound of my laugh. Eager. Hungry. It scraped against my ribs, pressing upward, begging for release.

I bit my tongue, copper bursting. The taste anchored me.

The tunnel widened without warning. We stumbled into a cavern shaped like an inverted ribcage. Walls curved high, ribs fused into jagged spires. Veins pulsed faint blue, twitching like strings being plucked by invisible fingers.

At the center was a pool. Still. Too still. Black surface stretched flat as glass.

My sister whimpered. Evelyn shoved her behind, knife angled high.

I knew what lived in that pool before it moved.

The shadow rose slow. Long, boneless arms dripping. A head without features, stretched hollow. No eyes, but it stared all the same.

The hymn in me surged, clawing. It wanted to join. To harmonize.

My chest convulsed. A note slipped free, low, guttural. The pool rippled, answering.

Evelyn’s knife pressed cold against my side. Not deep. Just enough to remind me of the line. “Control it.”

“You think I’m” My throat broke mid-word, the note slicing higher. My knees buckled.

She shoved me against the wall, blade steady. “Control it or I end it here.”

My sister screamed. “Don’t! Please!”

The shadow stretched taller, swaying, arms dragging ripples. The pool hissed, boiling at the edges.

I pressed both hands to my throat, useless. The hymn wasn’t leaving. It was swelling.

“I can’t”

“You can,” Evelyn snapped. Her face was stone. “Or you’ll drown us all.”

The hymn pressed harder. My ribs rattled, lungs convulsing. The note tore free, sharp, piercing. The cavern vibrated. Dust rained down, soft as ash.

The shadow leaned in, drinking it.

My sister’s charms rattled, a desperate noise. That small clink sliced through the hymn for a breath. A cut. A memory.

I seized it. Dug my nails into my palm until skin broke. Pain grounded me. I twisted the note. Not harmony. Discord.

The hymn cracked. My scream tore raw, jagged.

The pool detonated. Water lashed outward, flaying cartilage from walls. The shadow convulsed, folding, collapsing in on itself like burning paper.

My body followed, ribs searing, throat shredding open.

Then silence.

True silence.

The pool lay empty.

I dropped to my knees, shaking. Evelyn hovered, knife still in her hand, never lowering. My sister collapsed against me, arms tight, tears burning down her face.

“You stopped it,” she whispered.

No. I hadn’t. The hymn still crouched inside, quieter now, but alive.

Evelyn crouched close, forehead almost brushing mine. Her knife gleamed between us. Her voice was a blade. “You’ll burn before this ends. But you’ll take it with you.”

I laughed, hoarse, bitter. “That’s your comfort speech?”

“No. That’s survival.”

The cavern trembled. Ribs cracked overhead. Water surged through splits, rushing in fast. Rising.

Evelyn yanked us up. “Move.”

We slogged through water climbing our legs. The ribs groaned, closing behind us.

The pool wasn’t empty anymore. Shadows twitched at the bottom, waiting to rise.

We ran.

The tunnel ahead sloped upward. A glow pulsed faint at the end. Not sunlight. Something worse. But it was the only way.

Behind me, the hymn hummed. Low. Patient.

This wasn’t escape.

This was rehearsal.

The real song hadn’t started yet.

And I was the throat it would use.
