Subject Zero

The first thing I remember is the cold.

The second is Ember's laugh, echoing through the vents.

I press my forehead to the window, watching the world I've never touched. Outside, sunlight glints off the security fence, and beyond that, the city shimmers—so close I can almost taste its freedom. My hands tingle with energy, the kind that could stitch flesh or restart a heart, but here, in Helix Institute's glass room, I'm nothing but a specimen.

On the wall, the TV flickers. Ember's on the news again, flames dancing at her fingertips, eyes wild with purpose. She looks older, braver, than the girl who used to sneak into my cell with stolen candy and whispered stories of the sky.

"Don't you ever wish you could go out there?" she once asked, her face pressed against the glass.

I did. I do. But Dr. Voss says I'm too dangerous. That the world isn't ready for someone who can undo death.

The news anchor's voice sharpens. "Breaking: Ember faces Obsidian atop the city's North Bridge. Officials urge citizens to evacuate—"

I clutch the window ledge, knuckles white. Ember's silhouette blazes against the night, but Obsidian is a shadow that swallows light. The fight is brutal. Ember falls. The screen goes black.

My scream is silent. The guards rush in, syringes ready, but I'm already planning.

Tonight, I'm breaking out.

Tonight, I'm bringing her back.

The silence after the blackout is suffocating. My breath fogs the glass, and for a moment, I can't tell if the trembling in my hands is fear or the electric pulse of my power, begging to be used. I press my palm flat against the window, wishing I could send my heartbeat out to her—some signal, some spark of hope.

Footsteps thunder in the corridor. The guards' voices are clipped, urgent. I catch fragments through the door—"containment," "protocol," "subject unstable." They're talking about Ember, but soon they'll turn their attention to me. They always do.

I remember the first time Ember showed me how to pick the lock on my ankle cuff. "It's just metal," she'd whispered, her grin daring me to try. "You're more than what they built you to be." I never managed it, but tonight, the memory feels like a promise.

The door hisses open. I don't flinch as the guards enter, their faces hidden behind mirrored visors. I know their routine: restrain, sedate, report. But tonight, I meet their gaze—my reflection staring back, eyes burning with something new.

Hope. Or maybe defiance.

As the needle bites my skin, I focus on Ember's laugh echoing through the vents, on the city lights beyond the fence, on the power thrumming in my veins. The sedative is cold, but I hold onto the warmth of memory.

Tonight, I won't just dream of escape.

Tonight, I'll make it real.

The world softens at the edges, colors bleeding into one another as the sedative seeps through me. I fight to stay awake, teeth clenched, willing my mind to hold onto every detail—the hum of the lights, the chill from the vent, the distant wail of sirens outside the Institute walls.

The guards' voices fade, replaced by the low, familiar rattle of Ember's laughter in my memory. I see her crouched beside my bed, flame dancing on her palm, lighting up the shadows. "You're not a prisoner, Nova," she'd said, her eyes fierce. "You're a storm waiting to break."

I cling to that. To her. To the plan forming in the back of my mind.

I know the Institute's routines as well as my own heartbeat. In three hours, the night shift will change. The security feed will loop for exactly forty seconds—long enough for someone with the right clearance to slip through the halls. Long enough for me, if I can break the restraints, if I can harness what they fear most about me.

My eyelids flutter, heavy with the drug, but I force them open. I picture Ember's fall, the way the fire vanished from her hands. I picture what I can do—what I must do.

If I can reach her in time, maybe I can undo what's been done. Maybe I can prove Dr. Voss wrong. Maybe I can be more than just the girl in the glass room.

The last thing I hear before sleep drags me under is my own voice, barely a whisper:

"Wait for me, Ember. I'm coming."

Darkness presses in, thick and muffling. For a moment, I'm weightless—adrift between memory and dream. I see Ember's face, smudged with soot and grinning, her eyes reflecting firelight. I see the city beyond the fence, neon and alive, calling me home.

A distant clang jolts me. The sound echoes through the vents, sharper than the haze in my mind. I force my fingers to curl, to feel the rough sheet beneath me. I will not disappear into the drug. I will not let them win.

Somewhere outside my room, alarms begin to pulse—a low, warning thrum. The Institute is on edge. Maybe it's Ember's battle on the bridge, maybe it's the fear that I'll do what they've always dreaded: break free.

I focus on the rhythm of the alarms, syncing my breath to their pulse. My power stirs, a faint current beneath my skin. I picture the lock on my ankle cuff, the way Ember showed me, the way she believed I could do anything.

I'm not just a test subject. I'm not just a girl in a glass room.

I am the storm Ember saw in me.

The sedative pulls harder, but I hold on to one thought, bright and unyielding:

Tonight, I will not wait for rescue.

Tonight, I will rescue myself—and her.

The world narrows to the steady beep of my heart monitor and the distant, metallic wail of alarms. I force my eyes open, blinking away the blur. The guards are gone, but the restraints remain—a cold band around my ankle, the IV taped to my arm. I flex my fingers, feeling the familiar hum of energy coil in my chest.

I remember Ember's hands guiding mine, her voice low and urgent: "It's not about strength, Nova. It's about focus. Find the current. Let it flow."

I close my eyes, searching for that current now. My heartbeat slows, the sedative tugging at my thoughts, but I push past it. I picture the circuitry in the cuff, the tiny spark it would take to overload it. My fingertips tingle.

A soft crackle. The scent of ozone. The cuff heats beneath my skin, then pops open with a hiss. I stifle a gasp, heart pounding with something dangerously close to hope.

I swing my legs over the side of the bed, the room spinning. The IV tugs at my arm, but I grit my teeth and pull it free, blood beading at the puncture. The pain is sharp, grounding.

For the first time, the glass room feels small—not a cage, but a starting line.

I press my palm to the door's sensor. The mechanism inside whirs, uncertain, then clicks open. The hallway beyond is empty, washed in red emergency light.

I step into the corridor, Ember's promise echoing in my mind:

"You're more than what they made you."

Tonight, I believe her.

The corridor stretches ahead, bathed in the pulsing red of emergency lights. Shadows flicker, distorting the familiar path into something strange and dangerous. My bare feet are silent on the cold tile, every step measured, every breath deliberate.

I keep close to the wall, listening for the telltale stomp of boots or the crackle of radios. For now, there is only the distant blare of alarms and the hum of electricity in the walls—a current I can almost taste.

I pass the observation room, its glass wall spiderwebbed with cracks. Inside, monitors flicker between static and looping footage. I catch a glimpse of myself on the screen—pale, determined, eyes burning with something I barely recognize.

I am not the girl who waited for permission. Not tonight.

A door slams somewhere above me. Voices echo, sharp with panic. "She's loose." "Find her." "Lockdown, now." They don't say my name, but I feel it in every syllable, a warning and a challenge.

I slip down a side hall, heart racing. The map Ember drew for me weeks ago is etched in my mind—left at the junction, past the labs, down the service stairs. If I can make it to the lower levels, I can reach the old maintenance tunnels. From there, freedom.

But first, I have to find Ember.

I pause at the next intersection, pressing my hand to the wall, letting my power reach out—searching for the familiar spark that is hers. For a moment, there is nothing. Then, faint and flickering, I feel it: a thread of heat, a promise.

I follow.

The thread of heat leads me deeper into the Institute, past locked doors and silent laboratories. My footsteps are quick but careful, every sense straining for danger. I can feel Ember—her signature, wild and bright—somewhere ahead, pulsing like a beacon through the static of fear and adrenaline.

A pair of guards rounds the corner, flashlights slicing through the gloom. I press myself into a shadowed alcove, barely daring to breathe. Their voices are tense, clipped.

"She can't have gotten far."

"Orders are to bring her in—no mistakes this time."

I close my eyes, willing my power to settle, to cloak me in invisibility. Not literal—yet—but enough to make me small, to slip past unnoticed. The guards move on, boots thudding, radios crackling with frantic updates.

As soon as their voices fade, I dart forward, following the map in my mind. Left at the emergency exit, down a narrow flight of stairs, past a storage room where broken equipment gathers dust. The air grows warmer, tinged with the faint scent of smoke.

My pulse quickens. Ember is close.

I find her in a holding cell, slumped against the wall, wrists bound with reinforced cuffs. Her hair is tangled, face bruised, but her eyes snap open the moment I enter. Relief and fire flare in her gaze.

"Nova," she breathes, voice raw but unbroken. "You made it."

I kneel beside her, hands already working at the cuffs. "I told you I would."

For the first time in days, hope feels real—alive between us, burning brighter than any alarm.

Ember's hands tremble as I rub at the angry red marks left by the cuffs. She grins through the pain, her eyes shining with relief and resolve.

"We have to move," I whisper, glancing at the flickering lights above us. "They'll be here any second."

Ember nods, pushing herself upright. She's weaker than I remember, but the fire in her is undimmed. "You remember the way?"

I nod, picturing the map in my mind. "Maintenance tunnels. We can reach them through the old records room—if we're fast."

A crash echoes from somewhere up the corridor. Shouts follow, boots pounding closer. Ember grabs my hand, her grip tight. "Let's go."

We slip into the hallway, moving as one. The Institute feels different now—less like a labyrinth, more like a gauntlet. Every shadow could hide a threat; every corner, a chance at freedom or capture.

We reach the records room. I scan the keypad, willing the ancient circuitry to respond. It sputters, then clicks open. We duck inside, closing the door behind us just as footsteps thunder past.

For a moment, we're safe. Ember leans against the shelves, catching her breath. "You did it," she says, voice soft with awe.

But I shake my head. "Not yet. We're not out. Not until we're free."

Together, we search for the hatch that will lead us below, hope and fear warring in my chest. The night is far from over—but for the first time, we're facing it together.

The records room is cramped, filled with dusty cabinets and stacks of yellowed files. The air is thick with the scent of paper and something older—memories, maybe, or secrets waiting to be uncovered.

Ember moves with me between the shelves, her steps growing steadier. "It should be here," I murmur, scanning the floor for the outline of the hatch Ember described so many nights ago, when escape was just a dream.

A thud sounds against the door. I freeze, heart hammering. Voices bark orders on the other side, muffled but urgent.

"Hurry," Ember urges, her voice barely a whisper.

My fingers find a seam in the linoleum, almost invisible. I drop to my knees, prying at the edge. The hatch resists, stuck from years of disuse, but Ember kneels beside me, adding her strength to mine. Together, we wrench it open with a groan that seems impossibly loud.

Below, darkness yawns. The maintenance tunnel smells of rust and damp earth. Ember looks at me, fear and hope mingling in her eyes.

"Ready?" I ask, voice shaking.

She nods. "With you? Always."

The door rattles, hinges straining. Without another word, we lower ourselves into the darkness, pulling the hatch closed just as the door bursts open above.

For a moment, we are suspended in silence, hearts pounding, breaths mingling in the cold, subterranean air. Then, with a shared look, we begin to crawl forward—into the unknown, together.

The tunnel is narrow and pitch-black, the only sound our ragged breathing and the distant chaos above. I lead the way, one hand trailing along the damp wall, the other gripping Ember's fingers. The air is heavy, thick with the promise of freedom and the fear of what waits ahead.

Behind us, voices echo through the hatch—frustrated, searching. I force myself to keep moving, even as my knees scrape against the rough floor and my muscles scream in protest.

Suddenly, the tunnel widens into a small chamber. Faint light trickles down from a grate overhead, painting Ember's face in silver and shadow. She looks at me, determination burning in her eyes.

"We're almost there," she whispers, and I want to believe her.

A clang reverberates down the tunnel. The guards have found the hatch. Panic claws at my chest.

"We have to go faster," I say, voice trembling.

Ember nods, but just as we start forward, a low rumble shakes the ground. Dust rains from the ceiling. Somewhere above, alarms wail louder, overlapping with the shouts of our pursuers.

I spot a ladder leading up to the grate. "There!" I hiss, pointing. Ember scrambles up first, hands slipping on the cold metal. I follow, heart pounding, every second stretching out like an eternity.

She pushes at the grate. It doesn't budge. The rumbling grows louder—closer. I climb up beside her, bracing my shoulder against the metal. Together, we shove with everything we have.

With a screech, the grate gives way, swinging open to the night sky above. Cool air rushes in, filling my lungs with hope.

Ember hauls herself onto the surface, then reaches down for me. Our hands clasp, and for a heartbeat, the world narrows to that single, desperate connection.

Just as I pull myself free, a spotlight sweeps across the rooftop, pinning us in its harsh glare.

"Stop! Don't move!"

We freeze, side by side, backs to the edge of the roof. The city sprawls below, a maze of lights and shadows. The Institute's guards are closing in, their shouts echoing through the night.

Ember squeezes my hand, her voice fierce and steady in my ear. "We're not going back. Not now. Not ever."

And as we leap into the darkness—toward the unknown, toward freedom—I know this is only the beginning.
