The smell hits first. Mildew and scorched wiring and the particular dead-air stench of a bandwidth-null zone—the kind of nothing that means the signal repeaters have been down again, three days running, and nobody who matters has filed the maintenance request. Zone 12-Gray smells like a place the algorithm forgot to index.
I'm two blocks from home when I see Mira's window.
She's got the lamp angled. That's the first thing. Not the living-room overhead—that blows yellow and sad and washes out every skin tone within four meters. The lamp. The one we dragged up from the third-floor junk pile eighteen months ago because the shade was intact and the bulb still had half its hours. She's angled it forty-five degrees toward the east wall, which bounces soft and fills the shadow under her chin.
She learned that from somewhere. She learned that deliberately.
I stop moving.
The street is empty at this hour—pre-dawn in 12-Gray is the only time it ever gets close to quiet, that particular suspended silence before the water-ration queue starts and the arguments begin and the day decides what shape it's going to take. My boots have a split in the left sole that lets in the cold in a thin precise line, and I can feel it now, the freezing seeping through, because I have gone completely still on the cracked pavement staring up at my sister's window and understanding, in the specific stomach-dropping way of someone who knows a person too well, exactly what the angled lamp means.
She's streaming.
I start running before the thought finishes.
The building stairs are concrete and the third step from the top has been crumbling since we moved in and I skip it without looking, muscle memory, one hand on the pitted railing. The hallway smells like our neighbor's recycled protein and the mold that lives behind the east wall no matter how many times our mother seals it. Four seconds from the stairs to our door. I don't knock.
She's standing in the corner of the kitchen-slash-living-room we've all pretended is two separate spaces for the three years we've lived here. She's wearing the blue jacket that used to belong to our mother—the one with the fraying cuffs Mira always rolls up twice so they don't cover her hands. In her right hand, steady as anything, she's holding the shared unit. The camera is on. The stream counter in the upper corner of the unit's cracked screen is spinning up: forty-two viewers, sixty-eight, a hundred and one, and climbing fast because Mira has done something I didn't know she knew how to do, which is use the Meridian's open volunteer channel on a direct algorithm hook, and the algorithm is always hungry and it is eating right now and the number is still climbing.
On the floor in front of her, propped against the leg of the chair we use as a table, is a piece of packaging cardboard. She has written on it in the thick black marker we use for labeling storage containers. The letters are large and clear and her handwriting has always been better than mine.
TREATMENT COST: 847,000 CREDITS.
ZONE 12 MEDICAL SUBSIDY: 12,200 CREDITS.
I'M VOLUNTEERING FOR THE MERIDIAN.
IF I WIN, MOM LIVES.
HER NAME IS ELLA VOSS.
The number. I know that number. I have been knowing that number for four months, turning it over in my hands in the dark when I can't sleep, feeling its edges, testing the weight of it against every possible calculation and coming up short every single time. Eight hundred and forty-seven thousand credits. Cytolytic regenerative therapy, the kind that targets the specific mutation in our mother's adenocarcinoma, the kind that works, the kind that is so far outside the Zone 12 subsidy ceiling that the subsidy functions less as help and more as a reminder of exactly how much you are expected to die quietly.
I look at my sister.
She looks at me.
For three full seconds we just stand there—Mira with the unit in her hand and the lamp behind her and the stream counter ticking past four hundred, me in the doorway with the cold still bleeding through my boot sole—and I read her face the way I have been reading her face since she was two years old and I was five and I understood for the first time that she was the person I was most responsible for on this earth.
She's terrified. She has the jaw-set and the chin-up and the particular flatness in her eyes that Mira deploys when she has made a decision she knows is going to hurt and she is determined not to let it show, and it shows anyway, always, because she never quite mastered the part where you stop your hands from tightening. Her left hand, the one not holding the unit, is a fist at her side.
She looks, I realize, with a cold shock that has nothing to do with my boot, like someone who has already said goodbye to something.
"Kael." Her voice is steady. That's the worst part. "Don't."
The stream counter passes eight hundred. The volunteer window is thirty seconds, the Meridian's intake interface is cycling on the unit screen behind the camera, and somewhere in a server cluster in Zone 2-Platinum a piece of automated architecture is reading the open stream and the sign and the follower spike and preparing to lock the slot confirmation in—
"Mira—"
"I've thought about it." She takes one step back, an involuntary one, planting herself. "The math works. I'm young and I test high and the competition odds for a first-year from a poor zone have been improving and I've watched every season back to—"
"You're fourteen."
"The minimum age is fourteen."
There is nothing I can say to that that is not also an argument for why she should get to do this, and she knows it, and I know she knows it, and the stream counter passes twelve hundred.
Later—not now, now there is no time for later—I will think about what it means that she angled the lamp. That she practiced. That she made the sign in clean block letters and positioned it for legibility and then stood in the broadcast-optimized corner of our stripped-down apartment and turned the camera on, alone, before dawn, in the specific quiet that exists only when she knew I was on my scavenging run and wouldn't be back for another hour. That she planned it that way. That she was going to do this and then be gone before I got home, and I would have walked into an empty apartment and found the note she would have left—because she would have left a note, she is meticulous about things like that—and the slot would have been locked and I wouldn't have been able to—
The intake counter ticks down. Twenty seconds.
"Mira," I say, and my voice does something I don't let it do, something that cracks along the bottom edge, and she flinches—just slightly, just enough that I see it—"don't do this."
"Someone has to." She says it without self-pity, which makes it worse. "And it's better me than—"
"Move."
"Kael—"
I cross the room in four steps. I'm bigger than her—I've always been bigger than her, taller and broader and I've always hated it, hated the way it makes her look smaller, hated the way the world is designed to make people like us fight each other for the scraps—and I put my hand on her shoulder and she resists, she actually digs in and resists, and for a second we are just two siblings in a falling-apart apartment at five in the morning fighting over who gets to sacrifice themselves while our mother is dying in the next room.
Then I shove her sideways, harder than I mean to, and she stumbles out of frame.
I step into the shot.
The unit is still in Mira's hand. The camera swings with her fall—a nauseating lurch of ceiling and cracked wall—and then it steadies because Mira catches herself and she is still holding the unit because even in freefall she did not drop it, fourteen years old and already conditioned to protect the device, and as the camera stabilizes it finds me instead.
Me. Standing where she was standing. Lit by the lamp she angled. Framed by the sign she made.
I look directly into the camera, which I have never done before in my life with any intention, and I say—
Nothing. I have nothing. I have not prepared anything because I have not planned anything because I have not had twenty seconds to plan anything. I am standing in my sister's broadcast with cold in my boot and my heart doing something geological and no idea what my face is doing right now.
The counter says six seconds.
Six seconds to the volunteer lock.
I hear Mira, off-camera, say my name in a voice that sounds like something breaking very quietly.
Five.
The sign is still there. ELLA VOSS. Eight hundred and forty-seven thousand credits. The gap between what the world says our mother is worth and what the world is willing to pay for it, written in black marker on a piece of cardboard by a fourteen-year-old who angled the lamp.
Four.
I'm still looking at the camera. At whoever is watching. The counter has passed twelve hundred now—it has passed twelve hundred and it is still moving, because the algorithm found us, the algorithm is always finding things, and whatever it sees in my face right now it is apparently hungry for.
Three.
Mira says, very quietly: "Kael, please."
Two.
I think of my mother's hands. How they looked last week, holding the rejection letter from the Zone 12 Medical Allocation Board. The thin particular stillness that came over them, like she had been expecting it, like she had been practicing for the exact weight of that news.
One.
The lock confirms with a sound like a door closing.
The stream does not clip. The stream does not clip because a thousand and eight hundred and—the counter is moving too fast to read—people are watching an unverified, untagged, algorithmically invisible seventeen-year-old from Zone 12-Gray stand in front of a handwritten sign in bad light and say nothing at all, and the nothing is apparently the most watchable thing on the entire network right now.
Mira lowers the unit slowly. The camera drops to waist height, catching my boots, the cracked floor, the cardboard sign. Her breathing is audible on the feed—fast and uneven and completely unfiltered, because she did not put on a condenser mic, because she did not plan for this part.
"They confirmed you," she says. Not a question.
"Yeah."
"Kael."
"Yeah."
I sit down on the floor. I don't plan that either—my knees just make a decision without consulting me, and the floor is cold through my jeans and the split in my boot sole is leaking cold too and I am sitting on the floor of our apartment in Zone 12-Gray at five in the morning and I have just volunteered for the Meridian on my fourteen-year-old sister's live stream.
The feed counter is at four thousand. Then seven. Then—
It is moving very fast now.
I look up at Mira. She is still standing, still holding the unit, and in the lamplight she looks very young and very angry and her eyes are doing something that isn't quite crying but is adjacent to it, close enough that I can see the effort it takes to hold it back. The blue jacket's cuffs are rolled twice. Her left hand is still a fist.
"The lamp," I say, because I cannot say anything that matters yet. "Where did you learn to angle the lamp?"
She stares at me. "Feed tutorials," she says. "Zone 8 broadcasting curriculum. I found an open archive." A pause. "I've been watching them for three months."
Three months. She's been planning this for three months.
The feed counter passes thirty thousand and the algorithm is still hungry and somewhere in the building, in the room beyond the thin wall that separates the kitchen-slash-living-room from the space we call a bedroom, our mother is asleep, and she does not know yet that one of her children just made herself a target and the other one stepped in front of the bullet, and the whole world watched it happen, and none of us signed anything yet.
My hands are flat on the cold floor. I notice they are shaking. I put my palms down harder and wait for it to stop, but the floor just transmits the cold and the shaking doesn't stop.
On the cracked screen of the shared unit, partially visible in the corner of the shot that Mira is still, absently, broadcasting: six minutes and forty-one seconds since the lock confirmed.
The feed counter is at eleven million and climbing.
