Zara stopped breathing for a second. Then she turned to the page where she'd written about the tower.
*Thu — crane all day. big antenna thing going up on the main building roof. tech guys everywhere.*
Three days ago. A Thursday.
She closed her eyes and replayed it. The tower crew had been there Tuesday too — no, wait. She flipped back. *Tue — more work on roof, cables.* Then nothing Wednesday. Then the crane Thursday. The install had finished three days ago, and the glitches had been happening for three weeks, always Tuesday and Thursday afternoons, always two to four.
"No," she whispered to the empty overpass. "Not three days. Longer."
The traffic roared overhead, and somewhere a horn blared, and Zara sat very still in the orange light, her mind running the way it ran when she was counting change at a register she'd never get to work — fast and careful at once.
She thought hard, the way she'd learned to think when a foster house got loud and she needed to plan. The communications tower — the one that was *finished* three days ago — had been going up in stages. Before that, there'd been the temporary mast, the calibration antenna they'd mounted on the scaffolding while the main tower was built. She remembered now: a smaller pole, blinking yellow, standing on the roof for weeks. She'd drawn it in the margin of a page in early October without knowing what it was.
She remembered something else. Two weeks ago, eating a sandwich by the fence, she'd overheard two tower technicians arguing about their schedule. One had said, *"The carrier says Thursday,"* and the other had said, *"Then we test-burst Tuesday and Thursday, two to four, till the array's certified."*
Test bursts. Tuesday and Thursday. Two to four.
Zara's pencil hovered over the page. Her hand was shaking, and she wasn't cold.
The glitches matched the tower's calibration bursts exactly. Every one of them. The tower fired its test signal, and the car's sensors went crazy — the warning lights, the stutters, the flickering dash. She didn't know the engineering words for it, but she knew the shape of it: the tower was screaming, and the car was listening on the same frequency. The car's brain — the AI sensor bus, she'd heard one engineer call it — was getting scrambled by the tower's harmonics, like trying to hear a whisper next to a siren.
She sat there a long time. A truck passed overhead and the whole overpass shuddered, dust sifting down onto her shoulders, and she didn't brush it off. Her heart was doing something strange — not fear, not exactly. Something she hadn't felt in a long time. It felt like being the only one awake in a burning building, holding the only map.
She was thirteen. She was homeless. She had a notebook held together with tape and a pencil chewed to a stub, and she had just solved the problem that twenty engineers with PhDs hadn't even seen. The thought should have made her feel powerful. Instead it made her feel tired, the deep-down tired of someone who already knew what came next.
Then she did what a thirteen-year-old homeless girl does when she's solved the puzzle nobody paid to solve: she laughed, once, a short bitter sound, and said out loud to the traffic roaring overhead:
"They'll never listen to me."
She knew exactly how it would go. She'd walk up to the gate and say, *It's the tower, your bursts are scrambling the sensor bus,* and the guard would look at her clothes and her shoes and say *scram*. She'd tried once before, months ago, to tell a maintenance man the fence camera was loose, and he'd told her to go beg somewhere else.
"Yeah," she said quietly to no one, "that's how it always goes."
So she wouldn't tell them. She'd wait. The big demo was tomorrow. The tower crew would fire a full burst during the rehearsal — she'd heard them say the final certification test was scheduled for the afternoon — and when the car died in front of everybody, they'd need an answer, and she'd be the only person on earth who had it.
She opened the notebook to a fresh page and wrote, in her neatest letters:
*Give me a minute. That's all I need.*
Chapter 7
The Death of the Prototype
The rehearsal was supposed to be theater — a dress run for tomorrow's investors, nothing more.
Richard Hawthorne stood in the control room at 2:15 p.m. watching the Meridian circle the track with the smooth confidence of a predator that had never been hungry. The marketing team had arranged the presentation deck on the big screen. Marcus Hale's assistant had confirmed: the man himself would arrive at nine sharp tomorrow, checkbook and skepticism in equal measure. Everything was ready. Everything was perfect.
Hawthorne's hands were folded behind his back, the posture of a man posing for a photograph that hadn't been taken yet. Somewhere in the back of his mind his father's voice was saying *listen to her, Richie,* and he told it to shut up. The car was perfect. The numbers were perfect. The day was perfect.
Then the tower fired.
Zara felt it before she saw it — not the signal itself, which was invisible, but the sudden pressure in the air, the way the red beacon on the roof flared from slow blink to solid burn. The full certification burst. She'd been watching the tower crew all morning from her spot behind the water tower, and she'd seen the technician give the thumbs-up, seen the engineer at the rooftop console throw the switch.
Her stomach dropped out from under her. *Now. It's happening now.*
