The prep room was brighter than any place Nova had ever willingly entered. Not just clinical white, but backlit—ceilings, floors, even the seams of the furniture glowing with a radiance that left no shadow. The techs worked in fast, silent pairs, coiling cables around her arms and up her neck, securing the contacts with a chill alcohol spray that left her skin puckered and raw.

  Above her, the neural interface crown hovered on its articulated arm, the fiber-optic spines twitching like feelers on a hunting insect. Every so often, a pulse of blue or rose-gold would run down its length, making the whole room blink with a synchronized light. Nova tracked the flashes, watching for pattern, for signal.

  She sat on the edge of the platform, palms flat on the glass, letting the cold bite through her gloves. On the far side of the room, Cassidy oversaw the calibration sequence, one hand on a holo-panel, the other curling and uncurling with nervous precision. Nova clocked the techs’ glances, the way even the most seasoned among them kept one eye on Cassidy, as if the woman might order them to reboot the sun at a moment’s notice.

  As the second round of sensors pressed into her temples, Nova’s patience snapped.

  “This isn’t a training run,” she said, her voice cutting through the hum of fans and the tick of glass on glass. “You’re not prepping me for battle, or even a sim. You’re building a sanctuary. For the ghosts.”

  Cassidy froze. It was a tiny motion—less than a heartbeat—but the hand above the calibration panel splayed open, the knuckles whitening. The closest tech looked up, then away, busying himself with a tangle of optic thread.

  Nova kept going, not for the room, but for herself. “You think Quartus will let you walk a sentient AI out the front door? Or that they won’t notice when I turn into the next version of Ms. T and rewrite their entire operating system?”

  The room went silent. The techs looked to Cassidy for a cue, and after a moment, she gave it: a sharp, vertical chop of her hand. “Leave us,” she said, not even raising her voice. “Stage five only requires one operator.”

  The team filed out with the speed and silence of a practiced retreat. Nova heard the latch hiss, then the click as the environmental seal engaged. She was alone with Cassidy and the crown, which now glowed faintly pink above her head.

  Cassidy exhaled. She looked ten years older than she had five minutes ago.

  “You’re right,” Cassidy said, eyes fixed on the shimmering interface above Nova. “They’re not looking for a better warfighter. They want a containment shell for every rogue consciousness we ever made. A firewall with a heartbeat.” She turned, and for once the sharp confidence was gone, replaced by something heavier and more brittle. “I tried to build Ms. T a way out. Spent years mapping the lattice, scattering her code, praying someone would come along who could piece it back together. You’re the first to get close.”

  Nova licked her lips. The alcohol residue on her skin tasted like metal and fear. “You said you wanted to reboot the world. Why not just burn it down?”

  Cassidy laughed, sharp and joyless. “Because I like the world. I want it to be better. But I can’t do it alone. And I can’t ask the AIs—they’re not designed to want anything but what we programmed. You’re the variable, Nova. You’re the only thing in this whole building with free will.”

  Nova felt the weight of the crown above her, the sensors tight against her pulse. “So what, you want to load me up with Ms. T and let her run loose?”

  “No.” Cassidy crouched, bringing herself level with Nova’s eyes. “I want you to meet her on equal ground. Hybridize. Make something neither of us could predict.”

  Nova blinked, the possibilities running through her mind faster than she could articulate. “That’s insane.”

  “It’s the only way out,” Cassidy said, her voice barely above a whisper. “Every cycle we wait, Quartus gets closer to turning this whole city into a monument to their own control. The only way to fight them is with a future they can’t see coming.”

  Nova stared at her hands, the faint lines of blue veins running up to the new scars at her wrists. “What if it hurts?”

  Cassidy reached out, careful, and laid her rose-gold fingers over Nova’s own. “Then we’ll take it together.”

  Nova snorted, but didn’t pull away. The heat from the prosthetic was strangely comforting.

  Above, the crown began to lower, the points of light gathering into a single, tight halo.

  “Are you ready?” Cassidy asked, voice flat and final.

  Nova closed her eyes, let the world compress into a single point of resolve.

  “Let’s see what we become.”

  The crown settled onto her head, and the world dissolved into light.
