Chapter 1: Zero

The pit smelled like blood and desperation.

Zara Chen, Zero to the crowds and nobody to herself, bounced on her toes in the fighter's circle, watching her opponent through the cage's electrified mesh. The woman across from her was bigger, augmented with obvious muscle grafts that made her arms look like they'd been stolen from a gorilla. Street-level work, probably done in some back-alley clinic with more ambition than skill.

In the pits, that usually meant dangerous. Desperate people got cheap augments. Cheap augments made desperate people even more desperate when they realized they'd traded their savings for hardware that would burn out in six months.

"Ladies and gentlemen!" The announcer's voice boomed through speakers that crackled with age. "In the red corner, standing at six-foot-two, carrying enough chrome to plate a hover-car—the Crusher!"

The crowd roared. The woman, the Crusher, raised her massive arms and flexed. Under the pit's flickering lights, Zara could see the seams where her skin met metal. Infection waiting to happen.

"And in the blue corner, our reigning champion of the Underground Circuit, holder of seventeen consecutive victories, the woman with no past and no mercy—Zero!"

Zara didn't flex. Didn't pose. She just stood there, five-foot-six of lean muscle and hidden modifications, watching the Crusher the way a cat watches a bird that hasn't realized it's already dead.

The bell rang.

The Crusher charged.

Zara had been fighting in the pits for two years, as far back as her memory went. She didn't know where she'd learned to fight like this. Didn't know why her reflexes were faster than any normal human's, why her body moved in ways that felt more machine than flesh, why sometimes, in the darkest hours of the night, she dreamed of blood that wasn't her own.

She only knew that when she fought, everything made sense.

The Crusher's first punch was telegraphed a mile away. Zara slipped beneath it, feeling the wind of the blow ruffle her close-cropped hair. Her counter was already moving: three quick strikes to the woman's side, finding the gaps between her muscle grafts where the nerve bundles ran exposed.

The Crusher screamed and swung wildly. Zara danced back, patient. Let the woman exhaust herself against empty air. Let her get angry, sloppy, desperate.

"Stand still, you little bitch!"

Zara said nothing. Words were wasted energy. She'd learned that somewhere, couldn't remember where, and the lesson had stuck.

Three more exchanges. Three more times the Crusher swung and missed while Zara's precise strikes found their marks. The big woman was slowing now, her augmented muscles overheating, steam literally rising from the vents in her shoulders.

Time to end it.

Zara moved. Not fast—*impossible*. One moment she was three feet away, the next she was inside the Crusher's guard, her palm pressed against the woman's sternum. She felt the heartbeat beneath her fingers, strong and panicked.

"Yield," Zara said quietly.

"Fuck y—"

Zara's fingers found the neural port hidden beneath the Crusher's hair and *pressed*. Not hard enough to cause permanent damage, she had rules about that, but enough to send a jolt of feedback through the woman's central nervous system.

The Crusher dropped like her strings had been cut.

The crowd went silent for a heartbeat, then erupted into cheers and curses in equal measure. Money changed hands. Bookies scrambled to calculate odds. In the VIP section, a series of raised platforms with actual chairs instead of standing room, the real players watched with calculating eyes.

Zara ignored all of it. She climbed out of the pit, grabbed the threadbare towel from her corner, and headed for the back rooms without looking at anyone.

"Zero! Zero, wait up!"

She didn't slow down, but Jin caught up anyway. The kid always did. Fourteen years old, gender indeterminate, and possessed of more digital skills than most corporate deckers twice their age. Jin had been haunting the Underground for six months, ever since Zara had stopped a group of organleggers from taking the kid apart for parts.

"That was amazing! The way you moved at the end, that wasn't even human, that was like—"

"Jin." Zara's voice was flat. "What do you want?"

The kid's enthusiasm dimmed, but didn't die. It never did. "Mercy wants to see you. Said it's important."

Zara frowned. Marcus Webb, Mercy to everyone in the Underground, didn't summon fighters for idle conversation. He ran the pit fights, which meant he ran the whole Underground, which meant when he called, you answered.

Unless you wanted to find out how quickly an empire of secrets could make you disappear.

"Where?"

"His office. He's got a guest." Jin's voice dropped to a whisper. "Some corpo suit. Came down through the service tunnels, all cloak and dagger. I think—"

"Don't think." Zara softened the words by ruffling Jin's hair. The kid didn't have anyone else, and she knew what that felt like. "Just tell me what you see. Thinking gets you in trouble."

"Okay, well, what I *see* is a guy who looked like he was dying. Like, actually dying. Skin all gray, hands shaking. And he was carrying something. A case, bio-locked, looked like it was worth more than this whole building."

A dying man with expensive cargo, seeking out the lord of the Underground. That couldn't be good.

"Stay out of sight," Zara told Jin. "If things go bad, run to Dr. Chen's clinic and don't come back until I send for you."

"But—"

"Jin."

The kid's shoulders slumped. "Fine. But you better not die. I still haven't figured out how you did that thing with the neural port."

Zara almost smiled. Almost. "I'll try not to."

---

Mercy's office was a converted maintenance bay, three levels up from the pit. The walls were lined with screens showing feeds from across the Underground: fights, deals, movements, the unbroken churn of people in Neo Meridian's lower city trying to survive another day.

Marcus Webb sat behind a desk made from the hood of a vintage ground-car, his wheelchair folded beside him. He'd lost his legs in the corporate wars, back when he'd been company muscle instead of their enemy. Now he ran the largest independent information network in the lower city, and he did it without ever leaving this room.

"Zero." His voice was the same gravel it had always been. "Thanks for coming."

"You asked."

"I did." He gestured to the figure slumped in the chair across from him. "This is Marcus Ashford the Second. I believe he has something to discuss with you."

Zara's eyes went to the dying man, and froze.

She didn't recognize his face. She'd never seen him before, she was certain of that. But something in her mind *twisted* at the sight of him, like a key trying to find a lock that didn't quite fit.

Marcus Ashford was young, probably not even thirty, but whatever was killing him had aged his features decades. His skin had the waxy quality of someone whose organs were shutting down one by one. His eyes were sunken, bloodshot, but still sharp with intelligence and fear.

He was afraid of her. Terrified, actually. But he wasn't running.

"Ms. Chen," he said, and his voice was surprisingly strong. "Or do you prefer Zero?"

"I don't prefer anything. What do you want?"

"To give you back your life." He lifted the case Jin had mentioned, his hands trembling with the effort, and placed it on Mercy's desk. "And to ask you to finish mine."

The case opened with a soft hiss. Inside, nestled in foam padding, was a neural interface unlike anything Zara had ever seen. It looked like a crown made of liquid mercury, constantly shifting and reforming.

"That's a memory transfer device," Mercy said quietly. There was something in his voice, not fear exactly, but close. "Corporate-grade. The kind they use for—"

"For backing up the minds of people who can afford to live forever." Ashford laughed, which triggered a coughing fit that left flecks of blood on his lips. "Yes. I stole it from my mother's personal vault. Along with... other things."

"Why?"

"Because she killed me." Ashford met Zara's eyes, and she felt that twisting sensation again, stronger this time. "She killed me, and she killed you, and she killed a hundred thousand others whose memories she fed to her machines so she could keep living in stolen time."

Zara's hand went to her head instinctively, to the scars hidden beneath her hair where neural ports had been installed and removed, installed and removed, a dozen times over. She'd always assumed they were from the pits, from some forgotten injury.

What if they weren't?

"Who am I?" The words came out before she could stop them.

Ashford smiled sadly. "That's what I came to tell you. What I came to *show* you." He touched the device. "This holds my memories. Everything I know about the Ashford Dynasty, about my mother's crimes, about Project Ghost—and about you. Who you were. What you did. Why they erased you."

"And why would you give me this?"

"Because I'll be dead within the hour, and you're the only person who might be able to use it." He started coughing again, worse this time. "I need... you need to see..."

His hand shot out, faster than a dying man should be able to move, and grabbed Zara's wrist. Before she could pull away, he pressed something, a needle, she realized too late, into her skin.

Then his eyes rolled back, and Marcus Ashford the Second died in Mercy's office.

But not before the transfer began.

Zara screamed as foreign memories poured into her mind like molten metal. Flashes of faces she didn't recognize but somehow knew. Corporate towers. Hidden labs. A woman with ice-cold eyes and a smile like a knife—*Eleanor, Mother, the spider at the center of everything*—and worse, so much worse—

*She was standing in a room full of bodies. Her hands were red. Her mind was empty.*

*"Excellent work, Specter," a voice said. "Target eliminated. Proceed to extraction."*

*She stepped over the corpses of a family—father, mother, two children—and felt nothing. Nothing at all.*

The memory shattered. Zara found herself on the floor, Mercy's worried face swimming above her, alarms blaring somewhere in the distance.

"Zero! Zero, stay with me!"

"I..." Her voice didn't sound like her own. "I remember..."

She remembered her name. Her real name. The one they'd taken from her.

She remembered killing for the Ashfords. Dozens of times. Hundreds. She'd been their weapon, their ghost, their perfectly empty vessel.

And then she'd discovered something. Something that made her run. Something worth dying for.

Something they'd ripped from her mind before throwing her away like broken hardware.

"I remember," she whispered again. Then, stronger: "I remember everything."

The alarms weren't coming from inside the office.

They were coming from above.

"Mercy." Her voice was steady now, cold in a way it had never been before. "How many exits does this building have?"

"Six. Why?"

*Specter.* The name settled into her newly-unlocked mind like a key finding its lock. She climbed to her feet. Her body moved differently now, flowing like water, like shadow. Two years of fighting in the pits, and she'd never known what she truly was.

She knew now.

"Because the Ashfords just found their stolen property." She grabbed the memory device from the desk, Ashford's final gift, worth more than the whole Underground combined. "And they're going to burn this whole building down to get it back."

The first explosion hit three seconds later.
