Chapter 1

*Clean?* I thought, the air whipping my skin raw. *You call this clean, you coward?*

I remember the feeling of the wind trying to peel the skin off my face. I remember the laughter of my cousins echoing from the rim—the people who shared my blood and had just helped Lucas tie my hands. I remember the sheer, blinding rage that drowned out the fear.

Then the Void hit.

It wasn't like hitting water. It was like being swallowed by a million freezing needles. The darkness wasn't just an absence of light; it was alive. It had teeth. I felt something wet and cold clamp onto my ankle, dragging me deeper into the crushing pressure.

"Help!" I tried to yell, but the sound was sucked right out of my throat.

I slammed into a floor of obsidian glass with a crack that sounded like my ribs giving up. I lay there, gasping, my lungs feeling like they were filled with shards of ice. Around me, the darkness pulsed. It breathed. And in the center of that breathing void, something was waiting.

"Who's the little piece of trash they threw down here?"

The voice didn't come from ears. It vibrated inside my skull, deep and heavy, like a landslide of velvet and gravel.

I rolled onto my back, coughing up something that tasted like copper and old coins. A few feet away, a figure emerged from the shadows. He didn't walk; he manifested. Tall, lean, with skin the color of a bruised storm and eyes that burned like dying stars. He wore black silk that flowed like liquid ink, clinging to a frame that looked built for war.

"I'm not trash," I spat, though my voice was a pathetic rasp.

He paused, tilting his head. A slow, dangerous smile curled his lips. "Oh? You're bleeding from every pore, your lungs are collapsing, and you've been discarded like a broken toy by your own kin. And yet, you're talking back. Interesting."

He stepped closer. The temperature dropped twenty degrees. I tried to scramble back, but my leg gave out. The Void's teeth were still sunk into my calf, draining the warmth from my blood.

"Get away from me," I snapped, trying to pull my hands apart. The ropes were charred, half-burnt by the fall, but still tight.

He knelt beside me, his movement fluid and predatory. He didn't touch me, but I could feel the heat radiating off him—a strange, paradoxical heat that promised both salvation and incineration. He leaned in, his face inches from mine. I could smell ozone and something ancient, like a library that had been underwater for a thousand years.

"You're dying, little bird," he whispered. His breath brushed against my lips, sending a shiver down my spine that had nothing to do with the cold. "In about three minutes, the Abyss will finish eating your legs and move up to your heart. Unless, of course, you want to make a deal."

"A deal?" I laughed, and it turned into a wet cough. "I don't have anything to give you."

"Wrong answer," he murmured. He reached out, his long fingers grazing my jawline. His touch was electric, a jolt of pure power that made my vision snap into focus. "You have life force. Pure, stubborn, spiteful life force. And I? I'm starving."

I glared at him. "You want to eat me? Just get it over with."

"Eat you? Please. That's so primitive." He chuckled, a low vibration that seemed to shake the very floor we were on. "I want a battery. A tether. I give you the power to climb back up that hole and burn every single person who pushed you into it to ash. In exchange, I get to feed on your vitality. A little bit every day. A sip of your soul to keep me anchored."

I stopped breathing. "You can give me that power?"

"God-tier power," he said, his eyes glowing brighter. "The kind that makes kings tremble and empires crumble. You wouldn't just survive, Ella. You'd be the thing they fear in the dark."

"Why help me?" I asked, my voice trembling. "What's the catch?"

"The catch is that you'll belong to me," he said, his voice dropping to a lethal, intimate register. He leaned closer, his chest almost touching mine. I could feel the thrum of his power, a heavy beat that matched the frantic rhythm of my own heart. "You'll be my shadow. My puppet. My little spark in this endless night. If I tell you to kneel, you kneel. If I tell you to kill, you kill."

I thought of Lucas. I thought of the way he'd looked at me—like I was a smudge on his shoe. I thought of the cousins who had laughed while I fell.

"I don't kneel," I whispered.

"We'll see about that," he replied.

He shifted his weight, pinning me down with the sheer pressure of his presence. He wasn't touching me with his hands, but I felt trapped, cornered by the gravity of him. The power imbalance was absolute; he was a god in a wasteland, and I was a broken girl in rags.

"Do we have a deal, little spark? Or should I let the Abyss finish its meal?"

I looked at the black teeth of the Void, still gnawing at my leg. I looked back at the man—Cain, though he hadn't told me his name yet, it felt etched into the air around him.

"Deal," I hissed. "Give me the power, and I'll give you whatever you want."

"Careful," he warned, his gaze dropping to my lips for a fraction of a second. "'Whatever I want' is a very dangerous promise to make to a monster."

Before I could respond, he moved. It was too fast to follow. One moment he was leaning over me, and the next, his hand was slammed against the obsidian floor beside my head, his body hovering over mine. He didn't touch me, but the proximity was suffocating. I could feel the heat of his skin, the scent of him filling my senses.

"Now," he commanded. "Hold your breath. This is going to hurt."

He didn't wait for me to comply. He reached out and gripped my wrist, his fingers like iron bands. He didn't pull me; he pushed his energy *into* me.

It felt like liquid fire pouring into my veins. I arched my back, a scream finally tearing from my throat as the power collided with my soul. It wasn't a gentle merge. It was a violent invasion. I could feel him—not just his power, but his hunger, his ancient loneliness, his suffocating dominance.

*Mine,* a voice echoed in my mind. *You are mine now.*

I fought it. I clawed at the air, my nails scratching the glass floor, but the fire only grew. It burned away the cold, burned away the fear, and replaced it with something sharp and jagged. Power. Raw, unfiltered destruction.

As the surge peaked, a black mark began to etch itself into my skin, right over my heart. It felt like a brand, a searing seal that locked us together.

Suddenly, the pressure vanished. Cain pulled back, standing up in one fluid motion. He looked down at me, his expression unreadable, though there was a flicker of something—satisfaction? Amusement?—in those burning eyes.

"Welcome back to the living," he said, his voice now a purr. "Though you're more dead than you were five minutes ago."

I sat up, shaking. I looked at my hands. Faint wisps of black smoke were curling off my fingertips. I felt... different. Stronger. And terrified.

"How do I get out?" I asked, glancing up at the distant, tiny pinprick of light that was the world above.

"Oh, you're not walking out," he said, a dark smirk playing on his lips. "We're going to take the scenic route. But first..."

He leaned down again, his face inches from mine. He didn't touch me, but he was so close I could feel the heat of his breath on my cheek. He reached out, his finger hovering just a millimeter away from the seal on my chest.

"I can feel your heart beating, Ella. It's so fast. Are you scared? Or is it something else?"

I glared at him, refusing to flinch. "I'm pissed off. There's a difference."

"Is there?" He chuckled. "I think I'm going to enjoy this."

He straightened up, and for a moment, the shadows around him flared like wings. The ground beneath us began to tremble. The Void wasn't happy that its meal had been stolen.

"The Abyss wants its tribute back," Cain said, glancing at the encroaching darkness. "And it's bringing friends."

From the gloom, dozens of pale, spindly creatures began to crawl toward us, their mouths wide and filled with needle-teeth. They didn't make a sound, but the air grew heavy with the smell of decay.

I scrambled to my feet, my legs still shaking. I didn't know how to use the power, but as the first creature leaped, I didn't think. I just swung my arm.

*Boom.*

A blast of black kinetic energy erupted from my palm, slamming the creature into the wall with enough force to shatter the obsidian. The shockwave knocked me back, but I didn't care. I stared at my hand, a manic grin spreading across my face.

"Did you see that?" I yelled, looking at Cain.

He didn't look impressed. He looked bored. "You're leaking energy like a cracked pipe. If you don't learn to control it, you'll blow yourself up before we even reach the surface."

"Then teach me!" I snapped.

"I'm not a teacher, little spark. I'm a landlord. And you're just the tenant."

He stepped in front of me, his back to the monsters. He didn't even look at them. He just raised a hand, and the shadows rose like a tidal wave, swallowing the creatures whole in a single, silent gulp.

He turned back to me, his eyes narrowing. He stepped into my personal space, forcing me to back up until my spine hit a jagged pillar of rock. He didn't touch me, but he boxed me in, his arms resting on the stone on either side of my head.

"The seal is almost set," he whispered, his voice vibrating in my chest. "But there's one more thing. The Abyss doesn't let go easily. It's still holding onto you."

I looked down. The black teeth of the Void were still clamped onto my leg, the skin around the wound turning a bruised, necrotic purple.

"What do I do?" I asked, my voice trembling.

Cain leaned in, his lips almost brushing my ear. "You don't do anything. I do."

He reached down, his hand gripping my calf. The contact was searing. He didn't pull the teeth out—he crushed them. I gasped, my body jolting as he ripped the Void's hold from my flesh.

He didn't let go. His hand stayed there, his thumb pressing into the wound, a strange, possessive grip that made my blood sing.

"Now," he said, his voice low and dangerous. "The seal is one inch from your heart. If it closes, you're mine forever. If it doesn't... you're just a corpse with a fancy trick."

I looked at the mark on my chest, the black ink pulsing like a second heart.

"Wait," I said, a sudden thought hitting me. "If we're bound, can you feel what I feel?"

Cain's gaze darkened. He moved his hand from my leg to my waist, pulling me flush against him. The friction of his silk clothes against my ruined dress sent a jolt of electricity through me. He leaned down, his forehead resting against mine.

"I can feel everything, Ella," he whispered. "And right now, your heart is screaming for revenge."

He let go of me abruptly, the cold air rushing back in. He pointed upward.

"Let's go. I want to see the look on your family's faces when the trash they threw away comes back to collect the debt."

I started to follow him, but a sudden, sharp pain flared in my chest. I gasped, clutching my heart.

"What is it?" Cain asked, his voice losing its boredom.

I looked down. The seal wasn't closing. It was vibrating, and a thin line of crimson blood was leaking from the center of the mark.

"It's... it's fighting me," I managed to say.

Cain frowned, stepping back toward me. He reached out to touch the seal, but before his fingers could make contact, the ground beneath us gave a violent lurch.

"Too late," he muttered. "The Abyss just changed the locks."

Above us, the pinprick of light vanished. A massive slab of obsidian slammed shut, sealing the exit.

And then, from the darkness behind us, a voice called out—a voice that sounded exactly like Lucas.

"I told you it was cleaner if you just fell, Ella."

I spun around, my heart hammering. But there was no Lucas. Only a towering, distorted mirror image of him, eyes glowing with a void-light that made my skin crawl.

"What the hell is that?" I yelled.

Cain stepped in front of me, his voice cold. "That's not your ex. That's a Void Sentinel. And it's not here to talk."

The creature roared, a sound that shattered the remaining glass pillars around us. It lunged, a blur of grey flesh and claws.

Cain didn't flinch. He grabbed my hand, his grip tight and commanding.

"Use it!" he roared. "Push the power out or we both die here!"

I closed my eyes, reaching for that fire in my veins. I felt it—the jagged, angry heat. I pushed. I pushed with everything I had, screaming as the energy tore through my arm.

But as the blast erupted, I felt something else. A tug. A pull.

The seal on my chest didn't close. It opened wider, and something from the darkness—something that wasn't Cain—reached through the gap and gripped my soul.

"Got you," the thing whispered in my head.

Cain's eyes widened. "Ella!"

He lunged for me, but the Void Sentinel's claw was already mid-swing, aimed straight for my throat—
