It was the smell of burning hair that got me first.

I was back in the square, the wood grain of the closet door biting into my palms as I stared through the crack. My mother looked so small, a fragile slip of grey linen against the stake. The Holy Fire didn’t burn red; it was a blinding, incandescent white that hissed as it climbed her hem.

She didn't scream. She just looked at the closet, her lips moving in a silent, desperate command: Hide, Lillian. Don't breathe. Don't let them see your eyes.

The crowd was a wall of cheering shadows, but the man in the front row was different. He wore the black robes of the Inquisition, a silver cross catching the firelight. He turned his head, and his eyes weren't filled with God—they were filled with the deep, frigid sea.

Linus Kerr.

He walked toward my hiding place, the Cold-Iron chain in his hand giving a rhythmic, deathly clink against the cobblestones. "Found you, little witch," he whispered, his voice a freezing rasp. He thrust a burning torch into the closet—

"NO—!"

I bolted upright, a shattered scream tearing through my throat. I gasped for air, but my lungs felt like they were filled with hot ash. I was drenched in sweat, my linen shirt sticking to my skin like a second, suffocating layer.

The nightmare had triggered the resonance. My blood felt like molten lead, surging through my veins with a pressure that threatened to burst my heart. I was incinerating from the inside out.

The Cold-Iron chain thrashed frantically, striking the mahogany bedpost with a series of sharp, terrifying clanks. I couldn't tell the difference between the dream and the room. I felt the collar tightening, a band of ice trying to choke a fire that wouldn't die. I clawed at my neck, my fingernails digging into my own skin, trying to pull off the torch I thought was pressing against my throat.

"Let me go... please, don't burn me..."

BANG.

The door was thrown open. A dark silhouette surged into the room like a winter gale.

Linus didn't look like he’d been sleeping. He was a man who probably treated the night like a different kind of battlefield. He saw me huddled in the corner of the bed, flailing at the air, and he didn't hesitate. He lunged across the mattress.

He seized both of my wrists in one hand, pinning them against the sheets with a grip that felt like a steel vice.

"Let go! Get away!" I shrieked. My vision was a smear of red and black. "Don't burn me... Mother... don't let them..."

I thrashed against him, my body slick with sweat, trying to buck him off. My knee slammed into his ribs, but he didn't even grunt. He was a mountain of solid muscle and cold wool, and he used every ounce of his weight to nail me into the mattress.

Absolute, crushing suppression.

His glacial chest pressed flat against my heaving, burning curves, forcing the air out of my lungs. The contrast was a violent shock—like being thrown into a frozen lake while your skin was on fire.

"Look at me!" Linus roared against my ear, his voice a low, commanding rumble that cut through the panic. "There is no fire! Lillian, look at me! You are in the Tower! Look at my eyes!"

The familiar scent of cedarwood and cold air hit me. My struggles weakened, my breath coming in ragged, sobbing hitches. My pupils finally focused, reflecting the hard, indigo face looming inches from mine.

No torch. Only Linus.

"Lin... Linus?" my voice was a broken thread.

"It's me."

He didn't move. He stayed there, pinning me down, his thighs locking mine in place. I could feel the rapid, heavy thrumming of his heart against my own.

"Cold..." I whispered, the fire in my blood still flickering. "So cold..."

Linus let out a heavy, jagged breath. He released my wrists but didn't leave. He pressed his bare, icy palm against my forehead. Biting, glorious ice. I chased the sensation instinctively, turning my head to nuzzle into his hand, my tears wetting the rough skin of his palm.

"Don't go..." I reached out and grabbed the lapel of his silk robe, my knuckles white. "Don't leave me alone in the fire."

I felt him freeze. The man who hunted my kind for a living stood still, his hand anchored to my face. For a long, silent minute, the only sound was the wind rattling the windowpanes.

"I'm not going anywhere," he whispered. His voice was so raspy I barely recognized it.

He shifted, lying down on his side and pulling me—duvet and all—into the iron circle of his arms. "Sleep."

He rested a heavy hand on my back, patting me with a slow, clumsy rhythm. His body temperature was a steady drain, siphoning the fever from my marrow. I curled into him, my nose pressed against the cold skin of his chest, listening to the click-tick of the machine behind his ribs.

A few minutes later, the edge of the overload finally faded, leaving me exhausted and hollow.

I shifted in my sleep, my body seeking the coldest patches of his skin. My leg hooked over his waist, and my hand slid beneath the hem of his robe, searching for the glacial heat of his abdominal muscles.

I heard him suck in a sharp, pained breath. His entire body turned to granite beneath my touch.

"...Fuck."

He hissed the curse into the darkness. I was too far gone into the shadows of sleep to care about his dignity, or mine. I just held onto the ice, desperate to keep the fire away for one more night.

I didn’t wake to the light. I woke to a weight that was too heavy, too solid, and far too intoxicating for my own survival.

My vision was a hazy blur of silver hair against a black silk pillowcase. For a confused second, I thought the fever had finally melted my brain, but the scent was too real—the sharp, biting aroma of cedarwood and the underlying, perennial frost of the Tower.

Then, I realized what my body was doing.

I was draped over Linus Kerr like a drowning woman clinging to a spar. My leg was hooked unceremoniously over his waist, and my hand—the same hand that had spent years delicately grinding herbs—had strayed beneath the silk lapel of his robe. My palm was pressed flat against the bare, chilling skin of his chest, directly over the rhythmic, mechanical click-tick of his heart.

I felt him go rigid beneath me. A sharp, hissed breath escaped his teeth, sounding like steam venting from a high-pressure pipe. Every muscle in his body turned to granite in a single heartbeat.

I looked up, my eyes crashing into a pair of stormy indigo irises that looked ready to incinerate me.

The silence was a deafening void. I realized exactly where my leg was resting, and against what. The hard, demanding reality of his body was a physical shock that sent a jolt of electricity straight to my gut.

"AH!"

I shrieked, scrambling backward in a blind, undignified panic.

CLINK—

The Cold-Iron chain snapped taut.

"Oof!"

The tension yanked me back before I could roll off the mattress. I tumbled forward, my momentum betrayed by the very leash he’d put on me. My lips grazed the rough, cold stubble of his jaw in an accidental, breathless caress. For a heartbeat, my face was so close to his that I could see the dark, jagged pupils of his eyes.

My face burned with a heat that had nothing to do with magic. I went as stiff as a board, my heart hammering against my ribs. "I... the... the chain caught..."

Linus didn't pull away. He reached out and clamped a hand around my waist, pinning me down to the bed with a force that ended all friction.

"Don't move," he rasped.

His voice was a haunted, lethal warning. It sounded like a growl from a predator holding back its own hunger by a thread. "Unless you want me to exercise my 'Owner's rights' right here and now."

He didn't wait for me to breathe. He rolled out of bed with the frantic efficiency of a man escaping a crime scene. He stood with his back to me, his broad shoulders blocking the morning light. He cinched his silk robe so tight it looked like a suit of armor.

"Ten minutes," he said, his voice returning to that clinical, distant cold. "Get yourself together. What happened last night... will not happen again."

The breakfast that followed was a masterclass in suffocating silence.

I sat at his right hand, the silver fork in my hand feeling like a lead weight. The silence was finally broken by Adjutant Silas.

"Sir," Silas reported, his boots snapping together. "An envoy from General Malles is here. There is a public execution in the square at noon—a suspected cell of 'Cinder-Walkers.' The General has requested Miss Wylde’s presence... as a guest of honor."

CLANG.

My fork clattered against the porcelain plate. The color drained from my face. "Guest of honor." I knew what that meant. Malles wanted to watch the "Nightingale" break as she watched her own kind turn to ash.

"I'm not going," I whispered, my fingers clawing at the white linen tablecloth.

"Tell the envoy she will be there," Linus said. He didn't even look up from his black coffee. His voice was as cold and flat as a tombstone.

"Silas, clear the subterranean training hall," Linus said, ignoring my protest entirely. "We leave in two hours."

Linus's private training hall reeked of stale sweat and cold stone. He had shed his vest and coat, standing in the center of the room in only a white shirt, sleeves rolled up.

"Take it." He tossed a wooden training dagger at me.

I caught it, but my hand was trembling. I was still wearing that emerald velvet dress—a heavy, suffocating cage of a garment with a hem that dragged like a ball and chain.

"The fire is coming, Lillian. It doesn't care about your tears. It only cares about how fast you burn," Linus said, stepping into my space. "If you go to that square as a victim, you'll be ash before they even light the match. I’m going to teach you to be the one holding the torch."

Without warning, he struck.

He didn't pull his punch. A lightning-fast sweep of his leg caught me across the shins. I tried to skip back, but the floor-length velvet skirt was too heavy, too wide. It tangled around my ankles like a wet shroud.

I went down hard. My face slammed into the padded mat, and the emerald fabric, now damp with my own frantic sweat, felt like it weighed fifty pounds. It was a beautiful, emerald-colored trap.

"Get up," Linus barked, looming over me.

"I can't... this dress..." I hissed, struggling to find my footing, only to trip on the thick velvet again. I tried to rip the fabric with my bare hands, but the high-grade silk and reinforced lining held firm, only bruising my fingertips.

Linus let out a dark, mocking scoff. He walked toward me, the heavy heels of his boots thudding on the mat. "A lady’s finery is a convenient excuse for a coward."

He reached down, his hand wrapping around the hilt of the Cold-Iron sword at his hip. I froze. He didn't draw the blade. Instead, he used the sharp, reinforced edge of the metal sheath.

"Stay still," he commanded.

He stepped between my tangled legs, the heat of him clashing with the drafty air of the hall. He hooked the edge of the sheath into the hem of my skirt and gave a sudden, violent upward jerk.

RIIIIIP.

The sound of the high-grade velvet tearing was a visceral, jagged scream. He didn't stop until the slit reached my mid-thigh, exposing my bruised skin and the white lace of my petticoat. He did the same to the other side with a clinical, terrifying efficiency.

"There," he whispered, his indigo eyes darkening as he looked at my exposed legs. "No more excuses."

Anger—hot, raw, and desperate—finally snapped in my chest. I didn't wait for him to move. I lunged, snatching the wooden dagger and aiming for the space between his ribs.

Linus didn't flinch. He caught my wrist mid-air, pinning me against the stone wall. He slammed his body into mine, caging me. One hand clamped around my throat—firm enough to let me feel the frantic, terrified pulse in my own neck—while the other pinned my wrist over my head.

"Listen to me, Lillian." He hovered over me, his sweat dripping onto my lip. "When the fire starts, the crowd will scream. The heat will try to melt your brain. Don't look at the pyre."

He seized my hand, forcing the tip of the wooden dagger against his own chest, right over the spot where his mechanical heart was thrumming like a starving beast.

"Think of me. Think of how much you want to kill me for what I've done. Turn all that terror into a blade. Stare at me. Only at me."

His voice was a low, hypnotic rumble that made the iron in my blood vibrate. "As long as you're trying to figure out how to cut my throat, you won't feel the flames. Am I the most terrifying thing in your world, Lillian? Answer me."

"Yes," I rasped, my voice sounding more like his than my own.

"Good." He released me and stood back, his gaze hungry. "Again. Throw yourself at me until you forget you're a victim."

The heat in the square wasn’t a metaphor; it was an assault.

Sweat stung the raw cuts on my legs—the ones I’d earned in the training hall this morning—and the salt made them burn with every step. My eyes throbbed from the glare reflecting off the ivory stone of the Cathedral. I stood in the high inquisitorial box, the emerald velvet of my dress feeling like a layer of wet, heavy moss. The corset was cinched so tight that every shallow breath felt like my ribs were grinding against one another.

"Don't blink," Linus whispered.

He stood beside me, a towering mass of black wool and cold iron. The silver sigils on his chest didn't look 'brilliant'; they caught the sun and threw the light back into my eyes, sharp and jagged, making a headache bloom behind my temples.

His hand didn't just 'snake' around my waist. He clamped his arm around me, hauling my body back against his side until I was forced to stand straight. To the thousands of people below, he was a protective fiancé. To me, his fingers were a vice, digging into my hip with a pressure that promised bruises.

"Watch the square," he rasped, his voice a low vibration against my ear. "Don't look at the crowd. Don't look at the smoke. Look at the horizon if you have to, but don't you dare faint."

In the center of the plaza, three black iron pillars rose from mounds of wood soaked in black, stinking oil. Three men were bound there, their faces hidden behind hoods that were already damp with their sweat.

Directly opposite us sat General Malles. He wasn't a saint; he was a vulture in a crimson uniform. He didn't look at the 'sinners.' He looked at me, his milky, cataract-filmed eyes scanning my face for the first sign of a crack. He wanted to see the witch bleed.

"Ignite," Malles said. It wasn't a command; it was a bored dismissal of life.

WOOSH.

The fire didn't just start; it roared. The air in the square was instantly sucked toward the pyres, replaced by a wave of heat that smelled of scorched grease and chemicals.

ARGHHHHH—!

The screams weren't human. They were high, wet, and raw—the sound of vocal cords being cooked.

In a heartbeat, the square vanished. I was back in that closet, the wood grain biting into my palms, watching the white flames lick my mother’s feet. My lungs seized. The air felt like I was breathing in hot sand. The resonance in my blood began to scream, a high-pitched metallic whine that made my teeth ache. I felt my knees give way, my body ready to collapse into a heap of emerald velvet.

"I said, look at me!"

Linus’s voice hit me like a slap. He didn't just turn me around; he wrenched me toward him, his massive frame blocking the view of the burning men. He seized my chin, his fingers cold and unyielding, forcing my head back until I had to look into those bottomless indigo eyes.

"Think of the cellar," he hissed, his face inches from mine. "Think of the mat this morning. Think of how much you want to kill me for what I’ve done. Use it, Lillian. Feed on it."

Hate. It was the only thing cold enough to fight the fire.

I focused on the bruising grip of his hand. I focused on the way he’d collared me like a dog. The anger was a shot of pure, bitter adrenaline. It was sharper than the fear, and it gave me a floor to stand on. I stopped shaking because I was too busy trying to figure out how to bury a knife in his throat. My fingers clawed into the wool of his sleeves, my nails digging deep into the muscle of his arms.

To the crowd, we were a scandalous tableau—the Inquisitor and his consultant lost in a moment of dark passion while the world turned to ash behind them. Malles’s lip curled in a sneer of irritation. He wanted a broken girl; he got a woman whose eyes were burning with a murderous focus.

Linus didn't pull away. He took my hand—the one that was trying to draw his blood—and didn't kiss it like a lover. He gripped it hard, his lips pressing against my knuckles with a cold, dry aggression. It wasn't a kiss; it was a brand. A marking of property in front of the world.

"You look like a blade, Nightingale," he whispered against my skin. "Stay sharp."

I shuddered, the cold of his lips lingering like a scar.

A new sound rose through the crackle of the flames—a low, rhythmic chanting. I turned my head. At the edge of the square, a woman in flowing white robes was moving through the masses. Agatha.

She held a staff topped with a massive, pulsing crystal. As she walked, the frenzied crowd fell to their knees as if she were a god walking the earth. She ignored the dying men; she ignored Malles. She stopped and tilted her head back, her gaze cutting through the smog to find mine.

There was no mercy in her face. Only a clinical, serpentine coldness.

She raised her hand and made a single, slow motion: a finger drawn across her own throat.

My pulse spiked, but not from terror. I felt it. A high-pitched, metallic thrumming in the marrow of my bones. It was the exact same frequency as the brass heart I’d pulled from the petrified corpse. It was the hum of a machine, not a miracle.

"Linus," I whispered, my fingers tightening on his vest. "The staff. Look at the crystal."

I looked up at him, my voice a jagged edge.

"I can feel the resonance. That thing she’s holding... it’s the same technology. The person who turned that dockworker to stone... she’s standing right there."

Linus narrowed his eyes, a lethal killing intent exploding in his gaze as he locked onto the woman in white.

The execution was over. The victims were ash. But as the smoke cleared, I knew the real hunt had just begun.
