Marrying My Cheating Fiance's Ruthless Uncle

Isabella POV

The morning after my culinary assassination attempt, Gina practically vibrated with nervous energy as she laced my corset in my suite.

"Leo told me everything, Miss," she whispered, her eyes wide. "After he threw the broth at the wall, Grayson didn't stay angry. Leo said he actually smiled. He asked Leo, 'Do you think she really wants to poison me, or is she just desperate for my attention?'"

A cold knot formed in my stomach. I had wanted to terrify him into breaking the betrothal. Instead, my sudden display of lethal intent had somehow bypassed his arrogance and ignited a sick, morbid fascination. He thought I was playing a twisted game.

"He thinks you're more interesting than Clara now," Gina added, her voice laced with disgust.

"If he wants a game, I will give him one," I murmured, though unease prickled my skin. "I'll use this new obsession to push him over the edge."

That evening, the exhaustion of another brutal session at the Trinity College shooting range weighed heavily on my bones. Gina and I were walking down the dim, Persian-carpeted corridor of The Villa, the shadows stretching long against the oil paintings.

"We need to adjust the plan," I told Gina quietly. "If Grayson is looking for my attention, I will suffocate him with it until he—"

The air in the corridor instantly turned to ice.

A towering shadow detached itself from the alcove ahead. Damon.

Gina gasped and immediately dropped her gaze, shrinking back against the wall. Damon didn't even look at her. His storm-blue eyes were locked onto me, radiating a terrifying, suffocating darkness. He had heard Grayson's name on my lips.

"You have a very short memory, Isabella," Damon said, his voice a lethal, velvet rasp that made my pulse hammer in my throat.

I swallowed hard, my mind racing. The Plaza Hotel. The fountain. "The... the library," I stammered, heat rushing to my cheeks as I realized I had completely ignored my debt to him. "I apologize, Uncle. I can come tomorrow—"

"Tomorrow," he cut me off, his tone carrying the absolute, crushing weight of a Don's Command. "Before sunset. 'The Nest'."

He didn't wait for an answer. He turned and disappeared down the hall, leaving me trembling in his wake. I thought he was furious about my broken promise. I had no idea it was the mention of his nephew that had darkened his eyes.

By late afternoon the next day, the cavernous library of 'The Nest' was bathed in the dying, golden light of the setting sun. The scent of aged leather, whiskey, and Damon’s cedar cologne was intoxicatingly thick.

I had spent hours sorting through towering stacks of first editions. My muscles still screamed from the push-ups in the mud, and the quiet isolation of the penthouse finally broke my defenses. I rested my head on the cool mahogany of his massive desk, just for a moment.

The darkness pulled me under.

I didn't know how much time had passed when the scent of Cuban cigars pulled me back to the surface. The air was heavy, charged with a familiar, terrifying electricity.

I slowly opened my eyes. The sun had dipped below the skyline, casting the room in deep shadows. Damon was sitting in the leather chair beside me. He was perfectly still, his broad shoulders relaxed, his gaze tracing the line of my cheek with a strange, quiet intensity I had never seen before.

My mind was thick with sleep. The shadows, the desk, his overwhelming presence—it all blurred seamlessly into the dream I’d had nights ago. The dream where he had pinned me to this very wood, his lips bruising mine with dark obsession.

A flush of heat swept through my body. Half-asleep and entirely defenseless against the phantom memory of his touch, I let out a soft, breathless murmur.

"Stop it..."

The words hung in the quiet room, fragile and intimate.

Damon’s entire body went rigid. The fleeting warmth in his eyes vanished, instantly replaced by a Siberian winter. The air in the room seemed to freeze, snapping my mind fully awake.

He leaned forward, his jaw clenched so tight a muscle feathered in his cheek. The sheer violence radiating from him pinned me to the chair.

"Who are you talking to, *piccola*?" (little one) he asked, his voice a terrifying, glacial whisper.

"I-I wasn't," I stammered, my heart hammering against my ribs like a trapped bird beneath his predatory gaze. "It was just a dream."

Damon didn't believe me. The muscle in his jaw feathered again, his storm-blue eyes darkening into a terrifying abyss of possessive rage. He thought I was dreaming of Grayson. He thought I was pining for the boy who had left me to drown.

His hand shot out, his long fingers wrapping around my upper arm with bruising, absolute force. He hauled me out of the leather chair, dragging me past the mahogany desk and toward a heavy steel door concealed behind a bookshelf. The sheer, suffocating dominance rolling off him left me entirely paralyzed.

"Uncle, please-"

He shoved the door open, pulling me into a narrow, soundproofed room. The air instantly turned sharp, reeking of cordite, gun oil, and cold metal. It was a private shooting range, a steel-walled vault of violence hidden right inside his penthouse.

Damon snatched a heavy Colt M1911 from the metal counter and shoved it into my trembling hands. Before I could drop the weapon, his massive frame boxed me in. He stepped flush against my back, his broad chest a cage of burning heat against my shivering spine. I was entirely swallowed by his shadow.

"Your aim is pathetic," he murmured, his voice a lethal, velvet rasp that scraped against my nerve endings. His large hands completely devoured mine, his rough calluses scraping against my soft skin as he forced my arms up, locking my elbows into position.

I couldn't breathe. I was drowning in the scent of his cedar cologne and the raw, dangerous power radiating from him.

"Shoot," Damon commanded, his thumb pressing down hard on the nape of my neck, sending a violent shiver straight to my core. "Imagine the center of that target is his face. Now, blow his name out of your fucking head."

He squeezed my finger over the trigger. The deafening crack of the gunshot shattered the silence, the heavy recoil sending a shockwave through my frail shoulders. But Damon's body absorbed the impact, holding me perfectly, terrifyingly still. I was trapped in his violent embrace, terrified of his wrath, yet my face burned with a shameful, undeniable heat that betrayed my own sanity.

An hour later, the armored Cadillac dropped me off at The Villa. My legs felt like lead as I stepped into the grand marble foyer. I caught my reflection in the gilded mirror above the console table and froze.

My hair was disheveled. My lips were slightly swollen from biting them in fear, and a distinct, angry red mark bloomed on the side of my neck where Damon's thumb had pressed too hard. It wasn't just a bruise; it was a brand.

"Good evening, Miss Rossi."

I spun around. Maria, Eleanor's personal maid, stood near the staircase, a dusting cloth in her hand. Her eyes darted directly to the mark on my neck. A sickeningly triumphant gleam flashed in her gaze before she quickly bowed her head, masking her smirk. The vipers were already circling.

The next morning, the storm broke.

I stood in the center of Henrietta's private sitting room, the scent of old books and dried lavender suffocating me. Eleanor paced the Persian rug, dabbing her dry eyes with a lace handkerchief.

"She is compromising the family!" Eleanor cried out, pointing an accusing finger at me. "Maria saw her returning from his penthouse looking... ruined. She is parading around with her own uncle, making a mockery of my son!"

Henrietta sat in her high-backed armchair, her face carved from stone. She slammed her silver rosary onto the antique table, the sharp clatter silencing Eleanor instantly.

"Control your son, Eleanor!" Henrietta snapped, her sharp eyes blazing with the authority of a true matriarch. "Grayson brought this chaos upon us! He provoked these whispers when he chose that Irish whore over his duty. He is challenging my authority, and you dare blame this girl?"

Eleanor paled, her mouth snapping shut.

From the corner of the room, Bridget Falcone stepped forward, her hands clasped in a picture of perfect, false concern.

"Mamma, please," Bridget said softly, playing the peacemaker while pouring gasoline on the fire. "Perhaps we are all overreacting to servant gossip. But to protect the Falcone honor from these vile whispers, there is only one solution. We must show the Five Families that our pact is unbreakable."

Henrietta narrowed her eyes. "Speak plainly, Bridget."

"Move the wedding forward," Bridget suggested, a sly smile touching her lips. "Do not wait for his graduation. Marry them next month."

The room plunged into a dead silence. My blood ran entirely cold.

Henrietta looked at me, then at Eleanor, her expression hardening into absolute resolve. "Bridget is right. The rumors end now. Grayson and Isabella will marry next month."
