At twenty-four, my stepmother tried to trade me to one of her wealthy business partners to save her company—and when I escaped through a bathroom window, barefoot and bleeding, the people she sent after me were already closing in. Then a black car appeared through the storm, and I threw myself in front of it, never imagining the stranger inside might be even more powerful than the family I was running from.

"Don't move," Adrian whispered instantly.

The tender intensity vanished, replaced in a microsecond by lethal combat precision. He reached behind his back, drawing a suppressed 9mm Sig Sauer from his waistband holster. He pushed me gently behind the heavy steel frame of the open vault door.

"Stay down. Do not come out until I tell you," he ordered in a breath so low it was almost silent.

Footsteps descended the wooden stairs—slow, deliberate, masked by the rhythmic pounding of the rain against the ground-level windows.

"We know you're down here, Cross!" a voice echoed through the basement.

It was Marcus Vance.

"Celeste’s bail was posted an hour ago by an offshore syndicate," Marcus continued, his voice calm, professional, detached. "Victor wants the hard drives, and he wants the girl. You give us the drives, Cross, and you walk out of here alive. Halden Group is dead anyway."

Adrian didn't answer. He clicked off the work lamps with a remote trigger in his palm, plunging the cellar into total, pitch-black darkness.

The silence was absolute, broken only by the hum of the dehumidifier and the distant rumble of thunder.

*Crack.*

A flashlight beam cut through the dark, illuminating the wine racks. Marcus was flanked by two men in tactical vests, their weapons raised.

Adrian fired twice through the wooden slats.

The suppressed coughs of the Sig Sauer were muffled, followed immediately by the heavy thud of a body hitting the stone floor. One of the guards collapsed without a sound.

"Return fire!" Marcus screamed, opening up with an automatic submachine gun.

A hail of 9mm rounds shredded the antique oak cabinetry, splintering wood and shattering hundreds of vintage wine bottles. The smell of copper, spilled merlot, and cordite filled the air like a butcher shop.

I pressed my back against the cold steel inside the vault, my heart hammering against my sternum.

My eyes darted across the floor of the vault. Mounted on the interior wall was the central security hub for the Greenwich estate—an older model analog relay that my father had installed twenty years ago.

*The fire suppression system.*

Halden Group specialized in subsea and industrial engineering. My father’s private vault was protected by a high-density carbon-dioxide fire suppression system designed to smother electrical fires in four seconds flat.

I looked at the red manual pull-handle behind a break-glass cover.

I reached into my pocket, pulled out the heavy brass key to the desk drawers, and smashed the glass.

Adrian fired three more rounds, forcing Marcus behind a concrete support pillar.

"Adrian!" I screamed over the gunfire. "Vault! NOW!"

Adrian didn't hesitate. He broke into a sprint, sliding across the blood-slicked stone floor and diving through the vault doorway just as Marcus leaned out to fire a burst.

I grabbed the heavy vault door and threw my entire body weight against it. Adrian scrambled to his feet, catching the steel wheel, his muscles straining as we slammed the multi-ton door shut. The heavy locking bolts engaged with a deafening *clack-clack-clack*.

Through the four-inch bulletproof observation port in the door, Marcus Vance appeared, his face twisted in rage as he hammered the butt of his weapon against the glass.

I looked him dead in the eye and pulled the red suppression handle down.

Outside the vault, in the basement archive, high-pressure industrial nozzles erupted with a deafening hiss. Thousands of cubic feet of pure carbon dioxide flooded the room, instantly displacing every molecule of oxygen.

Marcus dropped his gun. His hands flew to his throat, his eyes bulging as he gasped for air that didn't exist. Within twelve seconds, his knees buckled, and he collapsed against the glass, sliding down onto the concrete floor into unconsciousness.

Inside the vault, Adrian and I stood in the dim emergency light, chests heaving, breathing the filtered air of the sealed chamber.

Adrian turned to me, his gun lowered, his eyes wide with an emotion that was raw, ferocious, and completely unfiltered.

"You just gassed three tactical operators with an antique fire extinguisher," he breathed.

"I told you," I gasped, leaning back against the steel wall, a wild, breathless laugh escaping my lips. "I'm an accountant. I know how to balance the room."

Adrian dropped his weapon onto the desk. He took two long strides, closed the distance between us, and grabbed my face in both of his hands.

He kissed me.

It wasn't gentle. It was a fierce, consuming collision of relief, adrenaline, and undeniable hunger. I wrapped my arms around his neck, pulling him down, tasting the salt of rain on his skin and the heat of his mouth. Every terror of the last forty-eight hours burned away in the furnace of his embrace.

When he finally pulled back, his forehead resting against mine, his gray eyes were ablaze.

"Tomorrow night is the Metropolitan Financial Gala," he whispered against my lips. "Every camera in New York will be there. Celeste and Victor think they're meeting their foreign buyers to liquidate the subsea patents."

"Let them go," I whispered back, my fingers tracing the hard line of his jaw. "Let them walk right onto the stage."

"And then?" Adrian asked, his mouth curving into that devastating, wicked smile.
