My wife had 27 broken bones, a fractured skull, and barely survived—but when my billionaire mother-in-law told me I was just a disposable soldier, she had no idea who she had just declared war on...

The sinking of *The Obsidian Queen* should have been the end.

Federal authorities pulled sixteen high-value international criminals from the frigid waters of Boston Harbor. The stolen Pentagon data was recovered. But Victoria Vance had slipped into the black water during the helicopter explosion, using a hidden emergency submersible sled tethered to the yacht’s hull.

Two days later, our intelligence tracked her beacon to its final redoubt: The Monolith.

It was an old Cold War fallout bunker built into the sheer granite cliffs of Mount Desert Island in northern Maine, originally bought by Catherine Vance under an untraceable shell corporation in 1984. It was Victoria’s primary command hub.

Outside the bunker’s blast doors, fifty elite operators from the Black Dagger unit stood ready in the freezing rain, heavily armored, weapons locked and loaded.

Rosalie stood beside me in the tactical command truck, wearing a Kevlar vest over her dark sweater. She refused to sit in a safehouse anymore. This was her family’s poison, and she was going to witness the cure.

"Thermobaric breaching charges are set on the main vault door, Captain," Bishop reported, his eyes grim beneath his night-vision mount. "Inside, we have heat signatures for at least fifteen dead-ender mercenaries. Victoria is in the central communications bunker."

"No quarter for active combatants," I commanded. "Blow the doors."

The night exploded into blinding light.

The two-ton reinforced steel blast doors were blasted off their tracks by four shaped charges, collapsing inward with an earth-shaking crash that rattled the granite mountain.

"Breach and clear!"

We moved in.

The interior was a labyrinth of concrete corridors illuminated by flickering red emergency lights. Victoria’s remaining mercenaries opened fire with belt-fed machine guns from fortified sandbag bunkers, but the Black Dagger team moved with mechanized brutality.

Flashbangs disoriented the defenders; precise double-taps cleared the hallways. I moved at the point of the spear, my rifle firing in controlled bursts, dropping two shooters who tried to ambush us from a side armory.

Rosalie stayed tight in the center of the formation, her eyes scanning the corners, feeding tactical updates from Catherine’s original architectural blueprints on her tablet.

"Alexander! Left corridor leads to the main server vault!" Rosalie called out over the gunfire. "The blast door override is behind the backup generator!"

We turned the corner just as the final heavy blast door began sliding shut, thick steel teeth groaning as hydraulic pistons pushed it down.

I lunged forward, sliding beneath the closing door, firing upward to destroy the hydraulic control box. The door seized with a deafening screech, suspended three feet off the floor.

"Move through!" I yelled.
