Chapter 23 - The Cold Descent
The drop into the North Atlantic was a violent, skull-rattling transition from air to ice.
The ocean struck the titanium shell of the *Exo-Vanguard* like a concrete slab, dragging me beneath the foaming whitecap surface in an explosion of emerald-green bubbles. The muffled roar of the *Healy*’s diesel engines died out instantly, swallowed by the suffocating silence of the abyss.
"Telemetry green," Vance’s voice crackled through the ultra-low frequency umbilical wire attached to my hoist line. "Descent rate: three feet per second. Morgan, you have visual on the down-haul cable?"
"Cable in hand," I breathed. My voice sounded metallic inside the sealed helmet, accompanied only by the rhythmic, mechanical hiss of the carbon-dioxide scrubber cycle. "Passing two hundred feet. Ambient temp: twenty-nine degrees Fahrenheit. Thermocline boundary layer crossed."
The sunlight died completely at four hundred feet. The Atlantic turned to liquid charcoal, endless and crushing, pressing against the quartz dome with thousands of pounds of hydrostatic weight. Outside my viewport, strange bioluminescent organisms drifted past like ghosts—comb jellies flashing cold violet and blue, unbothered by the pressure that would liquefy a human ribcage in an instant.
At six hundred feet, my suit's twin high-intensity LED searchlights sliced into the gloom.
"Depth eight hundred," I reported, my breath fogging slightly against the corner of the faceplate before the internal heaters cleared it. "External hull pressure: three hundred and sixty PSI. Joints holding. Rotary seals are tight."
"Be advised, Morgan," Mendez broke in over the link. "Surface sonar reports the *Viper* shifted four inches three minutes ago. Hull creaking frequency has doubled. You don't have time for a scenic tour."
"Understood."
At one thousand feet, the ocean floor materialized out of the dark—a jagged, terrifying landscape of black volcanic basalt, covered in a thin dusting of prehistoric silt. And there, resting upon the edge of eternity, lay the USS *Viper*.
The nuclear attack submarine looked like a wounded leviathan. Her black anechoic rubber tiles were stripped away in massive swaths, revealing the polished HY-80 steel underneath. Her nose was wedged hard into a jagged crevasse in the rock, but her entire rear half—the sail, the reactor compartment, the shrouded propulsor—hung precariously over an abyssal drop that plunged into absolute void.
Streams of tiny bubbles hissed continuously from her engine room vents.
"I have visual on the target," I whispered, the sheer scale of the disaster stealing the breath from my lungs. "My God... she’s balanced on a knife’s edge. If the basalt gives way, she’ll tumble straight down into the trench."
"Move to the forward escape trunk," Vance ordered, tension straining his every syllable. "Locate the external high-pressure salvage blow valve. It’s marked 'AIR HOSE CONNECTION — COMPARTMENT FORWARD'."
I hit the quick-release on the surface down-haul cable, activating the suit’s dual thruster pack mounted on my hips. The electric micro-props whirred, pushing my eight-hundred-pound armored frame through the icy current toward the rounded nose of the submarine.
My armored boots landed on the slippery curved casing of the *Viper* with a heavy, hollow *thud*.
Immediately, from deep within the belly of the ship beneath my feet, came a sound that made my marrow run cold: three distinct, desperate thumps against the steel hull.
*Clang. Clang. Clang.*

They knew someone was on the hull. One hundred and thirty-two men and women, freezing in the dark, breathing air that was rapidly filling with deadly carbon dioxide, listening to the footsteps of someone they couldn't see.
"Hang on," I muttered toward the steel plates beneath my boots. "I’m here."
