In the crushing abyss of the Pacific, silence is not peace. It's a prelude to damnation.

Captain Ortega commands the USS Caspian, a state-of-the-art nuclear submarine and the apex of naval engineering. His mission is routine, his crew the best in the fleet. But when a sudden, inexplicable power failure plunges them into absolute darkness and silence, their training is put to the ultimate test. It's not a system malfunction; it's a suffocating, complete death of the machine.

Stranded miles beneath the surface, the crew's discipline begins to fray as impossible phenomena plague the ship. A single, metallic tink against the hull from the outside. A ghost signal from a submarine lost for over fifty years. An unnatural heat that begins to boil the very water around them.

Ortega and his crew quickly realize they are not adrift. They are caught.

They have been swallowed by an intelligence that defies physics and sanity—a living, breathing current with an appetite as old as the stars. Trapped inside a biological system of incomprehensible scale, the Caspian is no longer a hunter. It is prey being digested. As madness seeps through the steel hull and the crew turns on one another, Ortega must confront a truth more terrifying than any monster: their tomb is not just a place, but a living god. And it is always hungry.

A perfect storm of military sci-fi and Lovecraftian dread, this novella is a must-read for fans of Alastair Reynolds, Adrian Tchaikovsky, and the chilling cosmic horror of films like Event Horizon and Underwater.
