Out on February 4, 2025

Be prepared for the upcoming sci-fi sensation!

Ink & Cinema Official selection “Best first ten pages” 2023, USA.

What if we told you that 3,000 feet underground there's a network of high-tech cities connected by ancient tunnels? Yes, right now.

The main character of The Closed Tunnel, Tony from New York accepts a job from the strange head of a pharmaceutical company. It takes him first to the National Geophysical Research Lab on Long Island and then—unexpectedly!—underground. He finds himself in Luxor Ville, the city of the elite, and explores Hearton City with genius scientists presumed dead or missing on the Surface.


Meanwhile, in the ancient tunnels, the world's greatest physicists are conducting an unbelievable experiment that should redefine our understanding of the laws of the universe. They think they have it all figured out. But it's impossible to anticipate everything...


The Closed Tunnel weaves suspense, thrills, wow twists, an unpredictable ending, and a dash of spice into a tapestry of real facts, technology, and shadows of the supernatural.

Imagine having a golden ticket to the underworld of 2022. Are you ready? Then buckle up!

SOON - on June. 21st
