What is The Closed Tunnel About

The main character of this new sci-fi book series, 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...

"I’m shocked! Wait, was all that for real?" Frank Schoonbaert, Media Magnat Holdings
