A routine patrol becomes humanity’s first contact with the impossible.

When Commander Jack Reynolds and the crew of the USS Colorado detect an unidentified object moving through the deepest regions of the Pacific Ocean, they assume it is a foreign submarine. What they discover instead will challenge everything humanity believes about its place in the universe.

The mysterious object leads to a shocking revelation hidden beneath the Mariana Trench—an ancient civilization that has remained concealed beneath Earth’s oceans for millions of years. As governments race to understand the discovery, a far greater threat emerges from the darkness between the stars.

A relentless cosmic hunter is approaching Earth.

As the countdown to extinction begins, Jack Reynolds finds himself at the center of a mystery older than human civilization itself. Ancient secrets, impossible technology, and a hidden purpose buried within Earth collide in a desperate struggle for survival.

What follows is a breathtaking journey from the depths of the Pacific Ocean to the farthest reaches of the galaxy, where humanity must confront the greatest question of all:

What if Earth was never an ordinary planet?
