About this listen

In the eternal darkness of the moon, something is calling.

When NASA's Sentinel I satellite detects an impossible reflection and a mysterious signal from Shackleton Crater, the world is thrown into chaos. The discovery points to one chilling truth: an alien artifact lies hidden beneath the lunar surface—and it wants to be found. As China scrambles to exploit the revelation, a new moon race ignites, pushing humanity to the brink.

Thrust into the center of the storm, NASA astronaut Charlie Reid must navigate a volatile mission where science, survival, and military might collide. With the fate of humanity hanging in the balance, the question remains: what will they find—and will we survive it?

The race for the future has begun. And the prize may cost us everything.
