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.

Story
Robots are building a colossal telescope on the far side of the moon, with just two people supervising its completion. After a minor incident, these scientists become aware of an obstacle in the lunar soil. It's located outside the area reserved for the hypertelescope and is therefore none of their business. But their curiosity gets the better of them. The artifact seems to have properties that completely defy physics as they know it.

Deep in Antarctica, two researchers find an enigmatic black sphere suspended in the heart of a huge crater. Neither man is ever seen again. Decades later, reality fractures. A Manhattan skyscraper vanishes into thin air. An airplane crashes in the Sahara Desert—its existence defying logic. Across the globe, breathtaking technology and mysterious artifacts appear, all leading to one chilling truth: a parallel Earth is breaching the boundary between realities.

Story
Physicist Philip Moray is having a good day. He’s chipping away at his big work project. The lunch in the cafeteria is at least edible. And he’s looking forward to his end-of-the-day drink and a soak in the hot tub. Then, a strange device turns up in his office. A piece of technology he has never seen before–and shouldn’t even exist. Suddenly, corpses start turning up, eco-activists go on the attack, random people suffer bizarre symptoms. And every time the authorities get a lead, it traces right back to Philip and his colleague, Celia Hunt.

Story
Our universe is ruled by physics, and faster-than-light travel is not possible - until the discovery of The Flow, an extradimensional field we can access at certain points in space-time that transports us to other worlds, around other stars. Humanity flows away from Earth, into space, and in time forgets our home world and creates a new empire, the Interdependency, whose ethos requires that no one human outpost can survive without the others. It's a hedge against interstellar war - and a system of control for the rulers of the empire.

Jazz Bashara is a criminal. Well, sort of. Life on Artemis, the first and only city on the moon, is tough if you're not a rich tourist or an eccentric billionaire. So smuggling in the occasional harmless bit of contraband barely counts, right? Not when you've got debts to pay and your job as a porter barely covers the rent. Everything changes when Jazz sees the chance to commit the perfect crime, with a reward too lucrative to turn down.
