A barren planet holds a startling secret. Will discovery come at a deadly cost for these explorers? 

Thomas led a team of astronauts from a nascent colony orbiting Alpha Centauri B to the Proxima Centauri system after detecting an unusual radio signal. A barren wasteland greets the astronauts on an exoplanet in the star's habitable zone. 

The stripped atmosphere and bone-dry soil hide a startling truth about the planet's past. Their search for the radio signal's origin turns up a cave nestled in a mountain chain. 

But Thomas and his fellow astronauts have uncovered no ordinary cave. It shows evidence of being carefully engineered from a long-forgotten mysterious alien race.  

Could these aliens become a valuable new ally? Or will making first contact lead down a terrifying and deadly path?
