When Earth intercepts a message from the outer reaches of the solar system, all eyes turn to Carmen Vincent and her companions on board the star runner to spearhead the investigation.
For a mysterious object is hurtling towards Earth.
Is it a spaceship, an asteroid, or the first wave of an attack?
Hours into the mission, Carmen discovers within the message a hidden fragmented code not meant for her.
Someone on her crew knows the secret about the code and is working to keep anyone from deciphering it.
What began as a simple operation turns into a fight for survival against the saboteur, and only Carmen and her allies stand a chance to stop what's coming before it's too late.
