Six months after being wrongfully accused of terrorism and hunted across Europe, software developer Samanta Di Vincenzo has rebuilt her life in Estonia, writing code for a Mars rover mission. 

Her dream job. A fresh start.

Then something impossible appears on the Martian surface. And when Sam discovers a hidden backdoor buried in the rover's software, the people she trusts most want her to stop asking questions.

With her girlfriend fleeing Europol, her family threatened by the Camorra, and a conspiracy tightening around her, Sam is dragged into a desperate race against time to expose a secret that could reshape humanity's future among the stars.
