When the Prometheus exploded, everything changed. The ship was meant to retrieve a team of colonists from Mars. Instead, it ushered in a decade of chaos and left the colonists stranded.

For all sixteen years of his life, Tom has known nothing but the red dirt of Mars and the cramped research base he calls home. That and stories of Earth, a silent blue dot in his sky. As the base's resources dwindle and tensions between the surviving colonists run high, Tom makes a promise to himself: he'll get to Earth or die trying.

Sophia Kasparov, daughter of the AI expert behind the Prometheus, triggers a global media frenzy when she accidentally reveals her father's plans to launch a rescue mission to Mars. Support for the controversial mission is hard to come by, especially when it's opposed by the ruthless anti-spaceflight eco-fundamentalist Cita Stone. As Sophia struggles to navigate the political chaos surrounding the mission, she uncovers a fifteen-year-old mystery that could change everything – the truth about the Prometheus disaster – and discovers that her father will risk everything for his plans, even her.
