Zach Croft wants to forget the Prescott colony ever happened.

He wants to forget the crimson sand dunes, violent dust storms, and meteor impacts. He wants to forget the sight of his neighbors bleeding from their eyes as boils ravaged their bodies. He wants to forget the fact that his best friend was left to die.

Most of all, he wants to forget that, without Prescott, humanity is doomed.

But when a Prescott dropship plummets from the sky twenty-three years later, he has no choice but to remember.

As Zach embarks on a life-or-death quest for answers about the dropship’s impossible return, he discovers something even more important: there is still hope for humanity’s survival.

With conditions rapidly worsening on Earth, he is in a race against time to return to Mars, finish the work that Prescott started, and save the human race from extinction. To do so, he must face the truth about what really happened in Prescott—a truth that calls into question everything he thinks he knows about who he is, who he trusts, and what he has done.
