They say that necessity is the mother of all inventions. Amir Weatherby has the world in his hands, quite literally. When his company discovers an asteroid on a direct collision course with Earth, they decide to keep the news quiet and find a way to survive the impending apocalypse themselves. Secret projects begin with the intent of preventing the world going the same way as the dinosaurs. Three top-secret sites are developed, each designed to hold a small pocket of the human race safe until after impact. It just so happens that one of these sites is in space. The former ISS is transformed intoa safe haven called the ARC, the Automated Resettlement and Repopulation Cryostation, where some of the world’s greatest scientific minds will sleep through the whole show. But events unfold in ways that couldn’t have been predicted, and when they arrive back on Earth there is a whole new disaster waiting for them.

Their plans to survive the end of humanity were meticulous. Thorough. Flawed. They landed back on Earth hundreds of years after their expected return, and now the planet they once called home is unrecognisable. Warring tribes threaten their very survival and members of Sierra team and Dr. David Anderson must work with their now-sentient AI to find a way to live peacefully with the survivors of the African facility. But a greater threat than the power struggle between humans presses in on them, and they must choose sides to protect themselves from the terrifying plague sweeping over the continent during darkness. They must find a way. They must survive The Swarm.

In the aftermath of The Swarm’s relentless assault, and the brief but bloody civil war, Anderson and the other survivors must find a way to secure their future in their new home. With tensions running high and the ever-present threat of the next moon phase, a plan is devised to take them to the source of the danger. To Europe. To ECHO site. But their journey is fraught with danger, and along the way they discover that nature has not been as dormant as first believed. Life outside the safety of their camp poses more of a risk than anyone could have imagined, threatening their survival and risking everything they have built so far.
