SAS veteran Maric is training a special force team in suburban recon in Petersburg, Virginia. He meets a woman who is part of a Richmond Tactical team taking down a criminal syndicate. Days later a worldwide series of earthquakes and tsunamis knocks civilisation back to the horse and cart days, and she joins his team.
Maric's boss Cal sends him to the Atlas Mountains, on the edge of the Sahara Desert, to look into a strange happening recorded 80 years ago. It might explain what's been happening in the world today. Then a bombardment from the skies takes out the military bases and industrial capacity of the advanced nations.
The only functioning military capacity left on the planet is a handful of special forces scattered across the globe. Between them, Cal and Maric struggle to make sense of the devastating events besetting their world, and turn the tables on the alien perpetrators.
