Thirty years after two explosions at Chernobyl Nuclear Power Plant left the entire continent of Europe uninhabitable, the world is grappling with the shattering legacy of "Exodus" ? especially the former United States of America, now divided by the forbidding Midamerican Wall. But when a mysterious particle nicknamed "Spore" emerges in the European Exclusion Zone, it spurs a global crisis that changes the lives of troubled ex-Marine and single mother Jack Martin, social media impresario Lennox Lang, President of the Democratic States of America Teresa Spencer, young historian Yasmin Mira Khan, and MIT physics student Adam Hynek. Each must reckon with the shocking revelation of Spore's true abilities, and the dark and powerful forces who will stop at nothing to claim it. The adventure will lead them to the limits of their universe? and beyond it.
