The Divided States of America, 2121 A hundred years after the Great Infection Spread swept across countries and continents, barriers rose and borders closed. Nations isolated themselves in protective siloes as survivors faced starvation, disease and the daunting task of rebuilding. The United States was carved into three Territories, each ruled independently. Today, the three Societal Order leaders ration everything - clothing, food, energy - because demand drowns supply. To conserve resources, citizens are declared either day dwellers or night dwellers, essentially limiting their existence to 12 hours each day. Where you're born is where you stay. Until now. Everly Scott is preparing to graduate from her final year of schooling when she's chosen to serve on an inter-Territory delegation. As one of twelve delegates, she will help assess and recommend updates to the Alliance Agreement, which outlines trade and peace relations between the Territories. Everly embarks on the journey of a lifetime - crossing the Xone walls to learn about people and places that have always been well out of reach. It's the greatest opportunity she's ever had. And also the most dangerous one. Secrets lurk within each Territory and Everly's about to find out what happens to those who uncover them.
