Epidemic

It has been forty years since America closed its borders and separated from the world following the Vietnam War. In the ensuing years, the country has developed in incredible ways, or at least, that is what Maxwell and Karina, a set of twins from a community deep in the forests of New England, have been told all their lives. In a town surrounded by larger than life trees and crags, they didn't have a reason to believe otherwise.
That belief is put to the test when they find their house ransacked, their mother missing, and their only chance to live is outside of the barriers they've grown used to. Barriers. that they never realized existed.
