Periodic East

It's been six years since First Contact was assumed to be made with another intellectual species, but everything known came to an end when The Blast occurred and the world entered Nuclear Winter. A young man named Tiberius reluctantly leads a small group of survivors through the New Ice Age and finds a human-like footprint in the snow, the first sign that their group is not alone in the Ice Jungle. Hundreds of miles above Earth, Icarus is a state-of-the-art satellite space station that shines like a burnt pixel in the tundra sky. Onboard, Sam is a Liaison facing his own demons when he finds himself simultaneously the only person in the space station and believes he has discovered a stowaway.
