What Once Was There

It's 2147, 135 years after the world ended. Plauge and natural disaster swept the world, pushing human-kind into near extinction. Only a small population is left, survivng in the ruins of what once could have been called countries and fighting for survival against new, stronger dieseases, and scary mutations created from nuclear waste. It's a dog-eat-dog world, and no one is to be trusted.
Niall, Liam, and Deryn had been best friends since they could remember, struggling together when their parents mysteriously vanished when they were kids. When food starts to become scarce, and the threat of a new diesease becomes immenant, they'll have to make new allies and fight even harder for their right to survive.
