The Vault

Post Apocalyptic fiction in a world nearly destroyed by nature. After the asteroid hit and the world was plunged into terrible winter not seen since the death of the dinosaurs, only a few select safeholds remained. Buried deep underground, the privileged chosen survivors waited until the fires were doused by the rains, and then the acid in the sky was washed out. A year later, when the rains ended, the best that America had left was sent out to find out what was left.
The world, they discovered, had changed. Rubble and ruin remained, but nothing lived. The trees were burnt and drowned. Landscape changed by mudslides and unimaginable weather. The planet was barren. Trees and grass burned up and washed away. Yet life is stubborn, even in the face of extinction. If the survivors can only find one sign of life, one survivor, one reason to hope then perhaps humanity can rise again.
Rebuild what it lost. Prove that they can overcome the failures of the past and become better than ever they were. But only if they can do it before something else kills them first.
