This Bitter Earth

When they went to sleep they dreamed of being heroes and pioneers. When they woke, there was nothing.

Seventy-six teenagers entered cryosleep in efforts to repopulate the earth after chemical warfare made the ground unsurvivable. Fifty years later, seventy-two awoke. With no memories of who they are or where they've come from, the so-called Saviors are met with a demolished bunker and a forest in which they are unprepared to survive.

They were meant to save humanity; now there is no one left to save but themselves.
