The world has fallen to ash. 

After the murder of her father, Heidi Silverton has been left alone, in a society that has collapsed around her. All that was once good in the world has washed away in a tide of nuclear fallout, leaving behind nothing but the worst aspects of ourselves. Isolated from any other survivors, Heidi must struggle to find the one thing that her father may have left behind for her to cling to. 

Hope.
