Ashes to Atom: the Dust Remains - Ashes to Atom, #1

Growing up a hundred years after the bombs dropped, James and Lucy hadn't ever known a world without slavery and lack. Until they met a man who could reunite the wasteland, make the world safe and free. Now the twins have a choice; to continue scraping by on whatever the old days had left for them, or make it brand new with him. Thing is, an awful lot of people don't want life to change. Nothing ever comes without being earned.
