The Rule of Three: Will to Survive

The Rule of Three series concludes with the lights turning on along the highway. I wonder how this could actually happen. Wouldn't the grid be significantly beat up in the process of the chaos that had ensued? I'd be interested in reading further exploration of the "reconnection" of society. What happens to old property? There was so much looting and mass chaos in the few months that it would be nearly impossible to make everyone whole gain. How many sections of society would just decide to live in their new structure rather than try to go back? What would become of money, companies, and all the structures of society?
The book doesn't explore any of the future. Instead, it focuses on the building up of a community and a coming of age of the main teenage characters. The youth become a more important part of the community and start to become primary decision makers in key areas. However, they also have to remember to support the people around them along with their own health. There is plenty of suspense and drama as they interact with other communities. (However, some seems a little manufactured. The writing makes it obvious that one encounter is friendly, while the characters are going paranoid over the the possible hostilities.) In the end, the torch is passed and the lights come back on.
