Creatures of Phoenix

In 2093 all electronics on the planet were affected by a world wide solar emp that fried everything and killed millions with solar radiation. Those that were left were cut off from others and left in a barren wasteland similiar to a nuclear post apocalyptic world. Small communities survived simply because of unaffected dams and solar pannels which are only enough to power hot water heaters in the rich houses and the sector centers.
17 year old Cadence Camdyn and her 14 year old little sister Ally are all thats left of her family.
Cadence is a scavenger for their small settlement called Phoenix. Her job is to gather tech, supplies, and trinkets for the council who is incharge of Phoenix.
19 year old Xander Laforest is a genius who researches tech at Point Tech, (the tech sector) and is working to develope the electricity.
With no manuals and no teachers it is up to point Tech to rediscover the way out of the stoneage and as Xander proves how smart he is he realises that burdden falls to him.
When Cadence breaks the rules her and her sister are punished severly, now running on half rations Ally starves herself to feed their old neighbor next door. While on a forbidden hunting mission to feed her sister Cadence comes across a strange piece of tech in a rsstricted sector that is actually working she takes it to xander in secret hoping for a giant payday.
The tech turns out to be a flight recorder from a shuttle that tried to land in cape Canaveral. One that was too far away to be affected by the Surge.
Xander gets it to play and they find out that the solar emp that ended the world wasnt all that was going to happen. The earths climate had distabalized and the disenigration of the earths ozone layer would end all life if something called project greenland wasnt activated.
Something that could only be done in washington d.c. in a crisis bunker developed for the president. The problem? It required electricity.
And no one in phoenix would believe them.
