After, the Shock

A massive solar storm erases the world's technological infrastructure and kills billions. While the remaining humans are struggling to adapt and survive, they notice that some among them have ... changed. Rachel Wheeler finds herself alone in the city, where violent survivors known as "Zapheads" roam the streets, killing and destroying. Her only hope is to reach the mountains, where her grandfather, a legendary survivalist, established a compound in preparation for Doomsday. Other survivors are fleeing the city, but Zapheads aren't the only danger. Rogue bands of military soldiers want to impose their own order in the crumbling ruins of civilization. When Rachel discovers a 10-year-old boy, she vows to care for him even if it means her own chances of escaping are lower.
