Five years after a devastating solar storm wipes out civilization and spawns a strange race of mutants, Rachel Wheeler and her misfit family must choose whether to hide away or fight to join other survivors.  As their food supply dwindles inside their bunker, radiation from abandoned nuclear plants is altering the world around them. Not only are the mutants building their own cities and weapons, the remaining dregs of the US military are massing for an attack. In this decaying environment, hostile new creatures crawl out from the crevices and up from the waterways to threaten them all.  But as a half-mutant, Rachel’s choice isn’t as simple as mere survival – the mutant way of life might be more promising than anything humans could hope to restore. And Rachel’s next decision could tear apart her family and the entire world.

Two childhood friends. An abandoned cabin in the woods. A lazy weekend reminiscing together. It was supposed to bring them closer together; to provide healing for their broken friendship.
