Deep End. Supernova EMP, #2

They'll either find salvation or face damnation. Screams of agony. Cries of terror. The sounds of a dying civilization echo all around Josh Standing as he navigates the aftermath of this new post-apocalyptic world. All traces of modern advancements have been wiped away by the supernova EMP when he washes ashore on the Georgia coast. Alone. And when a psychotic gang takes Josh prisoner, he's torn between grief and gratitude that his daughter isn't discovered nearby.
Josh swore long ago to serve and protect-and he desperately wants to help the other prisoners-but his daughter needs him, too. If she's still alive. Circumstances are only slightly better for Josh's wife Maxine and their cancer-stricken son as they settle at the family farm in West Virginia. There, they discover Maxine's beloved mother has been heavily effected with the aftereffects of the supernova, and her battle-hardened father struggling to keep the family together.
Even worse, a local militia is targeting the farm for its resources, which causes further dissention in the family over how to handle the attacks. When the dust from the firefights settle, the choice between duty and family will be the difference in who is left standing.
