Severance braces for a catastrophic impact as a colossal storm churns menacingly in the Atlantic. Eden, a seasoned storm investigator with a global reputation, feels a gnawing uneasy feeling in the pit of her stomach. Her extensive experience with unprecedented weather events tells her this could be a monstrous hurricane poised to strike. She comes together with friends, past and present, to determine the significance of the cyclone's track. They watch and pray, knowing the conditions are ripe for disaster.

The storm's spiritual implications and its impact on the violence that has come into Severance cannot be overlooked. There has been an uptick in supernational activity that has to be addressed. The friends understand the importance of seeking God's answers to direct their efforts and realize secrets hinder their progress. As some search their hearts to ensure nothing is hidden, it becomes apparent that someone is holding back.

Meanwhile, Captain Lucien grapples with a different kind of storm. A serial killer is terrorizing Severance. He called Alaster Soa, a leading expert in Criminal Psychology, to assist in the investigation. Together, they work to unravel the thread that ties the victims together and solve the mystery of the enigmatic black, gooey substance left behind. But the more they uncover, the more questions arise, leaving them with a perplexing puzzle.

Severance stands on the brink of a catastrophe. The storms rage simultaneously on land, air, and sea. Will the serial killer be identified before the hurricane unleashes its fury? Or will the town be forced to confront the devastating forces of nature and human evil simultaneously?
