Surviving the collapse was just the beginning. The world didn't just go dark, it went lethal. For the Mackenzie clan of Hardin Creek, Kentucky, every new day brings fresh disaster, and the fragile alliances holding them together are fraying fast. Burgundy killed a man to protect her little sister, Poppy. Now she's paying for it, and the price may cost her everything. Under arrest in a world that has abandoned the rule of law, Burgundy struggles to hold the family together while her own uncle works against her at every turn. Hundreds of miles away, Auburn presses home half-blinded from an earthquake, protecting a pregnant friend from a danger she can feel but not name. And Cormac, shackled to a pair of volatile ex-cons he can't shake, is one wrong move from a body count nobody walks back from. Meanwhile, Frost Hellebuyck finds himself in the crosshairs of the town's most powerful man when the sheriff's own daughter shows up at his door begging for sanctuary. When an active shooter locks down the local hospital, survival becomes a math problem with no good answers. Trust the wrong person, and you don't see morning. In a world this broken, who you side with is the most dangerous bet you'll ever make...and not everyone is going to pick right.
