The mountain was their shield. Now it's a tomb.
The Vipers are coming, and Hardin Creek won't survive another assault. Frost Hellebuyck and Burgundy Mackenzie have one desperate play: dynamite the mountain pass, bring down a wall of limestone and shale, and seal the valley before the raiders reach them. But explosions don't care about who's on the wrong side when the rock starts to fall, and Cormac Mackenzie might be exactly that.
Trapped in a Ranger's tower with his companion Daisy and a newborn baby, Cormac is pinned down by a sniper who has turned the surrounding forest into a kill zone. Miles away, Auburn and the Furies-three women forged in fire-must outwit military patrols and break free from a government detention facility before what little hope remains runs out. Inside the walls of the commune, Mycosis-A spreads through the blood of the weary, but someone already inside is far more lethal than any raider at the gate.
They blew up a mountain to keep the monsters out, but the most dangerous predator is already among them. When the storm breaks, the Mackenzies will learn that survival and safety are never the same thing, and that some threats can't be stopped with an avalanche.
