Eight hundred miles north of the burning cities, in the frozen wilderness of Michigan's Upper Peninsula, Ronnie Halvorsen watches the world end.
The bombs spared her shore. The electromagnetic pulse did not. Trucks die. Radios die. And as the long dark settles over a ruined country, Ronnie understands that survival now means something older and harder than she ever imagined.Because the bombs were only the beginning.
Something is rising out of the deep water. Pale things that walk on the frozen lake. Voices in the night that call your name in the tones of everyone you have ever lost. And they want one thing above all: Ronnie's sixteen-year-old nephew, Denny, a boy who was taken by the water as a child and given back, a key cut to fit a door at the bottom of the world.
To keep him alive, Ronnie must lead a handful of desperate survivors across a shore crawling with the dead, toward a truth her own family has guarded for a hundred years. The light holds them back. The dark is winning. And the sky is going out for good.
As a permanent winter smothers the last of the sun and a thing the size of a harbor drags itself toward the living, Ronnie will learn the one weapon that has ever beaten the water. Not fire. Not steel. Something smaller, and far harder to hold onto.
You get close. You stay loud. You never let anyone face the dark alone.
