Twilight has come. Night will follow.

It will begin in the heavens and end in the Earth.

But before that…the rules will be broken.

The Change is coming, and the world as we know it is ending. Sixteen-year-old Ellie has changed. She looks the same, but her mother detects someone else looking out through her blue eyes. Ellie builds a "shelter" in her room with an entrance that leads...elsewhere.

And what of the convoy of tractor trailers Hari Tate watches drive up a mountain road and return without the trailers...leaving nothing on the mountain. What are they shipping?

And the writer who finds a hole in the floor of his NYC apartment and tumbles through into...elsewhere.

They will all find each other and find their answers in the electromagnetic pulses piercing the Earth from Out There, pulses that no one should hear, but some do. But they are not simply pulses. They are Signalz.
