*Librarian Note: This is an alternate cover edition of asin B006OTGEX8There is a place in the sky where there are no stars, no matter how deeply the astronomers gaze into it. Atop a lonely mountain stands a mighty telescope that turns towards the coordinates of this abyss nightly, as if drawn to it. Receiving its commands from a computer that hasn't existed for twenty years. Introverted network engineer Shaw is brought in to find out why. All too soon he finds that while the night sky may be dark, it is not silent. A signal is coming from those coordinates. Creating a sound liquid and hypnotic with layers of data that suggest anything but randomness. A siren's song that leads to horrific suicides in everyone who listens to it. By the time Shaw realizes this, it's too late to stop the signal he sent back into the night. A signal obviously received, for the abyss has begun to move. And it's moving towards us.
