A Mind-Bending, Near-Future, Science Fiction Technothriller.

Jacob Kelley's family is turned upside down when an old friend turns up, waving a gun and babbling about an alien quantum intelligence. The mystery deepens when the friend is found dead in an underground bunker…apparently murdered the night he appeared at Jacob's house. Jacob is arrested for the murder and put on trial.

As the details of the crime slowly come to light, the weave of reality becomes ever more tangled, twisted by a miraculous new technology and a quantum creature unconstrained by the normal limits of space and matter. With the help of his daughter, Alessandra, Jacob must find the true murderer before the creature destroys his family and everything he loves.
