Superposition

A QUANTUM PHYSICS MURDER MYSTERY.
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.

David Walton is the author of Quintessence (Tor Books, 2013) and the Philip K. Dick award-winning novel Terminal Mind. He lives near Philadelphia with his wife, seven children, and three hamsters. By day, he works on classified defense technology, which not even the hamsters are allowed to know about. David’s fiction explores themes that skirt the edges of science and religion, such as human origins, the nature of truth, the certainty of death, and the nature of the soul.

Praise for Superposition



“An expanding universe of delight….At its heart, the story is a standard variation on the mad scientist taking his experiments a step too far, but that worn format gets an electron-charged update in Walton’s hands.”

—Washington Post



“Gripping, suspenseful and original, this is a page-turning novel that readers are sure to devour.”

—RT Book Reviews



“A truly fascinating approach to thriller writing.… The story’s strength lies in its ingenious structure that neatly unfolds against an impressive backdrop of science.”
