Publisher's Summary

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.


What the Critics Say

"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." (The Washington Post)
"Superposition [has] a kind of 'Law and Order with quantum physics' vibe." (SF Signal)
"[An] engrossing and illuminating sci-fi thriller....This is the way sci-fi ought to be." (The Wall Street Journal)

Frankenstein for the modern age

Many of us Audible listeners are multi-taskers, right? Ever had one of those moments where an audiobook is so intensely interesting that you cannot multitask, but have to just sit and listen? This is one of those books.

I'm a science writer (non-fiction) and have been writing about physics for 20 years. I can say with confidence that this book attempts something extremely ambitious—and pulls it off. I can't imagine explaining quantum mechanics this thoroughly and this entertainingly, but Walton does it. It's the classic "scientists-take-things-too-far" theme found in Frankenstein and so much sci-fi since, but here the dangers come from contact with parallel universes.

Whether you have a background in science or not, this is a thrilling murder mystery, and I highly recommend it.

Superb Superposition!

I cannot exclaim vociferously enough how compelling, creative and crazy this story is! I didn't know what to expect, but couldn't have imagined what I got.

The combination of mind-blowing quantum physics, paired with human frailty and a thrilling mystery topped off by a capital murder case isn't for the faint of heart. However, what could easily have descended to the maudlin was an acerbic, efficient conveyance of a plot as I've seen in a long while. At no point was I bored or wondering when it would be over.

The narrator stayed out of the way of the exposition so craftily that I often found myself wondering what I'd do if I were in the same situation-forgetting for long spells that this is fiction, and fantastic fiction at that.

Kudos for melding a marvelous message, with an outstanding orator for a superb Superposition. Highly recommended for anyone breathing!
