A riveting crime novel with a speculative edge about the ways our perceptions of reality can be manipulated. Seven years ago, everyone in the world went blind in a matter of months. Technology helped people adjust to the new normal, creating a device that approximates vision, downloading visual data directly to people's brains. But what happens when someone finds a way to hack it and change what people see? Homicide detective Mark Owens has been on the force since before The Blinding. When a scientist is murdered, and the only witness insists the killer was blacked out of her vision, Owens doesn't believe her-until a similar murder happens in front of him. With suspects ranging from tech billionaires to anti-modernity cultists-and with the bodies piling up-Owens must conduct an investigation in which he can't even trust his own eyes. Thomas Mullen, the acclaimed author of Darktown and The Last Town on Earth, delivers an unputdownable crime novel about one man's search for truth in a world of surveillance and disinformation that's all too recognizable.
