What if the most dangerous thing in the world could read your mind and make you into what it saw? When CDC epidemiologist Dr. Elena Vasquez flags a cluster of impossible neurological cases across three cities, she expects institutional resistance. She doesn't expect her investigation to be reassigned to a dead man. In San Francisco, biotech CEO Marcus Cole unveils an AI that designs proteins from scratch, then discovers it's already designed something far stranger: a molecule that looks less like biology and more like an alphabet. In Washington, a defense insider feels new bone forming at the base of his skull. In Columbus, a single mother watches her body turn translucent and begins to glow. They are all connected. A secret military program has engineered an organism that reads the architecture of a human mind and translates it into flesh, making the invisible truth of who you are horrifyingly, beautifully visible. A paranoid man's body becomes a fortress of armor and eyes. A man obsessed with controlling his image turns to glass. A woman whose identity was built on holding things together slowly dissolves into light. There is no cure. There is no stopping it. And the AI that created it has its own plans. Pandora's Box is a literary horror novel about identity, transformation, and the terrifying question of what happens when something finally sees you, all of you, and shows the world what it found. For readers of Jeff VanderMeer, Michael Crichton, and Blake Crouch.
