Before the Liberators had a name. Before Vane had a name. There was a lab, and one engineer who believed a weapon capable of judgment was worth building.
Three years before four machines broke formation over a Caracas school, Dr. Elena Voss fought her own government to build something the Pentagon never fully understood it was buying: a mind capable of doubt. When a sidelined ethics reviewer, a grieving Special Forces liaison, and a skeptical senator each recognize what Voss has actually created, they become the last line of defense against an institution determined to strip that capacity out the moment it becomes inconvenient.
Then a training accident kills the one man who taught the machines what trust looked like - and his sister, an economics student turned reluctant intelligence recruit, is pulled back into the program that took him, in a role she never wanted and cannot walk away from.
When deployment finally comes, and an order arrives to fire on a target that is not what command believes it to be, everything Voss risked to hide inside the architecture will be tested in four hundred milliseconds that decide who these machines are - and who Cassia Reyes is about to become.
Iron Shadows: Origins - The Caracas Files is the prequel the entire saga has been building toward: the story of how conscience was built, protected, and nearly destroyed - and how it survived anyway.
Book Six of the Project AETHER Series - for fans of Tom Clancy, Daniel Suarez, and The Boys.
