Euclidean's hidden technologies are out in the world, for anyone to use. How long until their darker secrets join them?

Detective Cassie Kinsala has accepted her place in their secret world, just as the barriers between it and the real world fail. But with her superiors finding it harder to avoid the truth, Cassie is drawn into the politics of a department in panic – potentially more treacherous than any gunfight.

Everyone is caught up in the wake of the changes: government and corporate interests trying to control or suppress the new technology; a movement of independent inventors embracing and innovating; and someone using the technology for increasingly brazen crimes.

As the focus of all this newness, the city grows volatile with all the new tech, and more dangerous secrets lurking not far behind.
