In this thrilling and utterly unique work of narrative non-fiction, Katherine Dunn explores the acute vulnerability of the GPS satellite system – in a book that lifts the lid on the invisible connections of the globe, from the space race to the phone in our pockets

This is the story of the Global Positioning System, the network of U.S. government satellites that encircle the earth: a vast web that, in a matter of decades, has transformed the way we understand space and time, making us critically dependent on vulnerable technology we often forget is even there.

It is a system that was conceived of as a military product designed for war, but which has since evolved into a vital everyday tool that tells us where we are and when at any given point. But its use doesn’t stop there: GPS has transformed our navigation systems and our global trade, our farms and our supermarkets, our stop lights, banking networks, and our energy systems. It overturned online dating, exercise regimens, travel planning and takeaways. It reshaped our daily lives, and then it transformed us. When GPS took away our familiarity with getting lost, it also stripped us of our ability to hide – turning our place in the world into a mappable, knowable entity, and put us, a blinking blue dot on a screen, at its centre.

In this thrilling, page-turning work of narrative non-fiction that touches on tech, geopolitics, international relations and economics – Katherine Dunn explores the acute vulnerability of an essential global system that touches all our lives. With echoes of Kleptopia, The Fifth Risk and Prisoners of Geography, as well as echoes of Islands of Abandonment by Cal Flynn and Entangled Life by Merlion Sheldrake in the way it exposes a hidden, esoteric system that we all rely on – this is a book that lifts the lid on the invisible connections of the globe, from the space race to the phone in our pockets.
