Beneath the oceans, a war is quietly unfolding - a battle over the pipelines and digital cables that carry the oil, gas and data modern life depends on. These invisible networks, stretching across the globe, are vital, and increasingly under threat. We must pay attention, before it's too late.

In The Undersea War, award-winning journalist Elisabeth Braw exposes the frontlines of this hidden conflict.

Minute by minute, hour by hour, she recounts incidents with nail-biting suspense: mysterious damage to undersea cables, shadowy ships loitering near pipelines and the growing realization that these vital arteries may be deliberately targeted.

From Arctic ice to tropical seas, ordinary people - from islanders cut off from the digital world to officials confronting suspicious foreign vessels - feel the consequences of a conflict most of the world does not even know exists.

Drawing on deep reporting and exclusive interviews with ship captains and crews, witnesses, policymakers and executives, Braw moves across continents and oceans - from the Arctic waters of Svalbard to the Baltic Sea, from the Matsu Islands off Taiwan to England, Denmark, Tanzania, Indonesia, and beyond - revealing a globe-spanning struggle for control beneath the waves.

Urgent and immersive, The Undersea War is a gripping, international investigation into an invisible conflict that could determine who controls the world's future.
