Sovereign of the Abyssal Deep

Two hundred years of colonising an ocean world. And nobody ever thought to ask what lived below.

Commander Aria Voss commands the UTS Sovereign — the last of the great surface battleships, three hundred and eighty metres of railguns and nuclear-thermal drives patrolling the endless ocean of Thalassa. Her orders are simple: observe, record, protect.

Then a research vessel burns.

When fifty-three bio-armoured behemoths rise from the Meridian Trench and line up across her bow, Aria has seconds to decide: open fire, or listen. She chooses to listen. And what she hears will change everything.

Below the thermocline, in the dark that no human has ever directly seen, there is a city three million years old. There is a civilisation of ten million beings who have watched humanity build above them and said nothing — until now. And at the deepest point of the Trench, there is something far older still: a living archive encoding every species that ever existed on this world, six million years of life preserved in the dark.

Admiral Hargrove is loading his missiles.

Aria has forty-eight hours.

SOVEREIGN OF THE ABYSSAL DEEP is a propulsive military science fiction novel about first contact, the ethics of warfare, and the choices that define not just individuals — but civilisations. Perfect for fans of The Expanse, Old Man's War, and Dark Matter.
