The Collapsing Empire

by John Scalzi

Published 21 March 2017

The Collapsing Empire is an exciting space opera from John Scalzi, the first in the award-winning Interdependency series.

Does the biggest threat lie within?

In the far future, humanity has left Earth to create a glorious empire. Now this interstellar network of worlds faces disaster – but can three individuals save their people?

The empire's outposts are utterly dependent on each other for resources, a safeguard against war, and a way its rulers can exert control. This relies on extra-dimensional pathways between the stars, connecting worlds. But 'The Flow' is changing course, which could plunge every colony into fatal isolation.

A scientist will risk his life to inform the empire's ruler. A scion of a Merchant House stumbles upon conspirators seeking power. And the new Empress of the Interdependency must battle lies, rebellion and treason. Yet as they work to save a civilization on the brink of collapse, others have very different plans . . .

The Consuming Fire

by John Scalzi

Published 16 October 2018

The Consuming Fire by John Scalzi is the dazzling follow-up to The Collapsing Empire, the second in the Interdependency series – a space opera in a universe on the brink of destruction.

The Interdependency, humanity’s interstellar empire, is on the verge of collapse. The Flow, the extra-dimensional pathway between the stars, is disappearing, leaving planets stranded. Billions of lives will be lost – unless desperate measures can be taken.

Emperox Grayland II, the leader of the Interdependency, is ready to take those measures. But it’s not that easy. There are those who believe the collapse of the Flow is a myth – or an opportunity for them to ascend to power.

While Grayland prepares for disaster, others prepare for civil war. A war that will take place in the halls of power, by the altars of worship and amongst the titans of industry as much as between spaceships. Nothing about this power struggle will be simple or easy . . . and all of human civilization is at stake.

by John Scalzi

Published 14 April 2020

The Last Emperox is the explosive conclusion to John Scalzi's Interdependency series.

Can they escape the end of an empire?

Entire star systems, and billions of people, are about to be stranded. The pathways that link the stars are collapsing faster than anyone expected, accelerating the fall of civilization. But though the evidence is insurmountable, many are in denial. And some even attempt to profit from the final days of this golden age.

Emperox Grayland II has wrested control of the empire from her enemies. But even as she works to save her people, others seek power. And they will make a final, desperate push to topple her from her throne. Grayland and her depleted allies must use every tool at their disposal to save themselves and humanity - yet it still may not be enough.

Will Grayland become the saviour of her civilization . . . or the last emperox to wear the crown?
