The world is broken. Can humanity survive its own rescue?

Tion, Earth’s last sanctuary, has fallen into mayhem. The global processing service that once controlled its ecosystem is gone, leaving billions of people paralysed by data withdrawal. Chaos reigns as the spheres encircling the planet descend into anarchy, and survival becomes a brutal fight for supplies and control.

Heikapu—a former cop who’s gone rogue—is in pursuit of a lost biotechnology that could potentially save humanity, though her true motives remain her own. But she’s not the only one searching. The Votaries, a growing army of zealots, will stop at nothing to claim the biotech for themselves. Meanwhile, in the shadows, another group wants to resurrect the processing service, believing it to be mankind’s only chance at stability.

Amid the madness, rumours of a being with the power to repair the broken world emerge. Some see it as a god, others as a threat. As desperation mounts, Heikapu must decide: Will she fight for survival—or freedom?

Rich with tension and thought-provoking questions, Demiurge is a gripping exploration of the human drive to create—and destroy. Fans of Children of Time and Blindsight will be spellbound by J.C. Gemmell’s third instalment in the Tion series, a dystopian page-turner that asks: What is the price of hope in a broken world?
