The Arthur C. Clarke award-winning author of Children of Time brings us the third and final novel in an extraordinary space opera trilogy about humanity on the brink of extinction, and how one man's discovery will save or destroy us all.

'What I’ll remember most is how [Adrian Tchaikovsky] crafted the perfect emotional resolution to this intellectually intricate tale that left me in tears and has stayed with me since.' -Polygon

Idris Telemmier has uncovered a secret that changes everything—the Architects’ greatest weakness. A shadowy Cartel scrambles to turn his discovery into a weapon against these alien destroyers of worlds. But between them and victory stands self-interest.

The galaxy’s great powers would rather pursue their own agendas than stand together against this shared terror. Human and inhuman interests wrestle to control Idris’ discovery, as the galaxy erupts into a mutually destructive and self-defeating war. The other great obstacle to striking against their alien threat is Idris himself. He knows that the Architects, despite their power, are merely tools of a higher intelligence.

Deep within unspace, where time moves differently, and reality isn’t quite what it seems, their masters are the true threat. Masters who are just becoming aware of humanity’s daring—and taking steps to exterminate this annoyance forever.
