The Final Architecture Tome 3 (Broché)

He can end their war but will humanity survive to see it ? 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 the galaxy's great powers would rather pursue their own agendas than stand together against this shared terror. As the galaxy erupts into a mutually destructive and self-defeating war, human and inhuman factions wrestle to control Idris's discovery.
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. And deep within unspace, where time and reality move differently, the Architects' masters are becoming aware of humanity's daring - and taking steps A exterminate this annoyance for ever.
