Book One of The Measured World is published today, 14 August 2026, in ebook and paperback.
Nine billion people walked into the water. One equation decided who survived. Defne Ata wakes in a city that has been waiting for her, and on the terminal in her room there is a single line that tells her exactly what kind of machine she is living inside: Recommended sequence available.
The system has a preferred order for grief.
Pre-order open. The same weeks as The Survival Index, from the other side of the wall. Either book can be read first.

Releasing 14 August 2026. Pre-order open now.
See the book →→The companion archive for The Survival Index is now open: twenty-two hubs, four tiers, and spoiler-light world files. An interactive hub network map is available on the World page.
Explore the World→Six declassified foundational briefs are now open. Real research reframed as SIREN institutional documents — neural entrainment, antimicrobial resistance, nanoparticle medicine, ecological overshoot, AI modelling, and the Signal.
