FOUNDATION

by Andi Anriansyah ...

Series Book 1 - The Hidden Layer
Geotechnical engineer Reza Sarwono expects an ordinary anomaly when a routine core sample beneath the Apex Spire construction site in Meridian City comes back wrong. What she finds instead — a resonance no rock should produce, a dating result that shouldn't be possible, a geometry too precise to be natural — will end her career as she knows it and begin something far larger.As government ...

by Jerry Gani, Andi Anriansyah ...

Series Book 1 - Dark Shift
The deeper they drill, the less the planet behaves like geology.Chief drilling engineer Rangga Ilori arrives at Meridian-9 carrying the scars of a career-defining disaster. His mission seems simple: rescue an offshore deep-drilling project that has already consumed two failed wells, millions in investment, and the confidence of everyone involved.But the numbers refuse to make sense.An unexplained ...

Series Book 2 - The Hidden Layer
A year after Meridian City's discovery was quietly sealed, a heritage building in Tokyo survives an earthquake it should never have survived. Structural engineer Kenji Ashida can't explain why — until statistician Grace Okonkwo's models connect his data to a growing, uncomfortable pattern: identical structural signatures appearing in cities that have never shared so much as a sensor feed.When an ...

Series Book 5 - Heat Below
The Earth Systems Observatory was built to answer the question the Task Force couldn't: not whether the world's geothermal reservoirs are connected, but how to manage a system too large for any single model to hold.When the Observatory's first blind prediction is put to the test — with real consequences riding on a number nobody can fully verify in advance — the team built around Rani Kusuma, ...

LAST DESCENT

by Andi Anriansyah ...

Series Book 7 - The Deep Vein
The graph had been climbing for eleven days before anyone thought to show it to Sarah Kessler. Fourteen weeks, and counting, before the network's deepest chamber reaches a failure threshold with no name yet — only a number, and seven books' worth of accumulated knowledge about to be asked, all at once, what it actually adds up to.LAST DESCENT reunites the full ensemble of THE DEEP VEIN for one ...

Series Book 5 - The Hidden Layer
Three years after the four-city crisis, the task force has settled into something like routine — until a resonance anomaly beneath the stabilized Hub reveals a depth that shouldn't exist. Hydrogeologist Farah Haddad asks the one question no one thought to ask about a two-thousand-year-old stone network: where does the water go?The answer leads Reza Sarwono's team into a water-distribution gallery, ...

Series Book 6 - The Hidden Layer
Five months after the Deep Foundation is confirmed and formally placed under international stewardship, a routine survey turns up a signature at a depth the network's own boundary should have made impossible. What Reza Sarwono's team finds beneath that boundary isn't another regulating node — it's a buried civic district, intact, silent, and built by a civilization that left behind not ruins, but ...
