The Consent Protocol: The Nexuum, #4 – Kobo eBook

Beneath the volcanic rock of Cappadocia, a drill breaks through eleven metres of solid stone into a room that should not exist.

The chamber has hand-cut walls. Modern electrical wiring. A swept floor.

And a woman answers from the other side.

At Karanlkdere, a protected underground complex already threatened by progressive structural failure, the discovery should be impossible. Every survey says there is solid rock beyond the bore. Every control point agrees. Yet the voice is real enough to answer questions, describe the corridor around herand insist that on her map, the room has always been there.

The Vatican’s secretive Officium Nexuum sends surveyor Andrea Vandi to investigate.

Andrea has learned not to trust extraordinary explanations until every ordinary one has failed. He checks the instruments. The control network. The drill orientation. The historic plans. But each independent test makes the impossible harder to dismiss.

The space beyond the rock is not an empty pocket or a forgotten excavation. It belongs to a coherent environment that overlaps Karanlkdere without sharing the same physical description.

And people live there.

That turns an engineering emergency into something far more dangerous.

Structural specialist Elias Rainer believes Karanlkdere must be stabilised before a failing roof system becomes catastrophic. His proposed interventions are technically crediblebut changing the load path on one side may damage homes, passages and lives on the other. Closing the public site reduces immediate danger but cannot stop the rock from moving. Evacuation may save people while destroying what they hope to return to. Refusal may protect one community while allowing another structure to fail.

Andrea is forced into a question no instrument can answer:

Who has the right to consent when two realities share the same stone?

There is no single representative. No unanimous answer. No clean division between intervention and inaction. The people beyond the correspondence do not agree with one another, and neither do the experts trying to protect them. Every solution transfers risk. Every delay has consequences. And the structural clock is still running.

As engineers, officials and the inhabitants of the adjacent environment struggle to decide what may be changedand who is permitted to decideAndrea must create rules for a situation no institution was designed to govern.

What counts as proof that an unseen population is real?
Does leaving danger mean consenting to what happens afterward?
Can an emergency justify acting over an explicit refusal?
And if communication disappears, who gets to call silence permission?

The deeper Andrea goes, the less the mystery is about whether two realities can occupy the same ground.

It is about what one reality owes the people living in the other.

Because silence is not consent.

And when two versions of the world share the same stone, saving one may mean permanently altering the other.

THE CONSENT PROTOCOL is Book Four of THE NEXUUM SERIES by Jack Corvenan intelligent speculative mystery-thriller blending impossible geometry, structural engineering, institutional secrecy, ethical conflict and parallel realities into a high-stakes story about evidence, authority and the consequences of deciding for people you cannot fully reach.

The consent dilemma is not cosmetic: the manuscript explicitly rejects treating evacuation as consent and develops the question of what authority may do when an affected population refuses intervention while the structural danger continues.
