Drift Protocol: Silent Foundation. The Drift Protocol Trilogy, #3

The Drift event was supposed to be over. Months after a resonance cascade nearly synchronized every human mind on Earth, the world has accepted Horizon Research's explanation and moved on. Elias Vance hasn't. Beneath the Arctic ice, the ancient chamber that triggered the event is still active, its signal buried inside the planet's cognitive field. Then Horizon detects the same harmonic structure arriving from deep space.
As the signal aligns with the chamber, the global lattice begins rebuilding itself. Strangers share thoughts. Scientists make identical discoveries without contact. People across continents dream of structures they have never seen. The civilization that built the chamber reached perfect unity-and never separated again. With the alignment window closing, Horizon must decide whether to break the connection or answer it.
First contact may offer humanity a place inside something larger. It may also erase the distance that makes every mind its own. Humanity was never discovering the network. It was being invited back into it.
