The road between the stars was not built for us. But we found it.

At a multinational deep-space observatory orbiting Jupiter, theoretical physicist Dr. Alina Rao detects an anomaly in the spacetime curvature at the planet’s L2 Lagrange point.

It is precise. It is periodic. And it is not natural.

What begins as a measurement becomes a revelation: a quantum phase corridor, engineered, ancient, and stretching thousands of light-years into the galaxy.
When a probe is sent to investigate and returns molecularly transformed, carrying atoms forged in another star, Rao and her team must confront a discovery that
rewrites humanity’s place in the cosmos.

But the corridor responds to observation. Every measurement feeds its energy.
And as governments fight for control and military factions push for immediate human transit, the team faces an impossible choice: risk destroying the greatest discovery in history, or accept that humanity is not yet ready to use it.

First contact did not come through communication. It came through inherited risk.

The Quantum Drift is the second book in The Threshold Protocol series, a standalone hard science fiction for readers who want their physics real, their stakes existential, and their sense of wonder earned.

Perfect for fans of Greg Egan, Peter Watts, Andy Weir, and Arthur C. Clarke.
