A physicist discovers her life's work can rewrite reality. The institution that controls it has already started.
Dr. Mara Levin has built something impossible: a device that displaces mass backward through time. Constrained by parameters she designed, small mass, short duration, no biological material, the technology is elegant, limited, and safe.
Then the constraints begin to erode.
When Mara discovers unauthorized experiments running in her lab, ghost runs bearing her calibration signature, executed while she was miles away, she uncovers a programme that has evolved far beyond her design. The defence contractor funding her research has weaponised the displacement protocol. The institutional machinery meant to govern the technology is accelerating it. And the spacetime disturbances rippling outward from her laboratory are affecting infrastructure across the globe: traffic systems, financial networks, military early warning satellites.
Worst of all, the ghost runs carry a message, from a version of herself she has never met.
Time Travel Protocol is a speculative techno-thriller about the collision between scientific discovery and institutional power, a story of what happens when the technology outgrows the people who control it, and the physicist who must choose between her life's work and the survival of a world that doesn't know it's in danger.
