As Washington struggles to keep the crisis from becoming a war, civilian defense contractor Patrick Kendrick is pulled into a pattern hidden inside old land records, broken archives, and a name nobody wants to recognize: Project Hidden Wife.

What begins as a search for the source of one impossible blast becomes a race through buried Cold War architecture, abandoned command logic, and officials fighting over how much truth a frightened country can survive. The danger is not only what was left underground. It is the silence that kept it alive.

On the Clift Edge is a geopolitical techno-thriller about secrecy, accountability, and the terrible cost of systems built to outlive human judgment.
