For more than fifty years, the world's brightest nuclear scientists have died in accidents, mysterious disappearances, unexplained suicides, and unsolved murders. Every investigation ended the same way—closed, forgotten, buried beneath layers of classified documents.
When investigative journalist Daniel Brooks receives an anonymous package containing the names of seventy-three dead scientists, he notices one impossible detail: every victim once worked on a secret project that officially never existed.
As Daniel digs deeper, he uncovers fragments of Silent Nuclear Code, an abandoned Cold War program designed to create an autonomous nuclear command system capable of launching weapons without human approval. The project was supposedly destroyed decades ago.
But someone has been eliminating everyone connected to it.
Hunted by intelligence agencies, private military contractors, and invisible enemies who always seem one step ahead, Daniel discovers that the system has never been deactivated—it has only been waiting.
Now the countdown has already begun.
If the final encryption key is activated, humanity may lose control of its most devastating weapons forever.
Some secrets protect nations.
Others threaten civilization itself.
