-Amazon Reviewers

Scott Anderson never asked to be a revolutionary. He only wanted a quiet life surrounded by equations, far from the political violence tearing his world apart. But when fascist forces begin targeting his family, Scott is forced to flee everything he knows — trading safety for survival and stumbling headlong into a scientific research project where the most brilliant physicist alive is pushing humanity toward a discovery that could change everything.


The problem? Someone — or something — has already decided that humanity isn't ready.


The alien sentinels have watched Earth for over a hundred years. Their directive is simple and merciless: no species advances primordial black hole technology. The rules aren't negotiable. Prevention is insidious. Violations bring swift enforcement. Orbital bombardments rain down on research facilities, silencing physicists who come too close to the truth. Scott finds himself caught between earthly fascists and cosmic enforcers, forced to ask a terrifying question — in a universe governed by power, is the pursuit of knowledge itself an act of war?
