A murdered professor. Two words written in blood. An equation that could change everything.

Nathan Brooks was a mathematician going through the motions — publishing papers, chasing tenure, measuring his life in productivity metrics — until his mentor was killed for a discovery he'd spent forty years documenting.

Now Nathan has the key to the research, a former intelligence operative at his side, and a target on his back.

The equation is elegant. What it proves is explosive, and the organization that has spent more than two centuries burying it will do whatever it takes to make sure Nathan never shares it with the world.

What would you risk to know the truth?
