David Swift, a professor at Columbia University, is called to the hospital to comfort his mentor, a physicist who's been brutally attacked. Before dying, the old man wheezes 'Einheitliche Feldtheorie.' The Theory of Everything. The Destroyer of Worlds. Could this be Einstein's proposed Unified Theory- a set of equations that combines the physics of galaxies with the laws of atoms? Einstein died without discovering the theory. Or did he?

Within hours of hearing these words, David is arrested, interrogated, and nearly assassinated. The FBI and a ruthless mercenary are vying to get their hands on the long-hidden theory. But why? Teaming up with his old girlfriend (who happens to be a brilliant Princeton scientist), David goes on the run, frantically working out Einstein's final theory and revealing the staggering scope of its consequences.
