Final Theory : David Swift, a professor at Columbia University, is called to the hospital to comfort his mentor, a physicist who's been brutally tortured. 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 never succeeded in discovering it. Or did he? Within hours of hearing his mentor's last words, David is running for his life. The FBI and a ruthless mercenary are vying to get their hands on the long-hidden theory. Teaming up with his old girlfriend, a brilliant Princeton scientist, David frantically works out Einstein's final theory to reveal the staggering scope of its consequences.
