The Nemesis manifesto / Eric Van Lustbader.

"Evan Ryder is a lone wolf, a field agent for a black-ops arm of the DOD, who has survived unspeakable tragedy and dedicated her life to protecting her country. When her fellow agents begin to be systematically eliminated, Evan must unravel the thread that ties them all together ... and before her name comes up on the kill list. The list belongs to a mysterious cabal known only as Nemesis, a hostile entity hell-bent on tearing the United States apart. As Evan tracks them from Washington D.C. to the Caucasus Mountains, from Austria to a fortress in Germany where her own demons reside, she unearths a network of conspirators far more complex than anyone could have imagined. Can Evan uproot them before Nemesis forces bring democracy to its knees?"--Publisher's description.
