Present Day Wall Street. Where intelligence agencies and the financial industry are strange bedfellows, and the two worlds are often intertwined in disturbing ways. In this chillingly plausible, controversial scenario of a military/industrial/financial complex run amok, Zero Sum pits Dr. Steven Archer Cross against powerful financier Nicholas Griffen in a conflict that raises troubling questions about our markets and our government. Racing against the clock in a chase that spans continents, one man's battle to expose the Machiavellian machinations of a ruthless Wall Street marauder forces him into a financial jungle populated by every variety of unscrupulous sociopath - rogue intelligence agencies, Russian mafia oligarchs, drug cartels and terrorist networks. As a white-collar game of chess transitions into a lethal real world cage-fight, Steven finds himself in a deadly showdown, where hunters can quickly become the hunted and blood is the ultimate currency.
