Steve Coll investigates the largest and most powerful private corporation in the United States, revealing the true extent of its power. ExxonMobil's annual revenues are larger than the economic activity in the great majority of countries. In many of the countries where it conducts business, ExxonMobil's sway over politics and security is greater than that of the United States embassy. In Washington, ExxonMobil spends more money lobbying Congress and the White House than almost any other corporation. Yet despite its outsized influence, it is a black box.

Private Empire pulls back the curtain, tracking the corporation's recent history and its central role on the world stage, beginning with the Exxon Valdez accident in 1989 and leading to the Deepwater Horizon oil spill in the Gulf of Mexico in 2010. The action spans the globe, moving from Moscow, to impoverished African capitals, Indonesia, and elsewhere in heart-stopping scenes that feature kidnapping cases, civil wars, and high-stakes struggles at the Kremlin.

At home, Coll goes inside ExxonMobil's K Street office and corporation headquarters in Irving, Texas, where top executives in the 'God Pod' (as employees call it) oversee an extraordinary corporate culture of discipline and secrecy.
