In 500 Days, New York Times bestselling author Kurt Eichenwald lays bare the harrowing decisions, deceptions, and delusions of the eighteen months that changed the world forever, as leaders raced to protect their citizens in the wake of 9/11.

Eichenwald puts readers at the heart of these historic events, from the Oval Office to Number 10 Downing Street, from Guantanamo Bay to CIA headquarters, from the al Qaeda training camps to the torture chambers of Egypt and Syria. He reveals previously undisclosed information, including details about warrantless wiretapping, the anthrax attacks, and investigations and conflicts among Washington, D.C., and London.

500 Days exposes a world of secrets and lies that has remained hidden until now.
