In his chilling new book, New York Times bestselling author Kenneth R. Timmerman blows the lid off the greatest threat America faces: the Islamic Republic of Iran.

Using his exclusive access to previously classified documents, Iranian defectors and officials, and high-level sources in the U.S. government and intelligence community, Timmerman blows the lid off previously unreported threats and our intelligence community’s failure to deal with these dangers.

And now it could be too late.

To get the complete story on Iran’s radical Islamic regime, Timmerman crisscrosses the globe, taking the reader into secret terrorist gatherings in Tehran, into tense meetings in the White House, to debriefings at an obscure CIA outpost in Azerbaijan, to diplomatic face-offs in the Kremlin, and to many other spots along the way. His extensive investigative reporting allows him to lay bare the true nature of the Iranian threat.

For Americans interested in the truth about Iran, Countdown to Crisis may amount to a call for action–or even a case for war.
