I recently read “The Increment” by David Ignatius. It is a fictional setting about Iran and its attempts to build nuclear weapons. Here is a snippet about the book from Publisher’s Weekly: “When Harry Pappas, the new CIA chief of the Iran Operations Division, receives an unsolicited e-mail from an alleged Tehran scientist who calls himself Dr. Ali that implies Iran has in fact continued with its nuclear weapons program and is an imminent threat to global peace, he shares the information with his superiors only to find an administration bent on warmongering. Having vowed never again to play a role in a senseless conflict that could potentially kill thousands of innocents, Pappas, whose only son was killed while serving in the second Iraq War, must somehow identify Dr. Ali, get him out of Iran and mine his knowledge before the U.S. blunders into another unnecessary war.”

The book took some time taking off, but once it does, it is very good and fast. Plenty of twists and turns to keep one engrossed through to the end. What also helps is that the topic is also quite contemporary.
