Damascus Countdown - Joel C. Rosenberg

All eyes are on the Middle East. Israel has successfully launched a first strike on Iran, taking out all of their nuclear sites and six of their nuclear warheads--and causing The Twelfth Imam to order a full-scale retaliation. US President William Jackson threatens to support a UN Security Council resolution condemning the Jewish State for unprovoked and unwarranted acts of aggression.
Meanwhile, CIA operative David Shirazi has infiltrated the Iranian regime and intercepted information indicating that two Iranian nuclear warheads survived the attack and have been moved to a secure and undisclosed location. In danger not only from the ongoing missile strikes on Iran but also from the increasingly hostile and suspicious governments of multiple countries, David and his team are in a race against time to find the remaining nuclear warheads before disaster strikes.
