New York Times bestselling author Joel C. Rosenberg returns with a high-stakes political thriller set in Russia. Everything he learned to protect the president, he must use to take out theirs. With an American president distracted by growing tensions in North Korea and Iran, an ominous new threat is emerging in Moscow. A czar is rising in the Kremlin, a Russian president feverishly consolidating power, silencing his opposition, and plotting a brazen and lightning-fast military strike that could rupture the NATO alliance and bring Washington and Moscow to the brink of nuclear war. But in his blind spot is the former U.S. Secret Service agent, Marcus Ryker, trained to protect but ready to kill to save his country

As the apocalyptic leaders of Iran call for the annihilation of Israel and the U.S., CIA operative David Shirazi is sent into Tehran with one objective: use all means necessary to disrupt Iran's nuclear weapons program, with leaving American fingerprints, and without triggering a regional war. At extreme personal risk, Shirazi executes his plan. A native Faris speaker whose family escaped from Iran in 1979, he couldn't be better prepared for the mission. But none of his training has prepared Shirazi for what will happen next. An obscure religious cleric is suddenly hailed throughout the region as the Islamic messiah known as the Mahdi or the Twelfth Imam. News of his miracles, healings, signs and wonders spread like wildfire, as do rumors of a new and horrific war. With the prophecy of the Twelfth Imam seemingly fulfilled, Iran's military prepares to strike Israel and bring about the End of Days. Shirazi must take action to save his country and the world, but the clock is ticking and then a dark secret from his past comes to light and changes the course of his life forever
