From its genesis in North Korea, Z7R2 is racing around the world unchallenged, a fatal virus infecting tens of millions. The world is now severed into two partitions: those who must wear a red mask to show their infected status, and those with white masks, who give the reds a wide berth. The world's pharmaceutical companies scramble with little success to unearth a treatment or vaccine. After an appeal from their friend, FBI agent Matthew Johnson, Jon Levine and Alyssa Martin join the hunt for a way to combat this deadly disease. Together they learn the shrouded secrets behind this toxic invasion, and find themselves careening from Los Alamos, to a meeting with Mossad operatives in their home, a midnight execution in Geneva, meetings in Tel Aviv and Tehran, and ultimately, the White House itself.
