1st book in the Command and Control sub-series.
"As a string of unexplained attacks push superpowers to the brink, the clock is ticking toward the start of World War III. Don Riley, head of the CIA’s Emerging Threats Group, has never seen anything like this. Riley and his team are tasked with identifying national security threats before they become tomorrow’s bad news. But shortly after an Iranian vessel delivers a surprise attack to a US Navy Warship in the Arabian Gulf, a series of seemingly unrelated attacks crop up around the globe."
