3rd book in the Command and Control sub-series.
"A conflict in Ukraine threatens to escalate into a global power struggle between the United States and Russia. When mercenaries attack in eastern Ukraine, the world is thrust into turmoil. Russian President Luchnik is quick to respond, launching a full-scale military invasion to quell this "national emergency" in the former Soviet country. Don Riley, head of the CIA's Emerging Threats Group, sees trouble ahead. The Russian President is hungry for power, and he's got the military might to back up his grand ambitions. The Russian attack in Ukraine is the first move in a much larger campaign that will redraw the map of Europe."
