A stolen US army drone. A shrinking oasis in the Sahara Desert. A secret stash of deadly chemicals. Each is a threat to the stability of the world but individually are problems that can be overcome. In the diplomatic arena though, everyone will have a different way of dealing with such a threat. And when those in charge disagree and refuse to back down, it will kick off an international chain reaction with potentially catastrophic consequences: a world edging closer to war... Now three people must work tirelessly and with the utmost skill to stop that from happening: A spy working undercover with jihadists. A brilliant Chinese spymaster. A US president beleaguered by a populist rival for the next election. The only question is, in a game of brinksmanship can the inevitable ever be stopped?
