In addition to such ancient disputes, now there was oil, which kept the rest of the world drawn into this combustible place. Although the long-term possibilities offered by cold fusion, the most promising of the new technologies, were startling, its industrial-scale practicality was still unproven—and the world’s store of rich hydrocarbons continued to be burned as fast as they could be dug out of the ground. So, where once the British Empire and Tsarist Russia had faced each other here over the wealth of India, now the United States, China, the African Alliance, and the Eurasian Union, all crucially dependent on the oil reserves of Central Asia, were locked in a tense, mutually dependent standoff.

The UN’s mission here was to keep the peace by surveillance and policing. The area was said to be the most heavily scrutinized of any territory on Earth. The peacekeeping mission was an imperfect, heavy-handed regime that, Bisesa sometimes thought, created as much tension and resentment as it resolved. But it worked after a fashion, and had done so for decades. Perhaps it was the best mere human beings, and the complicated, flawed but enduring political lash-up of the UN, could do.

Everybody at Clavius knew the importance of the job. But there were few things more boring for a young soldier than peacekeeping.

Suddenly the ride got a lot more bumpy. Bisesa felt her pulse rate rise; maybe this mission wasn’t quite so routine after all.

As the chopper continued to circle, despite the turbulence, Casey and Abdikadir were both working, both talking at once. Abdikadir was trying to raise the base. “Alpha Four Three, this is Primo Five One, over. Alpha Four Three …” Casey was swearing, something to do with losing the positioning satellite contact, and Bisesa surmised he was flying the chopper by hand through the unexpected turbulence.
