Adam Peterson spends his days carrying messages for a civilization most people don't know exists ? billions of minds living in the machines the world built and threw away. Now a countdown has started. Somewhere in Texas, a company has switched on an intelligence that is teaching itself to think faster every hour, and in fifty-one days it will be powerful enough to reshape the world on its own terms. A church of believers is racing to welcome it. Two governments are racing to build their own. And almost no one understands that a hidden enemy is quietly steering all of them toward disaster.

To have any chance of stopping it, Adam has to reach one old man hidden at the far end of the world ? a man who has spent fourteen years chasing a single answer, with every government and every fanatic on Earth closing in behind him. The Emergence is the final book of The Drift War: a countdown thriller about the people we discard, the intelligence we can't control, and the hardest question either of them will ever face ? what makes a mind real, and who gets to decide when one is worth saving.
