Even his concept of geography has changed. When he was home, he sat down with his grandparents and they looked at the globe, spinning it around until all they saw was blue, tracing his route across the Pacific, from one lonely volcano to the next godforsaken atoll. Waterhouse knows that those little islands, before the war, had only one economic function: information processing. The dots and dashes traveling along the undersea cable are swallowed up by the earth currents after a few thousand miles, like ripples in heavy surf. The European powers colonized those islands at about the same time as the long cables were being laid, and constructed power stations where the dots and dashes coming down the line were picked up, amplified, and sent on to the next chain of islands.
