“Well, they still want to send up emigrants, that’s part of the overall strategy. And resistance to the one-child rule has been stronger in some Catholic and Muslim countries, and several of those nations would like to colonize Mars as if it were empty. The threat shifts now, from India and China to the Philippines, Brazil, Pakistan.”

“Hmm,” Zo said. Talk of immigration always made her feel oppressed. Threatened by lemmings. “What about the exmetas?”

“The old Group of Eleven is rebanding in support of the strongest of the old metanats. They will be looking for places to develop. They’re much weaker than before the flood, but they still have a lot of influence in America, Russia, Europe, South America. Tell Jackie to watch what Japan does in the next few months, she’ll see what I mean.” They connected up wristpads so that the woman could make a secure transfer of detailed information for Jackie.

“Okay,” Zo said. Suddenly she was tired, as if a heavy man had crawled into the exoskeleton with her and were dragging her down. Earth, what a drag. Some people said they liked the weight, as if they needed that pressure to be convinced of their own reality. Zo wasn’t like that. Earth was the very definition of exoticism, which was fine, but suddenly she longed to be home. She unplugged her wristpad from the translator’s, imagining all the while that perfect middle way, that perfect test of will and flesh: the exquisite gravity of Mars.

Then it was down the space elevator from Clarke, a trip that took longer than the flight from Earth; and she was back in the world, the only real world, Mars the magnificent. “There’s no place like home,” Zo said to the train-station crowd in Sheffield, and then she sat happily in the trains as they flowed over the pistes down Tharsis, then north to Echus Overlook.

The little town had grown since its early days as the terraforming headquarters, but not much; it was out of the way, and built into the steep east wall of Echus Chasma, so that there wasn’t much of it to be seen— a bit on the plateau at the top of the cliff, a bit at the bottom, but with three vertical kilometers between the two, so that they were not visible one from the other— more like two separate villages, connected by a vertical subway. Indeed if it weren’t for the fliers, Echus Overlook might have subsided into sleepy historic-monument status, like Underhill or Senzeni Na, or the icy hideouts in the south. But the eastern wall of Echus Chasma stood right in the path of the prevailing westerlies that came pouring down the Tharsis Bulge, causing them to shoot up in the most astonishingly powerful updrafts. Which made it a birding paradise.
