He’d spoken with men and women from everywhere in the system. From the way someone said allopolyploidy, he could tell if they came from the universities around Beijing or Brazil, if they’d grown up in the shadow of the Rocky Mountains or Olympus Mons or in the corridors of Ceres. He’d grown up in microgravity himself, but Belt patois was as foreign to him as to anyone fresh up the well. If the boy had wanted to speak past him, it would have been effortless.

A month before, the boy might have been skimming commercial data to resell or hold hostage for easily laundered private credit. Today he was looking for Mei in exchange for enough leafy greens to make a small meal. Agricultural barter, the oldest economy in humanity’s record, had come to Ganymede.

“Authcopy’s gone,” the boy said. “Sucked into servers, buried ass deep.”
