I tried not to pin my own hopes and fears on him. But I couldn’t help thinking that for all our differences we were more alike than not. I found myself wondering whether he might have crossed paths with Allison Pearl back in the impossibly distant twenty-first century, some chance encounter in a faceless American crowd. Surely if anyone in Vox Core was equipped to understand Allison Pearl, it was Turk. So maybe it wasn’t surprising that on one of those nights when neither of us could sleep I went into his room for comfort. We talked at first, the kind of talk we could have with no one but ourselves, intimacies shared not because of but despite what we knew about each other. “I am the thing most like you in the world,” I said, “and you’re the thing most like me,” at which point it was inevitable that we would go to bed and take some solace there, and in the end I didn’t care what the walls might hear or to whom they might whisper their dangerous secrets.

In the morning I toured him through Vox Core, heel to head.

Of course he couldn’t see all of it, or even more than a representative fraction. Vox Core above ground was the size of a modest twenty-first-century city. Below ground, in the hollow of the island, it was bigger: unravel all those complex spaces onto a two-dimensional grid and it would have been the size of Connecticut or maybe even California. We avoided the damaged zones that were still being decontaminated and rode vertical transit downward. We paused whenever the tube walls allowed a broad perspective, so Turk could see the plazas and terraces and tiers, the wide agricultural levels bathed in artificial daylight, the dormitory complexes set like alabaster chips in forested wildspaces.

Then I took him to the lowest levels of Vox, the engineering decks. The engines that drove Vox were immense—more a territory than an object—but I showed him reactor units the size of small towns, bathed in an eternal wash of desalinated water; I showed him a shadowy acreage of mu-metal chambers in which magnetic fields directed flows of molten iron; I led him past superconductive field coils around which moisture condensed like snow and was swept away in gales of forced air. Turk was awed, which would play well with the administrators who were no doubt monitoring us. There were ears in the walls even here.

But there were no ears where I took him next. We rode a transit stem up as far as it would go, then transferred to a smaller transport that slid up the spine of Vox’s tallest tower. Two more transfers and we arrived at the highest accessible public platform in Vox Core, essentially a roof with a view.
