on the outside.”
I held that thought for a moment, trying to keep it at a reassuring distance.
“There are stairs carved into the cliff,” she added. “You can’t see them from this angle. But they were cut during the original construction, so they’re probably somewhat eroded.” Even the foamed-granite composite the islands were made of couldn’t resist wind and salt water indefinitely. “It won’t be an easy climb.”
“The top of the tunnel is a curved surface, and it looks pretty slick.”
“It may be wider than you think.”
“Or it may
“We don’t have a choice.”
But it was too late to begin the attempt, with only a couple of hours of daylight left.
We set up a fresh camp back in the forest. I watched Treya take another hit from her drug syringe. I said, “Is that thing bottomless?”
“It refills itself. It has its own metabolism. It draws a little blood during the injections and uses that as raw material to catalyze active molecules. It runs on body heat and ambient light. For you, it fabricated a drug to suppress anxiety. What it gives me is something different.”
I had stopped taking doses when she offered them—I had decided to live with my anxiety, for better or worse. “How does it know what to synthesize?”
She frowned the way she did whenever she tripped over a concept for which her ghostly tutor Allison Pearl didn’t have a ready word. “It samples blood chemistry and makes an educated guess. But no, it isn’t bottomless. It needs to be refreshed, and this one is getting tired.” She added, “If you want to use it, though, that’s all right.”
“No. What’s it giving you?”
“A kind of… you could call it a cognitive enhancer. It helps maintain the boundary between my real and my virtual memories. But it’s only a temporary solution.” She shivered in the firelight. “What I really need is the Network.”
“Tell me about the Network. It’s what, some kind of internal wireless interface?”
“Not exactly what you mean by that, but yes, in a sense. Except that the signals I receive are expressed as biological and neurological regulators. Everybody on Vox wears a node, and we’re all linked by the Network. The Network helps us formulate a limbic consensus. I don’t know why it hasn’t been repaired. Even if the transponders at Vox Core were destroyed, workers should have been able to restore basic functionality by now. Unless the processors themselves were damaged… but they were built to sustain anything short of a direct hit from a high- yield weapon.”
“Maybe that’s what happened—a direct hit.”
She shrugged unhappily by way of response.
“Which means there’s a good chance we’re marching toward a radioactive ruin.”
“We don’t have a choice,” she said.
I sat up after she fell asleep, nursing the fire.
Without the calming drugs, my own recent memories had begun to firm up. Just days ago I had been trying to survive a series of earthquakes generated by the temporal Arch as it rose from its dormant state in the Equatorian desert. Now I was here on Vox. You can’t really comprehend events like that, I thought. You can only endure them.
I let the fire burn down to a glow of embers. The Arch of the Hypotheticals glimmered overhead, an ironic smile among the stars, and the rush of the sea was amplified by the echo from the nearby cliffs. I wondered about the people who had nuked Vox Core, the “cortical democracies,” and why had they done it, and whether their reasons were as superficial as Treya had suggested.
I was a neutral in the conflict, insofar as that was possible. It wasn’t my fight. And I wondered whether Allison Pearl, the Champlain Ghost, might be similarly neutral. Maybe that was what Treya found so disconcerting: “Allison” and I were both shades of a disinterested past, both potentially disloyal to Vox Core.
6.
We broke camp at dawn and followed the curving cliff until we came to what Treya had called “stairs,” broad declivities cut into the face of the granite. Time had beveled the steps into sloping ledges separated by giddy ten- foot drops. Every surface was slick with mossy growths and bird dung, and the deeper we descended the louder the roar of the ocean became. Eventually the high edges of the two adjoining islands closed off all of the sky apart from a few slanting rays of sunlight. We made slow progress, and twice we paused while Treya took hits from her high- tech syringe. Her expression was grim and, under that, terrified. She kept glancing backward and up, as if she was afraid we were being followed.
By the angle of the light I guessed it was past noon when I helped her down the last vertical gap to the roof of the tunnel itself. The roof of the tunnel was broader than it had looked from above and we were able to stand on it safely enough, though it was unnerving to walk on a surface that rounded away on both sides to a sheer drop. It was maybe a half mile to the opposite anchor point, now concealed by mist, where we would have to do another round of serious climbing, with any luck before darkness set in. Night would come fast down here.
For the sake of distraction I asked Treya what she (or Allison Pearl) remembered about Champlain.
“I’m not sure it’s safe to answer that question.” But she sighed and went on: “Champlain. Cold winters. Hot summers. Swimming in the lake at Catfish Point. My family was broke most of the time. Those were the years after the Spin, when everybody was talking about how the Hypotheticals might actually be benevolent, protecting us. But I never believed that. Walking down those Champlain sidewalks, you know the way concrete glitters in the summer sun? I couldn’t have been more than ten years old but I remember thinking that was how we must look to the Hypotheticals—not just us but our whole planet, just a glimmer underfoot, something you notice and then forget.”
“That’s not how Treya talks about the Hypotheticals.”
She gave me an angry look. “I
Maybe so. Before long we reached the midpoint of the transit, where the wind came roaring between the chasm walls in a focused gale and we had to crawl on our hands and knees like ants clinging to a rainy clothesline. Conversation was impossible. Intermittent vibrations came through the palms of my hands from the tunnel, as of metal groaning under incalculable stress. I wondered what it would take to tear this damaged archipelago apart— another nuclear attack? Or something as simple as a high sea and a strong wind, given what had already happened? I pictured cables the size of subway trains snapping, island-ships like battered pinatas spilling their contents into the sea. It wasn’t a reassuring thought. If not for Treya I might have turned back. But if not for Treya I wouldn’t have been here in the first place.
Finally we came into the shadow of the opposing cliff wall, where the wind eased to a low moan and we could stand upright again. The stairs that had been cut into the granite cliff were identical to those across the gorge: eroded and mossy, steep and stinking of the sea. We had climbed about a dozen of them when Treya gasped and came to a dead halt.
The ledge above us was full of people.
