“Left over from New Year’s,” he said. “Never mind that now. We also wanted to thank you for stepping in with Tayla’s little problem out there. She told us about it when she came home.”

“It’s not the usual way to meet your new housemate,” Tayla said.

“Let’s not make it a regular thing,” I said.

“I would be okay with that,” Tayla said.

“And these are your other new flatmates,” Tony said, pointing at the two remaining threeps. “That’s Sam over there—”

“Hey,” Sam said, raising a hand.

“Hello,” I said.

“—and this is the twins, Justin and Justine,” Tony said, pointing to the remaining threep. I was about to ask for clarification when a text popped into my field of vision, from Tony. Go with it, I’ll explain later, it said.

“Hello,” I said, to the twins’ threep.

“Hello,” at least one of the twins said back.

“Can we do anything for you to make you comfortable?” Tony asked. “I know you’ve had a fun-filled couple of days.”

“Actually, all I want to do right now is get some sleep,” I said. “I know that’s not very exciting, but it’s been a really long day.”

“Not a problem,” Tony said. “Your room is like you saw it the last time you were here. The desk chair has an induction pad in it. It should work for you until you get something better in there.”

“Perfect,” I said. “In that case, good night, everyone.”

“Wait,” said the twins, and then handed me a balloon. “We forgot to throw this at you when you came in.”

“Thanks,” I said, taking it.

“We blew it up ourselves,” the twins said.

I thought about the implications of that statement. “How?” I finally asked.

“Don’t ask,” they said.

Chapter Twelve

AND OF COURSE I couldn’t sleep. After three hours of trying I finally gave up and went to my cave.

For a Haden, personal space is a touchy subject. In the physical world there has always been a debate on how much space a Haden actually needs. Our bodies don’t move and most of them are in specialized medical cradles of greater or lesser complexity. A Haden needs space for their cradle and the medical equipment that attaches to it, and strictly speaking that’s all we need.

Likewise, for our threeps, space shouldn’t be an issue. Threeps are machines, and machines shouldn’t need personal space. A car doesn’t care how many other cars are in the garage. It just needs space to get in and get out. Put both of those together, and when people first started designing spaces for Hadens and their threeps, they were all like the efficiency apartments LaTasha Robinson showed me: small, clinical, no-nonsense.

Then people started noticing that Hadens had developed a spike of major depression, independent of the usual causes. The reason was obvious if anyone took any time to think about it. Haden bodies might be limited to their cradles, and threeps might be machines, but when a Haden was driving a threep, they were still a human being—and most human beings aren’t happy feeling like they live in a closet. Maybe Hadens don’t need as much physical space as naturally mobile people, but they still need some. Which is why those efficiency apartments were the Haden residence of last resort.

In the nonphysical world (not the virtual world, because for a Haden the nonphysical world is as real as the physical one) there is the Agora, the great global meeting place of the Hadens. Dodgers—the people who aren’t Hadens—tend to think of it as something like a three-dimensional social network, a massively multiplayer online game in which there are no quests, other than simply standing around, talking to each other. One reason they think this is because the public areas open to Dodgers (and yes, we call them Dodger Stadiums) work very much like that.

Explaining how the Agora works to someone who is not a Haden is like explaining the color green to someone who is colorblind. They get a sense of it, but have no way to appreciate the richness and complexity of it because their brains literally don’t work that way. There’s no way to describe our great meeting places, our debates and games, or how we are intimate with each other, sexually or otherwise, that doesn’t sound strange or even off-putting. It’s the ultimate in “you have to be there.”

For all of that, in the Agora proper, there is no substantial sense of privacy. You can close off the Agora for periods of time, or temporarily create structures and rooms for exclusivity—people are still people, with their cliques and groups. But the Agora by design was built to create a community for people who were always and inevitably isolated in their heads. It was built open on purpose, and in the two decades since its creation it had evolved into something with no direct analogue to the physical world. It’s an openness that leaks into how Hadens deal with each other in the physical world as well. They leave their IDs visible, have common channels, and swap information in a way that would strike Dodgers as promiscuous and possibly insane.

Not all Hadens, mind you. Hadens who were older when they contracted the disease were tied more deeply into the physical world, where they had already spent almost all of their lives. So after contracting the disease, they lived mostly in their threeps and used the Agora—to the extent they used it at all—as a glorified e-mail system.

The flip side of this were the Hadens who contracted the disease young and were less attached to the physical world, preferring the Agora and its system of living to forcing their consciousness into a threep and clanking through the physical world. Most Hadens existed between the two spaces, both in the Agora and in the physical world, depending on circumstance.

But at the end of the day, neither the physical world nor the Agora could provide what most Hadens really needed: a place where they could be alone. Not isolated—not the lock in that Haden’s syndrome forced on them—but by themselves, in a place of their own choosing, to relax and to think calmly. A liminal space between worlds, for themselves and the select few that they chose to let in.

What that liminal space is depends on who you are, and also the computing infrastructure you have to support it. It can be as simple as a house from a template, stored on a shared server—free “tract housing” supported by ads that presented themselves in picture frames, which computationally collapsed once the Haden went out the door—to immense, persistent worlds that grew and evolved while the very rich Hadens who were the worlds’ owners resided in floating palaces that hovered over their creations.

My liminal space was something in between those two. It was a cave, large and dark, with a ceiling from which glow worms hung, imitating a nighttime sky. It was, in fact, a re-creation of the Waitomo Caves in New Zealand, if the caves were about ten times larger and had no traces of being a tourist attraction.

In this cave, cantilevered out over a dark, rushing subterranean river, was a platform on which I would stand, or sit in the single, simple chair I put there.

I almost never let people into my cave. One of the few times I did was when I was dating another Haden in college, who looked around, exclaimed, “It’s the Batcave!” and started to laugh. The relationship, already a bit rocky, blew up not long after that.

These days I think the comment was more on point than I would like to admit. Up to that point I had spent a lot of my time being a public person whose movements were followed no matter where I was. My own space was dark and silent, a place where I could be an alter ego—one who could methodically hack away at homework, or muse on whatever notions of mine were posing as deep thoughts at the time.

Or in this particular case, attempt to fight crime.

Over the last two days, too much had been happening to allow me to spin out all the connections among events, to process the data and maybe get something useful out of it. Now was the time. I was up and awake anyway.
