"I spun us up a bit," he said. "I've given us enough momentum for a twentieth of a gee. I didn't want to do more yet, to let the furniture settle. After everything's back in position we can spin back up to a good weight — say, half a gravity. It's the best way to lose weight," he added with a grin. They didn't laugh.

Nobody spoke, in fact, as they went through the house fetching chairs and beds down from the bizarre piles and configurations they had made. Then Aaron spun them up and real weight gradually returned.

As Aaron adjusted the position of the painting over the mantel he heard Livia drop onto the couch behind him. "Now what?" she asked.

"Well," he said, stepping back and eyeing his handiwork, "most of the work was in timing when to throw us off the wall. There's nothing to do now but wait."

Silence. He turned; both Livia and Qiingi sat bolt upright in their chairs. They were waiting. Aaron began to laugh, all of the tension finally ebbing away as he did. "Weeks!" he said. "The next coronal is weeks away. The house is self-healing, the oxygen and heat plants are the best pseudolife we had ... there's really nothing we have to do. This is what space travel is like."

They stared at him, uncomprehending. Finally he just shrugged and went to fetch the house's broombug to clean up a spill in the kitchen.

Later, Aaron and Livia came together in the kitchen. For the first time since her arrival at the aerie, neither was busy with something. They hugged and he gazed intently into her face. "Have I said how proud I am of you?"

She raised an eyebrow. "No, but go ahead. Oh, by the way — about what?"

He laughed. "The others thought we'd lost you after the Oceanus thing. You disappeared at the same time as the rest of the peers. But I kept saying, 'if anybody can make it out it's Livia. She's done it before.'"

Uneasy, Livia broke away. "I'm not special. I was just lucky enough not to be there when they attacked."

"But you led them."

She shrugged irritably. "What does that matter?"

He waved a hand. "It doesn't. It doesn't. As long as you're okay ... And this Qiingi fellow? He helped you?"

She nodded. "Qiingi's a ... very special person. Strong. He doesn't seem to know what the word uncertainty means."

"Huh." He busied himself with the house controls he'd clamped to the kitchen counter.

"Aaron." He looked over, smiling. "Why didn't you tell me you were going away? I mean, I understand if the founders didn't want you to talk about the specifics of the project you were working on. But you could have said it was secret, and left it at that."

He looked blank for a moment. "I didn't want to keep secrets from you. And I didn't want to lie to you."

Livia gave him a puzzled frown. "So vanishing out of my Society was somehow better?"

"Look, I'm sorry. I was ... consumed with the project. It's all I've thought about for weeks. Besides," he said with a grin, "I'm a big boy now. You don't really need me to tell you all my comings and goings, do you?"

That stung, both because Livia knew she shouldn't have to rely on his presence so much anymore — and because once upon a time, she had been able to rely on it without hesitation.

Does that mean we're no longer inseparable? she wanted to ask. But she kept silent They continued chatting, catching up as if nothing had happened. But so much had happened lately; she couldn't sustain the casual tone of the conversation.

Eventually, talk dried up, and they drifted their separate ways.

They gathered over breakfast to discuss their plans. So far the details had been sketchy: all Livia had cared about was escaping Teven. All it took was an eloquent look on her part for Aaron to understand.

"What do we do next? Well, this was the easy part," he began. "The coronals take care of travel between them. Normally we wouldn't have launched from the top of the wall but from one of the cities under the coronal's skin. The skin's only two meters thick at any point and there're lots of doorways and shafts opening into the undersurface."

Livia paused with her fork halfway to her mouth. "I've never heard of anything like that," she said. Qiingi also looked puzzled.

"I've explored some of them," said Aaron. "There's whole cities hanging like chandeliers underneath our feet. But they're in different manifolds. I thought that some of them might know how to use the coronals' transport systems, but it seems that the founders excluded use of the docking systems from the tech locks. They made travel as impossible as long-range radio and laser-com."

"But why?" asked Livia. "Oh," she answered herself. "Because they didn't want us to be found. They wanted to isolate the manifolds here."

"Yes. Which is a shame because from what I've been able to learn, all you'd have to do to travel between the coronals is walk down a flight of stairs and enter a moving stateroom. At the appropriate moment it gets dropped, and you're away. At the far end, grapples pick you up as you fly by the destination coronal on a close tangent. I found pieces of old cargo boxes in some of the underways, and figured out the basics of their labels. We tried various destination labels on the barrels we dropped, and ones with a particular label were picked up and held at the next coronal. So we know the label, or I guess the name, of that coronal: it's called Rosinius in OldWorldLing.

"The system seems fully automatic; there'd be way too much traffic for a human to oversee. But you see, nobody claimed the barrels at the far end. I don't know if anybody noticed them at all. When they weren't claimed after two days, the system returned them. It's that automation that we're going to rely on to get us to Rosinius."

"And if we don't find help there?" asked Qiingi. "Do we travel to the next one? And the next? Then what? Will we be stranded?"

Aaron hesitated. "I don't know. I didn't want to do this in the first place. Of course, we know the Teven label, so we can always come back ... "

"If we're not captured by someone or killed," Livia pointed out. Aaron shrugged.

"Same chance we were taking at home."

Qiingi smiled; it was the first time in days he'd done that Livia smiled back at him. "What next, then? Who is it we seek?"

She hesitated. "The one name I've got to go on is the anecliptics."

"What do we know about them?" Qiingi asked. "Are they founders, like Raven or your Ellis? Or qqatxhana?"

"Well, the name is a clue," said Aaron. "If you squint, you might be able to see what I mean." He waved a piece of bread at the window; weak but direct sunlight slanted in. Livia did squint at the sun, but it looked the way it always did: tiny and fierce, with minute thornlike spikes of intense light hanging just above and below it. The spikes made it look a bit like a sideways eye.

Aaron rose and went to the window. He pointed to one side. "Have you ever wondered where that comes from?"

Livia craned her neck. He was pointing at the faintly drawn, rainbow-colored clouds that hung across one half of the sky. "It's just the Lethe Nebula," she said. "It's always been there."

"Actually, no," said Aaron. "It was never there during ancient times, or the Modern period. I checked old astronomical records. There's nothing about a seventy-million-kilometer-thick cloud orbiting near Jupiter." He pointed again, this time to the brightest star. Livia knew it was Jupiter; that pinprick of light was the only celestial object other than the cloud and the sun that never moved with the seasons. "And did you know," continued Aaron, "that there's another cloud like this one on the opposite side of the sun?"

Livia shrugged. "It's all one thing," he said. "The sun has two jets rising off its poles. So that's your clue: those jets rise at right angles to something called the plane of the ecliptic."
