Why would he think that? Nadia mouthed.

“So he keeps trying to talk me into leaving John and being with him, and John suspects that’s what he’s doing, so there’s a lot of jealousy between them. I’m just trying to keep them from each other’s throats, that’s all.”

Nadia decided to stick to her resolve and not ask about it again. But now she was involved despite herself. Maya kept coming to her to talk, and to ask her to convey messages to Frank for her. “I’m not a go-between!” Nadia kept protesting, but she kept doing it, and once or twice when she did she got into long conversations with Frank, about Maya of course; who she was, what she was like, why she acted the way she did. “Look,” Nadia said to him, “I can’t speak for Maya. I don’t know why she does what she does, you have to ask her yourself. But I can tell you, she comes out of the old Moscow Soviet culture, university and CP for both her mother and her grandmother. And men were the enemies for Maya’s babushka, and for her mother too, it was a matrioshka. Maya’s mother used to say to her, ‘Women are the roots, men are just the leaves.’ There was a whole culture of mistrust, manipulation, fear. That’s where Maya comes from. And at the same time we have this tradition of amicochonstvo, a kind of intense friendship where you learn the very tiniest details of your friend’s life, you invade each other’s lives in a sense, and of course that’s impossible and it has to end, usually badly.”

Frank was nodding at this description, recognizing something in it. Nadia sighed and went on. “These are the friendships that lead to love, and then love has the same sort of trouble only magnified, especially with all that fear at the bottom of it.”

And Frank — tall, dark, and somehow handsome, bulky with power, spinning with his own internal dynamo, the American politician (or so Nadia thought of him), now wrapped around the finger of a neurotic Russian beauty-Frank nodded humbly, and thanked her, looking discouraged. As well he should.

Nadia did her best to ignore all that. But it seemed everything else had turned problematic as well. Vlad had never approved of how much time they were spending on the surface in the daytime, and now he said, “We ought to stay under the hill most of the time, and bury all the labs as well. Outdoors work should be restricted to an hour in the early mornings and another in the late afternoons, when the sun is low.”

“I’ll be damned if I stay indoors all day,” Ann said, and many agreed with her.

“We’ve got a lot of work to do,” Frank pointed out.

“But most of it could be done by teleoperation,” Vlad said. “And it should be. What we are doing is the equivalent of standing ten kilometers from an atomic explosion-”

“So?” Ann said. “Soldiers did that-”

“-every six months,” Vlad finished, and stared at her. “Would you do that?”

Even Ann looked subdued. No ozone layer, no magnetic field to speak of; they were getting fried by radiation almost as badly as if they were in interplanetary space, to the tune of 5 rems per year.

And so Frank and Maya ordered them to ration their time outdoors. There was a lot of interior work to be done under the hill, getting the last row of chambers finished; and it was possible to dig some cellars below the vaults, giving them some more space protected from radiation. And many of the tractors were equipped to be teleoperated from indoor stations, their decision algorithms handling the details while the human operators watched screens below. So it could be done; but no one liked the life that resulted. Even Sax Russell, who was content to work indoors most of the time, looked a bit perplexed. In the evenings a number of people began to argue for immediate terraforming efforts, and they made the case with renewed intensity.

“That’s not our decision to make,” Frank told them sharply. “The UN decides that one. Besides it’s a long-term solution, on the scale of centuries at best. Don’t waste time talking about it!”

Ann said, “That’s all true, but I don’t want to waste my time down here in these caves, either. We should live our lives the way we want. We’re too old to worry about radiation.”

Arguments again, arguments that made Nadia feel as if she had floated off the good solid rock of her planet back into the tense weightless reality of the Ares. Carping, complaining, arguing; until people got bored, or tired, and went to sleep. Nadia started leaving the room whenever it began, looking for Hiroko and a chance to discuss something concrete. But it was hard to avoid these matters, to stop thinking about them.

Then one night Maya came to her crying. There was room in the permanent habitat for private talks, and Nadia went with her down to the northeast corner of the vaults, where they were still working on interiors, and sat by her arm to arm, shivering and listening to her, and occasionally putting an arm over her shoulder and giving her a hug. “Look,” Nadia said at one point, “why don’t you just decide? Why don’t you quit playing one off against the other?”

“But I have decided! It’s John I love, it’s always been John. But now he’s seen me with Frank and he thinks I’ve betrayed him. It’s really petty of him! They’re like brothers, they compete in everything, and this time it’s just a mistake!”

Nadia resisted learning the details, she didn’t want to hear it. She sat there listening anyway.

And then John was standing there before them. Nadia got up to leave, but he didn’t appear to notice: “Look,” he said to Maya. “I’m sorry, but I can’t help it. It’s over.”

“It’s not over,” Maya said, instantly composed. “I love you.”

John’s smile was rueful. “Yes. And I love you. But I want things simple.”

“It is simple!”

“No it isn’t. I mean, you can be in love with more than one person at the same time. Anyone can, that’s just the way it is. But you can only be loyal to one. And I want… I want to be loyal. To someone who is loyal to me. It’s simple, but…”

He shook his head; he couldn’t find the phrase. He walked back into the eastern row of chambers, disappeared through a door.

“Americans,” Maya said viciously. “Fucking children!” Then she was up through the door after him.

But soon she came back. He had retreated to a group in one of the lounges, and wouldn’t leave. “I’m tired,” Nadia tried to say, but Maya wouldn’t hear it, she was getting more and more upset. For over an hour they discussed it, over and over. Eventually Nadia agreed to go to John and ask him to come to Maya and talk it over. Nadia walked grimly through chambers, oblivious to the brick and the colorful nylon hangings. The go-between that nobody noticed. Couldn’t they get robots to do this? She found John, who apologized for ignoring her earlier. “I was upset, I’m sorry. I figured you’d hear it all eventually anyway.”

Nadia shrugged. “No problem. But look, you have to go talk to her. That’s the way it is with Maya. We talk, talk, talk; if you contract to be in a relationship, you have to talk your way all the way through it, and all the way out of it. If you don’t it will be worse for you in the long run, believe me.”

That got to him. Sobered, he went off to find her. Nadia went to bed.

The next day she was out working late on a trencher. It was the third job of the day, and the second had been trouble; Samantha had tried to carry a load on the earthmover blade while making a turn, and the thing had taken a nosedive and twisted the rods of the blade lifters out of their casings, spilling hydraulic fluid over the ground, where it had frozen before it even flattened out. They had had to set jacks under the airborne back end of the tractor, and then decouple the entire blade attachment and lower the vehicle on the jacks, and every step of the operation had been a pain.
