Chapter 97

The Door

Five weeks after they left the cabin the first snow came to Basalt. Samantha drove up the Ruedi Overlook trail for a run. She loved running in the snow and was even happier she didn’t think of the mountains as a place to hide anymore.

The world had made it. Not finished — nobody was going to finish for years, and the list she had sent was still being worked down a truck at a time, a box on a pole, a controller in a basement, somebody driving out to a thing that could not take a new key and swapping it by hand. But the curve had bent. She checked it the way other people checked the weather, a public dashboard the Council put up, the count of rotated roots climbing every day, and it was climbing faster than anyone breaking them could keep up, which had been the whole bet. She let herself feel good about it, going up the hill in the snow.

But she was not going to pretend the other thing wasn’t also true. A hospital in a city she had never been to, and a person in it she would never meet, who had been on a machine that took a signed update she had made possible. She thought about it every day and knew the two were not going to cancel each other out. They were true at the same time. She held onto the irony that her quantum algorithm had caused that to be the case.

Vlad was somewhere being findable, watching doors, sending Eleanor the next one before it got hit. Marcus was on a plane somewhere convincing someone to do something. Eleanor had stood in front of the cameras on a Tuesday and said yes, keep going, and the world had believed her.

The three of them had saved it and did not agree about whether she should have done it the way she had.

She came over the top at the overlook and stopped, breathing hard, with the snow coming down into the valley. She finally let herself think about the thing she had told no one, that had sat at the edge of her head since before the cabin.

The reduction had a shape. She had always known its shape — it was hers, she had spent two years making it — and the shape did not stop where she had stopped it. It leaned. Past the keys, past the thing it broke, it went on leaning toward something she could see the edge of and could not yet reach, the way you can see a pass on the far ridge and know there is a whole country behind it you will not get to today.

There was more to it, but she hadn’t figured it out yet. Maybe she wouldn’t be able to. She knew that, but the path was visible and open. She hadn’t wanted it to be there, but it hadn’t gone away.

Her phone buzzed. It worked now; everyone’s did. While she was amused there was still no cell phone service in these mountains after all the tech bros’ promises, she was amused that the satellite text messaging worked.

It was from Vlad.

You are looking at it, the message said.

He didn’t have the reduction. He had never had it; she had made sure. But he had seen the shape of her work the way she had seen the shape of his flaw, from the outside, enough to know where it was headed. He had sent that message at the same moment she had let herself think about it again. She was sure, from the timing, that he felt it too — and sure, the same way, that he couldn’t reach it any more than she could.

Yes, she typed.

The three dots came and went and came again. He was deciding how much to say, out loud now, in front of her.

It would be bigger than this one, he wrote.

I know.

The last one cost us a lot.

I know that too.

She waited. The snow came down. Somewhere below her a plow was working the road to the dam, the sound of it coming up thin and far.

So, Vlad wrote. Just that. The straight man asking the only question there was. She had no answer for him. Yet.

Samantha looked at the far ridge for a while longer. Then she put the phone in her jacket without answering him. She turned and started down through the snow. The pass was still there behind her, and the whole country behind it, and it would wait as long as it took her to decide whether she dared go and look for it.
