Hollis had left with Billie in the morning, to look for the Humvees; working vehicles were in short supply, Olson had said, and if they had survived the explosion, they would be worth the hazards of such a trip. Whether Olson intended to keep them for his own use or return them, Peter did not know. This fact was left ambiguous, and Peter had elected not to press. After their experience in the van, the seven of them nearly cooked to death in the heat, and with Michael still unconscious, the wisest course seemed to be to say as little as they could. Olson had questioned them about the Colony and the purpose of their journey, and there was no avoiding offering some explanation. But Peter had volunteered only that they had come from a settlement in California and had gone looking for survivors. He told Olson nothing about the bunker, his silence suggesting that the place they came from was well armed. There would come a time, Peter thought, when he would probably have to tell Olson the truth, or at least more of it. But that time had not arrived yet, and Olson had appeared to accept the caginess of his explanation.

For the next two days they received only fleeting glimpses of the other inhabitants. Behind the huts stood the growing fields, with long irrigation pipes radiating from a central pumphouse, and beyond that the herd, several hundred head kept in large, shaded pens. From time to time they could see the boiling dust of a vehicle moving against the distant fence line. But apart from this, and a few figures in the fields, they detected virtually no one. Where were the other people? The doors to their huts were not locked, but always across the empty plaza were two men, wearing the orange jumpsuits. It was these men who brought them their meals, usually in the company of Billie or Olson, who reported on Michael’s condition. Michael appeared to have lapsed into a deep sleep—not a coma necessarily, Olson assured them, but something like one. They had seen it before, they said, the effects of the heat. But his fever was down, a good sign.

Then, the morning of the third day, Sara was returned to them.

She possessed no memory of what had happened to her. This part of the story that they related to Michael, when he awakened the following day, was not a lie, nor was Hollis’s tale of how he had found her. They were very happy and very relieved—Sara seemed fine, if a little slow to come around to the news of their new circumstances—but it was also true that both her capture and her return were deeply puzzling. Like the absence of lights and walls, it simply made no sense.
