Michael was lying in the back of a pickup, covered with a plastic tarp. The bed of the truck was full of rattling pipes. Billie had told him to lie still, not to make a sound, but the jumpy feeling inside him was almost more than he could bear. What was she doing, giving him a concoction like that and expecting him to lie perfectly still? The effect was like shine in reverse, as if every cell in his body were singing a single note. Like his mind had passed through some kind of filter, giving each thought a bright, humming clarity.

No more dreams, she’d said. No more fat lady with her smoke and smell and awful, scratchy voice. How did Billie know about his dreams?

They’d stopped once, just a few moments after they’d left the infirmary, which they’d exited through the rear. Some kind of checkpoint. Michael heard a voice he didn’t recognize, asking Billie where she was going. From under the tarp Michael had listened anxiously to their exchange.

“There’s a broken line out in the eastern field,” she explained. “Olson asked me to move these pipes around for the crew tomorrow.”

“It’s new moon. You shouldn’t be out here.”

New moon, Michael thought. What was so important about the new moon?

“Look, that’s what he said. Take it up with him if you want.”

“I don’t see how you’re going to make it back in time.”

“Let me worry about that. Are you going to let me through or not?”

A tense silence. Then: “Just be back by dark.”

Now, sometime later, Michael felt the truck slowing once again. He drew the tarp aside. A purpling evening sky and behind them, in the truck’s wake, a boiling cloud of dust. The mountains were a distant bulge against the horizon.

“You can come out now.”

Billie was standing at the tailgate. Michael climbed from the truck bed, grateful to move at last. They had parked outside a massive metal shed, at least two hundred meters long, with a bulging convex roof. He saw the rusted shape of fuel tanks behind it. The land was lined with railroad tracks, heading off in all directions.

A small door opened in the side of the building; a man emerged and walked toward them. His skin was covered in grease and oil, so much that his face was practically black with it; he was holding something in his hands, working at it with a filthy rag. He stopped where they were standing and looked Michael up and down. A short-barreled shotgun was holstered to his leg. Michael remembered him as the driver of the van that had brought them from Las Vegas.

“This him?”

Billie nodded.
