“Thank God he wasn’t in with the reactors,” Quinn said. “I was going to say a big N-O to searching that.”

Edilio nodded agreement.

Little Pete was four years old, blond like his big sister, but freckled and almost girlish, he was so pretty. He didn’t look at all slow or stupid; in fact, if you didn’t know better, you’d have thought he was a normal, probably smart, kid.

But when Astrid hugged him, he seemed barely to notice. Only after almost a minute did he lift one hand from the video game control and touch her hair in an abstracted way.

“Have you had anything to eat?” Astrid asked. Then she revised the question. “Hungry?”

She had a particular way of talking to Little Pete when she wanted his attention. She held his face in her hands, carefully blocking his peripheral vision, half covering his ears. She put her face close to his and spoke calmly but with slow, careful enunciation.

“Hungry?” she repeated slowly but firmly.

Little Pete’s eyes flickered. He nodded yes.

“Okay,” Astrid said.

Edilio was inspecting the dated-looking electronics that covered most of one wall. He frowned and wrinkled his brow. “Everything looks like it’s normal,” he reported.

Quinn scoffed. “I’m sorry, are you a nuclear engineer as well as a golf cart driver?”

“I’m just looking at the readouts, man. I figure green is good, right?” He moved to a low, curved table supporting three computer monitors before three battered swivel chairs.

“I can’t even read this stuff,” Edilio admitted, peering closely at one monitor. “It’s all numbers and symbols.”

“I’m going to the break room to find some food for Petey,” Astrid announced. She started to move away, but Little Pete began to whimper. It was the sound a puppy makes when it wants something.

Astrid looked pleadingly at Sam. “Most of the time he doesn’t realize I’m around. I hate to leave him when he’s relating.”

“I’ll get the food.” Sam said. “What does he like?”

“Chocolate is never refused. He…” She started to say more but stopped herself.

“I’ll get him something,” Sam said.

Edilio had moved on to what seemed to be the most up-to-date piece of equipment in the room, a plasma screen mounted on the wall.

Quinn was looking up at the screen as well, rotating slowly in one of the engineer’s chairs. “See if you can get another channel, that one’s boring.”

“It’s a map,” Edilio said. “There’s Perdido Beach. There’s some little towns back in the hills. It goes all the way to San Luis.”

The map glowed pale blue, white, and pink, with a red bull’s-eye in the center.

“The pink is the fallout pattern in case there is ever a release,” Astrid said. “The red is the immediate area where the radiation would be intense. It gets data on wind patterns, the contours of the land, the jet stream, all that, and adjusts it.”

“The red and the pink, that’s the danger?” Edilio asked.

“Yes. That’s the plume where the fallout would be above acceptable levels.”

“That’s a lot of land,” Edilio said.

“But it’s weird,” Astrid said. She guided Little Pete to his feet and went closer to the map. “I’ve never seen it look like that. Usually the plume goes inland, you know, from the prevailing winds coming off the ocean. Sometimes the plume stretches all the way down to Santa Barbara. Or else up across the national park, depending on weather.”

The pink pattern was a perfect circle. The red zone was like a bull’s-eye inside that outer circle.

“The computer’s not getting satellite weather data,” Astrid said. “So it must have reverted to its default setting, which is this red circle with a ten-mile radius, and a pink circle with a hundred-mile radius.”

Sam peered at the map, unable at first to make sense of it. Then he began to locate the town, beaches he knew, other features.

“The whole town’s inside the red zone,” Sam said.

Astrid nodded.

“The red zone goes right to the far south end of town.”

“Yes.”

Sam glanced at her to discover whether she saw what he saw. “It runs right through Clifftop.”

“Yes,” she said slowly. “It does.”

“Are you thinking…”

“Yes,” Astrid said. “I’m thinking it’s a pretty amazing coincidence that the barrier seems to line up with the edge of the danger zone.” Then she added, “At least what we know of the barrier. We don’t know that it includes the entire red spot.”

“Does this mean there’s been some kind of radiation leak?”

Astrid shook her head. “I don’t think so. There’d be radiation alarms going off all over the place. But what’s weird is, it’s like cause and effect, only backward. The FAYZ is what cut off the weather data, which caused the computer to default. FAYZ first, then the map goes to default. So why would the FAYZ barrier be following a map whose lines it caused?”

Sam shook his head and smiled a little ruefully. “I must be tired. You lost me. I’ll go find some food.” He headed down the hall in the direction Astrid had indicated.

When he looked back she was standing, staring up at the map, a tight, grim expression on her face.
