Jezzie didn’t answer—she frequently didn’t when Sinder turned loquacious. “I mean, I remember learning about it in school, but, man, who cared? Right? Photo-wuh? But I mean, it turns light into food. Light becomes energy becomes food and becomes energy again when we eat it. It’s like… You know…”

“It’s a miracle,” Orc rumbled.

“No,” Jezzie said, “it would be a miracle if it didn’t also work for weeds. Then it would be a miracle.” She’d found a root of something she didn’t like and was pulling on it, grunting with the effort.

“I could pull that for you,” Orc said.

“No, no, no!” both girls cried. “But thanks, Orc.”

Orc did not wear shoes, but if he had they’d probably have been size twenty. Extra, extra, extra wide. When he stepped into the garden things had a tendency to be crushed.

Sinder liked to get down low and look at her plants from close up. From one side she would see the miraculous leaves outlined against the backdrop of the lake and the marina area. From the other side she would see them almost like mounted specimens against the pearly gray blankness of the barrier.

Now she was looking at the feathery structure of a carrot top against the blank black of the stain. It had the odd effect of making the leaf seem like a work of abstract art.

She looked up from the plant and saw the stain suddenly shoot upward. What had been a ragged, undulating wave of black extending only a dozen or so feet above her head blossomed like one of her charges to become a terrible black bloom thirty, fifty, a hundred feet high before it slowed and stopped.

She hoped Jezzie hadn’t seen it. But when her friend stood up there were tears running down her cheeks.

“I feel bad inside,” Jezzie said simply.

Sinder nodded. She glanced at Orc, but he was absorbed in reading. “Me, too, Jez. Like…” She didn’t have the words for what it was like. So she just shook her head.

Jezzie wiped dirt from her brow and managed to actually transfer more dirt there. She was looking down toward the marina. Sinder followed her gaze and saw Sam and Astrid holding each other close on the top deck of the White Houseboat.

Jezzie said, “At first when I heard she was back I thought it was a good thing. I thought Sam would be happy. You know: he’s been lonely.”

It was a fact of life in the FAYZ that kids cut off from TMZ and Facebook and the ins and outs of Hollywood and reality shows focused much of their gossip hunger on the closest thing they had to celebrities: Sam, who most people liked and everyone worried about; Diana, who most people didn’t like but whose baby everyone worried about; the baby itself, in particular betting about its gender and possible powers; news of Caine from Perdido Beach; affectionate speculation about Edilio and the nature of his friendship with the Artful Roger; theories about Astrid with passionate disagreement as to whether she was a good person and good for Sam, or alternately a sort of Jadis, the White Witch from Narnia; and, of course, the whispered-about, much-speculated-about relationship (or lack of same) between Brianna and Jack and/or Brianna and Dekka.

Remarks about Sam’s state of mind were no more unusual than speculation about Lindsay Lohan or Justin Bieber had once been. Except that every person at the lake felt his or her own fate was all too closely tied to Sam Temple.

“He doesn’t look good,” Jezzie said. Sam was a tiny, distant figure from where she stood. And Sinder might have pointed that out on some other day. But the truth was that something about the way Sam held Astrid was wrong.

Sinder looked out across her garden, the plants she knew as individuals, many with names she and Jezzie had given them. And she saw the line of stain push slowly now, slowly but relentlessly, toward the sky.

Drake found the light almost unbearable. The setting sun stabbed his eyes with jagged pain. How long since he had seen the sun? Weeks? Months?

There was no time down in the gaiaphage’s lair, no rising or setting moon, no mealtime, bath time, wake-up time.

The coyotes were waiting for him in the ghost town below the mine entrance. Pack Leader—well, the current Pack Leader, if not the original—licked a scab on his right front paw.

“Take me to the lake,” Drake said.

Pack Leader stared at him with yellow eyes. “Pack hungry.”

“Too bad. Take me.”

Pack Leader bared his teeth. The coyotes of the FAYZ were not the runts that coyotes had been back before the FAYZ. They weren’t as big as wolves, but they were big. But it was easy to see that they were not well. Their fur was mangy. There were bare patches on all of them where scraped gray-and-red flesh showed through. Their eyes were dull. Their heads hung low and the tails dragged.

“Humans take all prey,” Pack Leader said. “Darkness says don’t kill humans. Darkness does not feed pack.”

Drake frowned and counted the pack. He saw seven, all adults, no pups.

As if reading Drake’s mind, Pack Leader said, “Many die. Killed by Bright Hands. Killed by Swift Girl. No prey. No food for pack. Pack serves Darkness and pack goes hungry.”

Drake barked out a disbelieving laugh. “Are you bitching out the gaiaphage? I’ll whip the skin off you!”

Drake unwrapped his tentacle arm, which had been wound around his torso.

Pack Leader retreated a few dozen feet. The pack might be weak with hunger but they were still far too quick for Drake to catch. He felt uneasy. The gaiaphage would not listen to excuses. Drake had a mission. He had been to the lake before, but never alone. He knew he could follow the barrier, but the barrier itself was a long way off. If he wandered around lost he might be spotted. The success of his mission lay in stealth and surprise.
