They drove past the ruins of a mobile home. Emery's car was out of sight. Robbie looked at his cellphone and saw there was no signal. In the back, Tyler stirred.

"Hey Rob, where are we?"

"We're here. Wherever here is. The island."

"Sweet." Tyler leaned over the seat to jostle Zach awake. "Hey, get up. "

Robbie peered through the overgrown greenery, looking for something resembling a beach house. He tried to remember which hurricane had pounded this part of the coast, and how long ago. Two years? Five?

The place looked as though it had been abandoned for decades. Fallen palmettos were everywhere, their leaves stiff and reddish-brown, like rusted blades. Some remained upright, their crowns lopped off. Acid-green lizards sunned themselves in driveways where ferns poked through the blacktop. The remains of carports and decks dangled above piles of timber and mold-blackened sheetrock. Now and then an intact house appeared within the jungle of flowering vines.

But no people, no cars except for an SUV crushed beneath a toppled utility pole. The only store was a modest grocery with a brick facade and shattered windows, through which the ghostly outlines of aisles and displays could still be glimpsed.

"It's like 28 Days 28 Days," said Zach, and shot a baleful look at his father.

Robbie shrugged. "Talk to the man from the Starfleet Academy."

He pulled down a rutted drive to where the hybrid sat beneath a thriving palmetto. Driftwood edged a path that led to an old wood-frame house raised on stiltlike pilings. Stands of blooming cactus surrounded it, and trees choked with honeysuckle. The patchy lawn was covered with hundreds of conch sh.e.l.ls arranged in concentric circles and spirals. On the deck a tattered red whirligig spun in the breeze, and rope hammocks hung like flaccid coc.o.o.ns.

"I'm sleeping there," said Tyler.

Leonard gazed at the house with an unreadable expression. Emery had already sprinted up the uneven steps to what Robbie a.s.sumed was the front door. When he reached the top, he bent to pick up a square of coconut matting, retrieved something from beneath it then straightened, grinning.

"Come on!" he shouted, turning to unlock the door; and the others raced to join him.

The house had linoleum floors, sifted with a fine layer of sand, and mismatched furniture-rattan chairs, couches covered with faded barkcloth cushions, a canvas seat that hung from the ceiling by a chain and groaned alarmingly whenever the boys sat in it. The sea breeze stirred dusty white curtains at the windows. Anoles skittered across the floor, and Tyler fled shouting from the outdoor shower, where he'd seen a black widow spider. The electricity worked, but there was no air conditioning and no television; no internet.

"This is what you get for three hundred bucks in the off season," said Emery when Tyler complained.

"I don't get it." Robbie stood on the deck, staring across the empty road to where the dunes stretched, tufted with th.o.r.n.y greenery. "Even if there was a hurricane-this is practically oceanfront, all of it. Where is everybody?"

"Who can afford to build anything?" said Leonard. "Come on, I want to get my stuff inside before it heats up."

Leonard commandeered the master bedroom. He installed his laptop, Emery's camera equipment, piles of storyboards, the box that contained the miniature Bellerophon Bellerophon. This formidable array took up every inch of floor s.p.a.ce, as well as the surface of a ping-pong table.

"Why is there a ping-pong table in the bedroom?" asked Robbie as he set down a tripod.

Emery shrugged. "You might ask, why is there not a ping-pong table in all bedrooms?"

"We're going to the beach," announced Zach.

Robbie kicked off his shoes and followed them, across the deserted road and down a path that wound through a miniature wilderness of cactus and bristly vines. He felt lightheaded from lack of sleep, and also from the beer he'd snagged from one of the cases Emery had brought. The sand was already hot; twice he had to stop and pluck sharp spurs from his bare feet. A horned toad darted across the path, and a skink with a blue tongue. His son's voice came to him, laughing, and the sound of waves on the sh.o.r.e.

Atop the last dune small yellow roses grew in a thick carpet, their soapy fragrance mingling with the salt breeze. Robbie bent to pluck a handful of petals and tossed them into the air.

"It's not a bad place to fly, is it?"

He turned and saw Emery, shirtless. He handed Robbie a bottle of Tecate with a slice of lime jammed in its neck, raised his own beer and took a sip.

"It's beautiful." Robbie squeezed the lime into his beer, then drank. "But that model. It won't fly."

"I know." Emery stared to where Zach and Tyler leaped in the shallow water, sending up rainbow spray as they splashed each other. "But it's a good excuse for a vacation, isn't it?"

"It is," replied Robbie, and slid down the dune to join the boys.

Over the next few days, they fell into an odd, almost sleepless rhythm, staying up till two or three A.M., drinking and talking. The adults pretended not to notice when the boys slipped a Tecate from the fridge, and ignored the incense-scented smoke that drifted from the deck after they stumbled off to bed. Everyone woke shortly after dawn, even the boys. Blinding sunlight slanted through the worn curtains. On the deck where Zack and Tyler huddled inside their hammocks, a treefrog made a sound like rusty hinges. No one slept enough, everyone drank too much.

For once it didn't matter. Robbie's hangovers dissolved as he waded into water warm as blood, then floated on his back and watched pelicans skim above him. Afterward he'd carry equipment from the house to the dunes, where Emery had created a shelter from old canvas deck chairs and bedsheets. The boys helped, the three of them lugging tripods and digital cameras, the box that contained Leonard's model of the Bellerophon Bellerophon, a cooler filled with beer and Red Bull.

That left Emery in charge of household duties. He'd found an ancient red wagon half-buried in the dunes, and used this to transport bags of tortilla chips and a cooler filled with Tecate and limes. There was no store on the island save the abandoned wreck they'd pa.s.sed when they first arrived. No gas station, and the historical society building appeared to be long gone.

But while driving around, Emery discovered a roadside stand that sold homemade salsa in mason jars and sage-green eggs in recycled cardboard cartons. The drive beside it was blocked with a barbed-wire fence and a sign that said BEWARE OF TWO-HEADED DOG.

"You ever see it?" asked Tyler.

"Nope. I never saw anyone except an alligator." Emery opened a beer. "And it was big enough to eat a two-headed dog."

By Thursday morning, they'd carted everything from one end of the island to the other, waiting with increasing impatience as Leonard climbed up and down dunes and stared broodingly at the blue horizon.

"How will you know which is the right one?" asked Robbie.

Leonard shook his head. "I don't know. Maggie said she thought it would be around here-"

He swept his arm out, encompa.s.sing a high ridge of sand that crested above the beach like a frozen wave. Below, Tyler and Zach argued over whose turn it was to haul everything uphill again. Robbie shoved his sungla.s.ses against his nose.

"This beach has probably been washed away a hundred times since McCauley was here. Maybe we should just choose a place at random. Pick the highest dune or something."

"Yeah, I know." Leonard sighed. "This is probably our best choice, here."

He stood and for a long time gazed at the sky. Finally he turned and walked down to join the boys.

"We'll do it here," he said brusquely, and headed back to the house.

Late that afternoon they made a bonfire on the beach. The day had ended gray and much cooler than it had been, the sun swallowed in a haze of bruise-tinged cloud. Robbie waded into the shallow water, feeling with his toes for conch sh.e.l.ls. Beside the fire, Zach came across a shark's tooth the size of a guitar pick.

"That's probably a million years old," said Tyler enviously.

"Almost as old as Dad," said Zach.

Robbie flopped down beside Leonard. "It's so weird," he said, shaking sand from a conch. "There's a whole string of these islands, but I haven't seen a boat the whole time we've been here."

"Are you complaining?" said Leonard.

"No. Just, don't you think it's weird?"

"Maybe." Leonard tossed his cigarette into the fire.

"I want to stay." Zack rolled onto his back and watched as sparks flew among the first stars. "Dad? Why can't we just stay here?"

Robbie took a long pull from his beer. "I have to get back to work. And you guys have school."

"f.u.c.k school," said Zach and Tyler.

"Listen." The boys fell silent as Leonard glared at them. "Tomorrow morning I want to set everything up. We'll shoot before the wind picks up too much. I'll have the rest of the day to edit. Then we pack and head to Fayetteville on Sat.u.r.day. We'll find some cheap place to stay, and drive home on Sunday."

The boys groaned. Emery sighed. "Back to the salt mines. I gotta call that guy about the show."

"I want to have a few hours with Maggie." Leonard pulled at the silver skull in his ear. "I told the nurse I'd be there Sat.u.r.day before noon."

"We'll have to leave pretty early," said Emery.

For a few minutes n.o.body spoke. Wind rattled brush in the dunes behind them. The bonfire leaped, then subsided, and Zach fed it a knot of driftwood. An unseen bird gave a piping cry that was joined by another, then another, until their plaintive voices momentarily drowned out the soft rush of waves.

Robbie gazed into the darkening water. In his hand, the conch sh.e.l.l felt warm and silken as skin.

"Look, Dad," said Zach. "Bats."

Robbie leaned back to see black shapes dodging sparks above their heads.

"Nice," he said, his voice thick from drink.

"Well." Leonard stood and lit another cigarette. "I'm going to bed."

"Me too," said Zach.

Robbie watched with mild surprise as the boys clambered to their feet, yawning. Emery removed a beer from the cooler, handed it to Robbie.

"Keep an eye on the fire, compadre," he said, and followed the others.

Robbie turned to study the dying blaze. Ghostly runnels of green and blue ran along the driftwood branch. Salt, Leonard had explained to the boys, though Robbie wondered if that was true. How did Leonard know all this stuff? He frowned, picked up a handful of sand and tossed it at the feeble blaze, which promptly sank into sullen embers.

Robbie swore under his breath. He finished his beer, stood and walked unsteadily toward the water. The clouds obscured the moon, though there was a faint umber glow reflected in the distant waves. He stared at the horizon, searching in vain for some sign of life, lights from a cruiseship or plane; turned and gazed up and down the length of the beach.

Nothing. Even the bonfire had died. He stood on tiptoe and tried to peer past the high dune, to where the beach house stood within the grove of palmettos.

Night swallowed everything, He turned back to the waves licking at his bare feet. Something stung his face, blown sand or maybe a gnat. He waved to disperse it, then froze.

In the water, plumes of light coiled and unfolded, dazzling him. Deepest violet, a fiery emerald that stabbed his eyes; cobalt and a pure blaze of scarlet. He shook his head, edging backward; caught himself and looked around.

He was alone. He turned back, and the lights were still there, just below the surface, furling and unfurling to some secret rhythm.

Like a machine, he thought; some kind of underwater windfarm. A wave-farm?

But no, that was crazy. He rubbed his cheeks, trying to sober up. He'd seen something like this in Ocean City late one night-it was something alive, Leonard had explained, plankton or jellyfish, one of those things that glowed. They'd gotten high and raced into the Atlantic to watch pale-green streamers trail them as they body-surfed.

Now he took a deep breath and waded in, kicking at the waves, then halted to see if he'd churned up a luminous cloud.

Darkness lapped almost to his knees: there was no telltale glow where he'd stirred the water. But a few yards away, the lights continued to turn in upon themselves beneath the surface: scores of fist-sized nebulae, soundless and steady as his own pulse.

He stared until his head ached, trying to get a fix on them. The lights weren't diffuse, like phosph.o.r.escence. And they didn't float like jellyfish. They seemed to be rooted in place, near enough for him to touch.

Yet his eyes couldn't focus: the harder he tried, the more the lights seemed to shift, like an optical illusion or some dizzying computer game.

He stood there for five minutes, maybe longer. Nothing changed. He started to back away, slowly, finally turned and stumbled across the sand, stopping every few steps to glance over his shoulder. The lights were still there, though now he saw them only as a soft yellowish glow.

He ran the rest of the way to the house. There were no lights on, no music or laughter.

But he could smell cigarette smoke, and traced it to the deck where Leonard stood beside the rail.

"Leonard!" Robbie drew alongside him, then glanced around for the boys.

"They slept inside," said Leonard. "Too cold."

"Listen, you have to see something. On the beach-these lights. Not on the beach, in the water." He grabbed Leonard's arm. "Like-just come on."

Leonard shook him off angrily. "You're drunk."

"I'm not drunk! Or, okay, maybe I am, a little. But I'm not kidding. Look-"

He pointed past the sea of palmettos, past the dunes, toward the dark line of waves. The yellow glow was now spangled with silver. It spread across the water, narrowing as it faded toward the horizon, like a wavering path.

Leonard stared, then turned to Robbie in disbelief. "You idiot. It's the f.u.c.king moon."

Robbie looked up. And yes, there was the quarter-moon, a blaze of gold between gaps in the cloud.

"That's not it." He knew he sounded not just drunk but desperate. "It was in in the water-" the water-"

"Bioluminescence." Leonard sighed and tossed his cigarette, then headed for the door. "Go to bed, Robbie."

Robbie started to yell after him, but caught himself and leaned against the rail. His head throbbed. Phantom blots of light swam across his vision. He felt dizzy, and on the verge of tears.

He closed his eyes; forced himself to breathe slowly, to channel the pulsing in his head into the memory of spectral whirlpools, a miniature galaxy blossoming beneath the water. After a minute he looked out again, but saw nothing save the blades of palmetto leaves etched against the moonlit sky.

He woke several hours later on the couch, feeling as though an axe were embedded in his forehead. Gray light washed across the floor. It was cold; he reached fruitlessly for a blanket, groaned and sat up.

Emery was in the open kitchen, washing something in the sink. He glanced at Robbie, then hefted a coffee pot. "Ready for this?"

Robbie nodded, and Emery handed him a steaming mug. "What time is it?'

"Eight, a little after. The boys are with Leonard-they went out about an hour ago. It looks like rain, which kind of throws a monkey wrench into everything. Maybe it'll hold off long enough to get that thing off the ground."

Robbie sipped his coffee. "Seventeen seconds. He could just throw it into the air."

"Yeah, I thought of that too. So what happened to you last night?"
