"A jet," Tane said, "moving fast."

"More than one," Fatboy said. "Sounded like fighters."

"Oh c.r.a.p," Tane breathed. "It's already started."

As if to confirm his a.n.a.lysis, a sound of distant thunder rolled in from the north. Through the smashed window, the skies lit up with brilliant flashes.

"They're bombing the h.e.l.l out of something," Fatboy said.

"We're all out of time," Rebecca whispered. "We've got to get moving. We may already be too late."

"I'll get the Chronophone," Fatboy said. "Tane, find me a backpack of some kind to put it in. Rebecca, you've got to take the Jeep. Get to the Devonport Navy Base, find the submarine. I don't imagine it will be difficult to spot. Bring it across the harbor and we'll meet you down by the waterfront, at, say, the end of Princes Wharf. That's easy to find from the sea. On the way, try to raise Crowe on the radio."

"What about Mum?" Rebecca asked quietly.

"Take her with you. You can explain about her new home on the way."

Her new home. A little tin tube on the floor of the ocean.

Fatboy raced out to the Jeep to get the Chronophone and Rebecca disappeared upstairs.

Tane opened a few cupboards, trying to remember where he had seen Rebecca's schoolbag, a black backpack.

He had found it by the time Fatboy came in with the silver briefcase.

"Have we got time to run a test?" Tane asked.

"No. Where's Rebecca?"

"Still upstairs with her mum," Tane replied "Go and hurry them up. She's got to get moving."

Before he could move, he heard Rebecca's voice, shrieking from above them.

Tane bounded up the stairs and down the hallway to Rebecca's mother's room. The door was wide open.

The television was on. Helicopter camera shots showed the fog creeping over the top of the Albany hills. The view cut to the black silhouettes of warplanes streaking overhead, just visible in the moonlight, then back to the hillside. Ma.s.sive explosions rocked the camera, and the whole hillside shook in front of their eyes. Rivers of fire exploded in the treetops as breathless reporters tried to explain in voice-overs what was happening.

"Mum!" Rebecca shrieked once again. "You have to come with us. Now!"

"Don't be silly," her mother replied calmly, her eyes glued to the images of fire and fog. "This is the news. This is important."

Tane looked out the window. The sky to the north was ablaze, ma.s.sive tongues of flames leaping up into the black air from the conflagration on the ground. There were more flashes, more thunder, and he saw the silver flash of a jet caught for a second in the moonlight.

Rebecca turned to Tane in anguish. "She won't come!"

"I'll get Fatboy," Tane said calmly. "We'll carry her out."

Rebecca had one last try. "Mum, if you stay here, you will die!"

"Ssshh," her mum said irritably. "I can't hear what they're saying."

"I'll get Fatboy," Tane said again, turning to go.

"No." Rebecca's hand was on his arm. "No. We don't have the time."

Her legs seemed to be unsteady, and Tane put his arm around her shoulders to support her.

She slowly backed out of the room, one small footstep after another, her eyes never leaving her mother, washed in the soft light from the television set.

Tane, by her side, had no words of comfort.

Rebecca said again, her voice just starting to crack, "We don't have the time."

THE B BATTLE FOR A AUCKLAND Tane rode on the back of Fatboy's motorcycle with the cool night breeze on his face and the touch of Rebecca on his lips. of Fatboy's motorcycle with the cool night breeze on his face and the touch of Rebecca on his lips.

She had been strangely calm as they had come down the stairs from her mother's room. Strangely accepting.

Fatboy had given him the backpack containing the Chronophone and handed him a spare helmet, but before he could put it on, Rebecca had been in his arms, her hands around his neck.

She wasn't crying. In fact, she had seemed stronger, more determined than before. She had spoken quietly, her lips right next to his ear. "What I said this morning, about not knowing you, it wasn't true. I wanted to hurt you. I was angry."

After a moment's hesitation, Tane had put his hands on her arms.

He'd said, "You were right to be angry. I was stupid."

"You weren't stupid; you were hurt. I knew that and I should have accepted it."

Tane had started to say something, but she had put a finger on his lips to hush him.

She'd said, "I've known you all my life. I've always known you. I will always know you. But I'm not strong."

Tane began, "You're the strongest-"

She hushed him again and said, "I'm not strong. But you make me strong."

Then her lips had brushed in pa.s.sing against his, and the engine of the Jeep had roared and she was gone.

Tane had looked up a little guiltily at Fatboy, but there was no anger on his brother's face, just a quiet smile.

I will always know you.

For the first time, right then, it had occurred to Tane that he might never see her again.

The engine of the Harley gave its usual throaty chuckle, and Fatboy swerved in between two deserted cars and up the motorway on-ramp, heading toward the city.

The motorway was clogged with cars, all of them deserted. The owners, unable to go forward or backward, had simply left their vehicles and their belongings and either started walking south or had gone back to their homes.

Fatboy had to pick his path carefully. The cars ramming their way down the motorway had not kept in nice straight lanes but had zigged and zagged all over the road.

A couple of times they found themselves in a dead end in the maze of vehicles and had to get off and push the heavy bike backward in order to try a different route.

It was eleven o'clock by the time they made it as far as spaghetti junction-the main motorway interchange.

The going was easier after that. Most of the traffic was heading south. Heading back north into the city, there were fewer cars. Bigger gaps. They made good time up between the lines of abandoned vehicles.

Not entirely abandoned.

From more than a couple of cars, frightened faces stared out at them as they glided past. Either not knowing what to do or too afraid to do it, or both.

As they got closer, they could see several small fires burning in the city center.

Once they were off the motorway and into the city, the avalanche of abandoned cars disappeared. This was the northern side of the city. Anyone in their right minds was on the southern side, trying to get on the Southern Motorway.

As they came off the flyover onto Nelson Street, a gang of drunken youths in a brand-new Mercedes convertible swung out of the darkness and tried to sideswipe them.

A skinny kid standing up on the backseat threw a bottle at them, but it just shattered on the road behind them.

Fatboy calmly accelerated away from them, swerving around abandoned vehicles, the side pegs sc.r.a.ping on the ground. The Mercedes engine roared as it gave chase.

A bus was parked sideways across the road at the intersection with Victoria Street, and two cars were tangled together in a smash on the other side of it. Fatboy gunned the bike through the gap, and Tane heard a satisfying screech of brakes behind them as the driver of the Mercedes realized his car couldn't fit where the bike could.

A small block of shops was burning fiercely just across the road from the Skytower, the flames brighter than the surrounding streetlights, burning back the darkness of the central city street. Looters, or vandals, Tane thought. It seemed that antibodies and macrophages were not the only dangers in Auckland city this night.

Left unattended, the fire would quickly spread to nearby buildings, and the whole city center could soon be ablaze. A ma.s.sive funeral pyre for Auckland. But even as they swung around the corner by the entrance to the Skytower casino, they could see red flashing lights arriving from the opposite direction and a fire engine rolled smoothly to a stop in the middle of the road. It was a pumper, with a roof-mounted water nozzle. The crew quickly and efficiently set to work.

Fatboy pulled the Harley up outside the main doors to the casino. The huge gla.s.s doors were shut, and a quick shake by Tane ascertained that they were locked as well.

The casino never shut. But it was shut now. Inside, only the ma.s.sive water feature, a thin sheet of water cascading two stories down a sheer gla.s.s plate, showed any signs of life. The lights that never went out, were out. The gaming rooms above them were silent.

Tane got back on and Fatboy gunned the bike past the busy fire crew, around the corner, and down the concrete ramp into the underground car park.

The barrier arms were down, but the Harley squeezed past, just, and Fatboy kicked down the stand of the bike right outside the main elevators.

"We have to go up to the lobby," he said, "then down the escalator to the base of the Skytower itself."

"I hope the elevators are still working," Tane said.

And they were.

The radio produced nothing but static.

Manderson had said it was tuned to the right frequency, but when she pressed the CALL CALL b.u.t.ton and released it, all she got was a loud squawk. Had they knocked the frequency k.n.o.b somehow? She desperately tried every setting on the radio as she drove, her eyes flicking between the road and the radio. What she had to tell them would help; it might even turn the battle. But only if they had enough time to use the information. b.u.t.ton and released it, all she got was a loud squawk. Had they knocked the frequency k.n.o.b somehow? She desperately tried every setting on the radio as she drove, her eyes flicking between the road and the radio. What she had to tell them would help; it might even turn the battle. But only if they had enough time to use the information.

It was slow going. It wasn't far to the naval base, as the crow flies, and if she'd had a boat, she could have cut straight across the harbor and been there in a matter of minutes.

But traveling by road meant heading north and then cutting back east through Greenhithe and Albany. And that proved to be a circuitous maze of blocked roads.

She played with the k.n.o.bs on the radio as she maneuvered the Jeep through the constricted streets, and by the time she had reached the motorway overpa.s.s, she had managed to get through to the command center.

It was Manderson who answered the radio. "I thought I told you to hide away somewhere nice and deep," he drawled.

Rebecca stopped on the overpa.s.s and looked north toward the upper harbor highway. Along its length, Rebecca could see lights moving, vehicles, and soldiers with flashlights. There was no second line of defense. The line was just too long. It stretched from the beach at Mairangi Bay along through Albany and Greenhithe, all the way out to West Harbor.

If the line was breached, then Auckland was lost.

A flight of jets screamed just over her head, and the hillside in the distance, already blazing, flared like the sun for a brief second. A shock wave rattled the car windows a moment later. In that flash, though, she saw the reason for all the activity around her. The terror of Auckland.

In the flash of the incendiary bombs, she saw the long white cloud of the fog, stretching down the hillside, engulfing the North Harbor stadium and rolling forward toward them.

"I have to talk to Stony," she said urgently.

"He's busy," Manderson said. "If we don't stop this fog, or at least slow it down for a few hours, Auckland is going to become the biggest catastrophe the world has ever seen."

"I can help," Rebecca insisted.

"He really is too busy. We've had lab results come in on the chemical composition of the fog, so there's a lot of pressure to come up with some answers."

Rebecca could see that arguing was just going to waste a lot of time and produce no result. She said instead, "You can't shoot them. The...creatures."

"We know," Manderson said curtly.

"You can't shoot them and you can't blow them up."

"Not true. We've been knocking the stuffing out of those things for the last half hour. Claymore mines, rockets, mortars, you name it, we're chucking it at them."

"Hasn't stopped them coming, though, has it," Rebecca remarked.

"What are you saying?"

"You blow them up and the fog just reclaims them. They just get absorbed back, and the fog starts building another one. All you're doing is slowing them down."

There was a silence on the other end of the radio as Manderson thought about that. "You got a solution, or just a problem."

Rebecca said, "You need water, and lots of it. Water blasters. Fire hoses, if you can get them. They're soft. High-pressure water will cut right through them, and the water dissolves the material they're made of. It'll just run away into storm water drains and out into the ocean. That's the other thing. Salt. Spray salt, or even salt water on them and it alters the chemical structure of their bodies. Antib...the small ones as well as the big ones."

Manderson smiled and said, "You call them what you like. Are you sure about this?"

"Pretty much. Have you got any better suggestions?"
