"Why not? I am."

A couple of members of the hatch gang had heard this and laughed. They were lounging next to the big wooden doors, awaiting any order to open them. Hayden nodded and they reluctantly abandoned their cards to man the winch wheel.

"Hang on there!" Both Hayden and Martor turned.The eccentric armorer, Mahallan, was poised at an inside doorway. Her silhouette was very interesting, but she only perched there a moment before flying over to the hatch. "You boys going for a night flight?"

Hayden shrugged. "All flights are night flights right now."

"Hmm. Glad to see you've overcome your fear of winter," she said to Martor. The boy blushed and stammered something.

"Listen," continued Mahallan, "I'd like you to do something for me. While you're out there—I know it'll be dark so you probably won't see them—if you spot anything like this, could you bring it back?" She opened her fist to reveal a bent little glittering thing, like a chrome wasp.

Martor leaned close. "What's that?" Hayden plucked it from the air and turned it so its wings rainbowed in the gaslight. "I've seen these before," he mused. "But I don't know what they are. They're not alive."

"Not by ordinary standards, no," said Mahallan. She was perched on his bike, an angel in silhouette; rearing back she said with some obscure sense of satisfaction, "They're tankers."

Martor smiled weakly. "Ha?"

"Tankers. That little abdomen is an empty container. Usually when you catch one and open it, you'll find the tank full of ugly chemicals like lithium pentafluorophenyl borate etherate, medioxyphenyl-boronic acid or naphthylboronic acid. Very interesting. And where do you suppose they're taking it?"

"Couldn't tell ya," said Martor, whose eyes had gone very wide as the multisyllabic chemical names tripped off Mahallan's lips.

"They're going in," said the armorer. "Toward Candesce." She snatched the metal wasp out of the air. "Find me some more. If you can."

"Yes, ma'am." Martor saluted and turned to Hayden. "Let's get goin', then."

The hatch gang spun their wheel and the bike door opened into total darkness. As Mahallan kicked away to presumably return to her little workshop, Hayden leaned in to Martor and whispered, "You forgot the passenger saddle. It's over there." He pointed.

"Ah. Uh, thanks."

Mahallan left, and Hayden waited for Martor to back out of his impulse to come along. But he returned with the saddle and dutifully waited while Hayden strapped it to the side of the bike. And he climbed aboard meekly and waited while Hayden guided the fan-jet to the open hatch and shoved it out into the light breeze, following himself a second later.

"IT'S NOT COLD at all!" Martor squinted over his shoulder as Hayden opened the throttle a bit. They shot away from the Rook. The bike was admirably quiet, so Hayden was able to lean back and say, "Like I said, the clouds trap the heat."

Now that they were in winter, the ships of the expeditionary force had all their lights on. Distant clouds made a tunnel that curled away ahead of them, but the air was clear for miles around. It was an opportunity to open up the ships' throttles that their pilots were stolidly ignoring. True, they were making twenty or thirty miles per hour, but each could do five times that without straining.

"Shall we see what she'll do?" Hayden asked. He didn't wait for Martor's answer, but gripped the throttle and twisted it.The fan-jets grumble became a roar and they shot ahead and into the full blaze of the Rook's headlamp.

Martor pounded him on the back. "Quit showin' off!"

Hayden laughed. "No! Look back!"

Martor turned awkwardly and gasped. Hayden knew that their corkscrew contrail would be gleaming in the cone of the Rook's headlight like a thread of fire.

"Come on, Martor. Let's do some stitching!"

The bike was capable of nearly two hundred miles an hour, and he tested it to this limit over the next few minutes, running lines back and forth parallel to the Rook's course. Laying down parallel lines like this was called stitching. Following his own contrail was the safest way to test the bike's speed; if he entered cloud or deviated too far from air he knew was clear, he could kill himself and Martor if he ran into something unseen.

Hunkered down behind the windscreen, he could nonetheless feel the rip of the air inches away, and cautioned Martor not to stick his head—or hands or feet—out lest he get them ripped off. The bike performed well and he quickly got a feel for it.

"Right!" he said eventually. "Let's do a bit of exploring." He eased back on the throttle and nosed them in the direction of the encircling clouds. As they were about to enter a huge puffball he turned the bike and hit the throttle again; the ground wire trailing behind them whipped ahead into the cloud, and sparks flew.

"Is this a good idea?" Martor had been whooping with delight a minute before. He seemed afraid of anything new, Hayden mused.

"It's a great idea." Now that they'd shed their static potential, it was safe to push the bike into the cloud, a transition noticeable only in the drop in temperature and sudden appearance of the cone of radiance from the bike's headlight. Hayden glanced back; the Rook was invisible already.

Martor shook Hayden's shoulder. "H-how are we going to find me ship again?"

"Like this." He reached down and shut off the engine. As the whine faded, he heard a distant grumble—the other ships—but it seemed to be coming from all around them at once. "Wait for it."

The foghorn's note sounded low and sonorous through the darkness. "Where did that come from?" he asked Martor.

"That way?" The boy pointed.

"Right. Now, we're not going far. I just want to see if there's another side to these clouds." He spun up the bike again.

The mist seemed to go on forever, an empty silver void. After a few minutes, though, Hayden began to see pearl-like beads gleaming in the headlight. They shot by on either side, and at their lower speed Martor was able to reach out and grab one. It splashed into a million drops in his hand.

The water spheres grew more numerous and larger. "Could they stall the engine?" asked Martor nervously.

"A big one could," he replied. "Like that one." He dodged the bike around a quivering ball the size of his head.

Visibility was improving. They were now idling their way through a galaxy of turning, shivering drops, some of them tiny, some big as men. Reflections and refractions from the bike's headlamp lit the water cloud in millions of iridescent arcs and glints.

Martor was silent. Hayden looked back at him; the boy's jaw was slack as he gaped at the sight.

"Look." Hayden cut the engine and with the last of their momentum steered them over to a water-beaded stone that hung in solitary majesty amid the water. The rock was less than two feet in diameter.

"Well?" he said to Martor. "Aren't you going to claim this piece of land for Slipstream?"

The boy laughed and reached up to grab the stone. "Not like that!" Keeping one hand on the bike, Hayden flipped himself out of the saddle and wrapped his legs around the rock. "You've got to sit on a piece of land to claim it, you know.

"I decree this land the property," he said, "of…" Aerie.

"Of Hayden Griffin!" shouted Martor.

"Okay. Of the sovereign state of Hayden. Uck, it's wet." He kicked it away and settled into a perch on the windscreen of the bike.

"I didn't know it was like this out here," said Martor. "I grew up in Rush."

"What are you doing here, anyway? You're—" He was about to say "just a boy" but figured Martor would resent mat. "—not a volunteer."

"Press-ganged," said Martor with a shrug. "I don't mind. It was that or the orphanage. I been in the fleet a year now, but this is the first time I've been out of dock."
