“Lieutenant,” Jeremy said, “can you dim our lights?”

“Dim them? Or shut them off?”

“Well, all the way off. But just flash them a few times.”

“Damn, look at that thing; it's got no symmetry at all, not bilateral or radial. It's just kind of there.”

“It's got a fractal pattern, though,” Richard pointed out. “The smaller whorls build to larger whorls and then larger ones. The whole thing looks like a giant toboggan if you squint at it.”

“How are you managing to squint, Dick?” Charlie shot back, drawing a laugh from Jeremy. The AI was right, though. It was as apt a description as the one that had come to Charlie, of water-worn driftwood. “You know what it reminds me of?”

“Coral,” Jeremy said promptly, and Dick said “Gypsum crystals, only curved.”

“Ready to flash lights.”

“Thank you, Lieutenant.” Charlie strained against his restraints to get a better look.

The sudden darkness in the
Gordon Lightfoot
, inside and out, was shocking. The cabin lights went out, followed—Charlie presumed, unable to see for himself—by the running lights lining her sides. Isolated in his suit, Charlie counted breaths, counted heartbeats. He could feel Richard and Leslie, feel Jeremy and Peterson in the cockpit of the shuttle, feel his suit and the trickle of cool air into his helmet, and none of it meant a thing beside the . . .
weight
of the shiptree, its presence, like an enormous silent breathing beast in the darkness alongside the fragile bubble of the
Gordon Lightfoot
.

The darkness lasted three heartbeats. Peterson flashed the shuttle's lights once, twice, a third time . . . and then left them on, and Charlie drew a single tremulous breath.

For a moment, the shiptree hung shimmering in space, silent and lovely, quiescent as a slumbering dragon. Until, without warning, the entire length of the strange curved hull went dark.

“Damn,” Jeremy said.

Peterson killed the lights of the shuttle again, before Charlie could suggest it. “I hope that thing doesn't move on me,” she murmured in a soft, strained voice. Charlie wouldn't be surprised if she hadn't meant to say it aloud. And then she whispered, “
Holy . . .
” as a dim sunlit glow irised into existence on the shiptree's hull, an aperture like a focusing eye.

“What the bloody hell is that?” said Jeremy, and Charlie grinned in the dark, because the glow illuminated a puff of vapor dispersing into darkness.

“It's an air lock,” Peterson said.

“It's an air lock,” Charlie echoed, a second later. “And the atmosphere inside has water vapor in it, and maybe carbon dioxide and oxygen. Would you look at that? Somebody lives in there, boys and girls. Somebody
lives in there
.”

“It's bloody beautiful,” Leslie commented from the speakers. The shiptree's lights winked back at them, blue and green and teal, and, with a sigh Charlie couldn't interpret, Peterson illuminated the shuttle.

“We can't dock,” she said.

“No. EVA. Safer, anyway, since we won't share any atmosphere with the shiptree that way, and we'll get a nice vacuum bath coming and going.”

“Is that wise?” Jeremy asked.

Charlie shrugged, even though Jeremy couldn't see it. “It's what we came here to do. And I think they just invited us in.”

Jeremy calibrated the atmospheric sampler while Charlie checked the swabs and plates in his test kit.
And if alien bugs don't like the taste of agar?

Then we assume they don't like the taste of people either.

Hah, Leslie.
On the other hand, it wasn't a half-bad point. There was no reason to think that an alien pathogen would find anything tasty about humans. And if it did . . . well, frankly, Charlie's nanosurgeons might protect him from any ill effects. Assuming anything got through the suit.
And in any scientific endeavor there is the element of risk.

He tapped Jeremy's arm, automatically bracing himself with a strap to account for the reaction. Jeremy looked up and hung the sampler on his belt. “Ready?”

“As I'll ever be.”

Charlie made sure his suit radio was live and said, “Lieutenant, we're moving out.”

“Copy.”

Together, they glided aft, toward the air lock.

Charlie went first. Peterson had matched velocities with the shiptree so evenly that he didn't need his attitude thrusters; he just checked the carabiner on the safety line clipped to Jeremy's suit, made sure the line was playing freely through the retractor, and jumped. There was no relative velocity between the
Gordon Lightfoot
and the alien vessel; Charlie sailed easily across the empty space and landed exactly where he'd aimed, with a firm grip on a whorl outlined in lime-green lights.

Up close, they looked exactly like firefly lights, but their texture—through the suit—was as hard as that of the surrounding hull. He stopped only half a second before he pressed the bubble of his helmet against the whorl.
That might not be wise, Charlie.

Not that wisdom had ever really been his strong point. “I'm over,” he told Jeremy. Unnecessarily, but Jeremy would wait for verbal confirmation anyway, in case his grip was no good.

“I'm on my way,” Jeremy replied. Charlie didn't turn his head to look, just firmed his grip on the hull and waited. A faint tug on the safety lines, a light shock of impact through the hull of the shiptree, and Jeremy was beside him. “First step's a lulu,” the linguist said.

“You aren't kidding. That air lock's big enough for two at a time, I think.”

“I don't like the idea of that. I'll go first,” Jeremy replied. “I have the atmosphere kit.”

“There's no atmosphere in there yet. And if the lock cycles with one of us inside and one of us out, we lose the safety lines. And possibly damage the air lock and piss off the natives.”

“You have a point.” There was a silence, and for a moment Charlie thought Jeremy was going to ask Richard's opinion. Or Wainwright's. Although the captain had been completely silent so far, Charlie had no illusions that she wasn't watching, breath held. She might look cool and reserved, but he knew a professional facade when he saw one. Charlie waited. Jeremy sighed over the radio and said, “All right, then. Side by side.”

They released their grips on the shiptree's hull on a count of three and kicked off lightly, shadows cast by the
Gordon Lightfoot
's floods expanding as they drifted back. Attitude jets reversed their trajectory and brought them in a looping half-arc,
swish
into the wide-open air lock like a free-throw basketball.

The shuttle's floods were arc-light white, the diffuse glow inside the shiptree the calm, friendly gold of late-afternoon sun. Charlie glanced around as he and Jeremy fetched up against the interior wall of the air lock. The blue-green bioluminescence didn't persist inside the hull. Here, instead, the curved bulkheads bowed together, chambered and knobbed like the inside of a turtle's shell, and each veined ridge glowed sunshine gold.

“Pretty,” Jeremy said. “That's not a color we get much in bioluminescence on Earth, is it?”

“No,” Charlie answered. “It looks like a full-spectrum light. I'm going to take some swabs of the walls. Where do you suppose the inside door is?”

“I think we'd better let the aliens handle cycling the air lock,” Jeremy answered, allowing himself to turn slowly at the end of his tether, scanning the walls of the vaguely spherical chamber. “I'd hate to purge the ship by accident, even if I could find the controls, and there's no guarantee they have anything like our concept of safety interlocks. Doesn't look as if they ever intended there to be gravity in this, does it?”

“No.” Charlie busied himself opening the plates and sterile swabs. “It'll take some time to culture these, of course. A week or ten days. And I guess we'll want to get some samples of this and that back to the
Montreal
to run through the mass spec.”

“Lieutenant Peterson, you'll run these back for us when we've got them ready?” Jeremy didn't need to change frequencies to speak to the shuttle, or the
Montreal
. Their entire conversation was on an open channel.

“That's why they sent me along, Dr. Kirkpatrick,” she answered. “As long as you're certain there's no danger.”

“Never say never,” Charlie quipped, stowing a swab in a sterile baggie and running his glove along the bulkhead. “I wonder if this feels as much like walnut paneling as it looks.”

“I wonder how it stands up to the extremes of cycling between space and the internal environment, if it's wood.”

“Nanosurgeons,” Charlie answered, more dryly than he'd intended. “Also, in the very least, the shiptree of Mars wasn't wood. Not exactly.”

“But enough like wood that you called it a tree—”

“What the heck else would you call it? Oh, hey.” As his gloves snagged on a rough patch. “There's something different here. A stained area, and the wood fibers are raised.”

“Diseased?”

“Maybe.” Charlie tugged his hand free, cautious of the suit's material. The area was a bit sticky, too, as if it were oozing sap. A bit of the bulkhead seemed to shift with his movement. “Ooops.”

“You're not a very reassuring person to explore an alien ship with, Charlie. What did you do?”

A shift in the quality of the light alerted him, a shadow falling across his back as the irising door cut the
Gordon Lightfoot
's floods. “Um. Triggered the air lock?”

“Dr. Forster? Dr. Kirkpatrick?” Peterson's voice, simultaneous with a Leslie-flavored burst of worry in the back of Charlie's brain.

“We're good in here,” he said, as the wall opposite began to unfurl from its central ridge like a flower bud spiraling open. “We seem to be allowed in . . .”

When the shiptree's atmosphere touched his suit, his helmet frosted over like a beer glass on a humid day. Jeremy cursed. “Can you see anything?”

“Not a thing.”

“Turn up your suit heaters,” Richard suggested. “Did you get the atmospheric sample?”

“As soon as I can read the dials, Dick.” Jeremy's tone absolved his words of irritation.

Charlie worked on clearing the surface of his helmet immediately in front of his face, curls of frost drifting from the creases of his suit and melting into jeweled droplets as they did. “I'd say there's some moisture in the atmosphere—”

“Hah.” A pause. “Eighty three percent humidity. Yeah, that's some. It's a warm room temperature in here.”

“Oxygen?”

“You could light a match, but you might scorch your fingers—let's put it that way. Lots of carbon dioxide, too. A little light on the nitrogen, heavy on the argon by our standards. This shows particulate matter, not to excess. Pollen or dust?”

“We'll know when we get the filters under a microscope,” Charlie said. Water beaded his faceplate, but he could see the open interior door clearly once he knocked it away. Drifting globules spattered against the air lock's walls, leaving behind a pattern of wet round dots that were rapidly absorbed. “If this is like the one on Mars, there will be a ladder type projection to use for traction when we get into the corridor.”

“Well, let's go see if they're waiting for us inside,” Jeremy said, checking the safety line before he reached out, flat-palmed the wall, and pushed himself toward the new opening. “I don't see any shadows.”

“Would you, in this light?”

“I don't—oh.” Jeremy reached out and caught one lip of the door in his right hand. Charlie drifted into his back, hard.

“Oof!”

“Shh.” Before Charlie could complain.

Charlie caught the other side of the doorway in his left hand and braced himself, and turned away from Jeremy and toward the interior of the shiptree. “Oh,” he said, blinking, trying to clear his eyes, and then realizing they didn't need clearing.

He and Jeremy had drifted into a jungle, emerging from a hole in the floor—essentially—to drift surrounded by twisted vines and heavy flowering branches thick with glossy leaves. The light glowed from the floor as well as overhead, and small creatures darted and called among the branches. Some of them had feathers or fur in jeweled colors; Charlie glimpsed something like a scarlet tanager with a snakelike neck. Animal voices rang through his helmet, shrillness muffled. Even damped by leaves and space suits the echoes made Charlie think they were in open space.

A hazy mist wound between the vines and branches, veils of silk that moved in response to air currents. “A zero-G rain forest,” Jeremy said.

“Cloud forest,” Charlie corrected automatically. “Well, I suppose it could ‘rain,' through some mechanism we're not seeing. Sprayers or something. But it looks like we're seeing plants watered by condensation, and frankly, if I
didn't
know that I don't know any of these species, I would think I was in Costa Rica. Look at all the pollinators and the insect eaters. They look just like hummingbirds and swifts. Convergent evolution. These critters brought their whole ecosystem with them.”

Jeremy glanced over at him, flash of teeth as he grinned behind his helmet. “I can hear the throb in your voice, Charlie.”
