Judy fired again, aiming toward the tree this time, but it didn’t even hesitate. She couldn’t tell if she’d hit it or not, but even if she miraculously struck a vital organ with a third shot, momentum would carry it as far as it needed to go now.
She didn’t waste time trying. “Jump!” she shouted. She dropped the pistol and lunged for Tippet, sweeping him inside as gently as she could, then she slammed the hatches closed and shouted again: “Jump!”
“We’re not—” Allen began, but the tank lurched violently to the side. Judy whacked her head against the hyperdrive, lost her balance, and fell toward the beanbag chair, but she never connected. The tank lurched again, and they were in free fall.
The sudden flash of sunlight on the side of the tank nearly blinded her, but when she squinted she could see pitch-black shadows crisscrossing the yellow wall in every direction. The creak of plastic stretching to its limit made her think at first that they were stress lines about to give way, but then she realized what it was: the shadows of tree branches.
“Tippet?” she called softly. “Tippet, are you all right?”
There was no answer. Debris was rising into the air all through the tank, but none of it looked like a butterfly in a spacesuit. She raised both feet and looked at the soles of her shoes, but she hadn’t stepped on him. Where had he gone?
There was a scrabbling sound, then a heavy thump. The shadows moved across the plastic, their thick ends going for the dark side of the tank.
“Holy shit,” Judy said. “It’s still alive.” Either she hadn’t hit it, or a bullet in the trunk didn’t matter. And apparently neither did vacuum.
“It can’t be,” Allen said. “The jump field wasn’t set nearly wide enough. We must have cut it in half.”
“Then what’s that outside?”
“Just—I don’t know. Muscle contractions.” He looked at his video monitor, and Judy followed his glance, but the image was spinning wildly. The tree must have knocked the camera loose.
Something soft smacked her in the face. She reached up to brush it away, stopping just in time when she realized it was Tippet. “There you are! Are you okay?”
He flapped his wings a couple of times to keep himself in place, but still said nothing. Then Judy realized why: his walkie-talkie was on the other side of the hatch, no doubt tumbling away into space.
“Just a sec,” she said, digging among her things for the other unit. She found it still beside the water bucket and flipped it on.
Tippet’s voice immediately filled the tank. “Let’s not do that again.”
“What’s the matter? Are you hurt?”
“I… don’t believe so. Not now. But the jump cut me off from the overmind, and I was terrified until they located my signal again.”
“Oh.” She had no idea how that would feel, but it didn’t sound fun.
The tank screeched again as tree branches slid across its rough exterior, then something started banging rhythmically on the side right next to Judy’s head. More muscle contractions? She looked at her video monitor, then at her spacesuit, still crumpled up on what had a minute ago been the floor. “First things first,” she said. “Suit up.”
“Uh… right,” said Allen.
“Tippet, can that suit of yours stand up to vacuum?”
“In an emergency,” he said.
“If whatever it’s banging on the outside of this thing manages to punch through, I guarantee you it’ll be an emergency.”
Judy wasn’t wearing her suit liner, but she didn’t want to take the time to put it on, either. She just pulled on the bottom half of her outersuit, wriggled into the top, locked the waist ring, then put on the communications carrier and the helmet and gloves. She sealed it up tight this time, and made Allen do the same.
“Testing, testing. Allen? Tippet, can you hear me?” she asked.
“Loud and clear,” Allen replied.
“Tippet?”
Nothing.
“Tippet?” She looked around for him, saw him gently flapping his wings to keep himself from drifting into the way of their flailing arms and legs.
“Tippet, can you hear me?”
“There you are,” he said. “I had to find your intercom frequency.”
“Oh. Sorry. I should have thought of that.”
She turned on her monitor. Her camera was still taped down; she zoomed out to extreme wide angle and swiveled it around until she could see what they’d dragged into space with them.
It was the whole tree. Either the jump field was wider than Allen had thought, or the tree had been reaching down to grab them when he hit the escape button, but Judy couldn’t see any missing limbs. It clung to the Getaway with its gnarly, tubular roots, and its trunk was bent nearly double, shoving the green fronds at the end of its branches down into the tank’s shadow. The whole works was rotating slowly, about twice the speed of a second hand on a clock, and the tree kept shifting around to keep its fronds in darkness. It kept one root free to whack against the side of the tank.
“Jesus,” Judy whispered. “It’s definitely alive. And it doesn’t like direct sunlight.”
Allen slapped his gloved hand against the side of the tank.
“What are you doing?” Judy asked him.
“Answering.” He whacked the tank twice more, then paused, then three times.
She laughed, more from nerves than anything. “Oh, come on. You can’t honestly expect a tree to do fill-in-the-blank math problems. Especially while it’s hanging on for dear life in interplanetary space.”
Then the tank rang with four distinct blows. They were muffled inside the sealed spacesuits, but still clearly audible.
Allen whacked the wall five times.
Judy counted the response: one, two, three, four, five…
If there was a sixth, they never heard it. Above-normal atmospheric pressure from inside and the stress of a tree gripping it from outside was too much for even a lifetime-guaranteed septic tank to withstand. The end seam right next to Judy peeled open like a zipper, and in a single whoosh like a fighter jet passing low overhead, all their air rushed out into space.
Everything that wasn’t tied down also raced toward the crack. Judy watched her sleeping bag slither out like an oil slick down a drain, followed by her spacesuit liner, the pistol, and half a dozen smaller items. The stuff sack full of food wedged itself up against it, but wouldn’t fit through.
Tippet, on the other hand, sailed out with room to spare.
“Tippet!” Judy yelled.
“Tptkpk!” The radio hissed and popped with words in his his native tongue, then he said, “I—I’m all right. I caught a branch.”
“Thank God,” she said.
Tippet said, “Ha. I had thought the notion of a deity rather quaint when I found it among the words in your language, but in this instance I will thank anyone I can.”
“Can you make it back in?”
“I believe so. Just don’t do anything to alarm the tree.”
Judy couldn’t imagine anything alarming it more than it already was, but she said, “We won’t.”
With no air to carry sound, the tank was totally silent now. Judy’s spacesuit hissed softly as it bled off air to put its internal pressure within its design limits, but that soon stopped. She put her hand against the wall, but she couldn’t feel any vibration from the tree, either. The outrushing air had acted like a rocket, setting tank, tree, and all spinning a full revolution every five or six seconds; centrifugal force had probably stretched the tree out to full height again, and it didn’t want to risk slipping just to whack on the tank with a root.
The tree was heavier than the Getaway; the center of gravity was somewhere outside, partway up its trunk. Judy and Allen and all their loose gear had drifted up against one wall, and the short radius of their spin kept threatening to give her vertigo when she turned her head too quickly. Steam boiled out of the water bucket and the open beer cans. Water in vacuum would boil until it froze. And the nitrogen in Judy’s and Allen’s blood would boil, too, under the reduced pressure in their suits.
“We’re going to get the bends,” she said. “We’ve got to land.”
Allen shook his head. “We can’t do that with a tree hanging on to us. It’s got to weigh at least a ton. Even if we deployed both ’chutes, we’d still hit like a bomb.”
She looked at the monitor. Sure enough, the tree was standing out to its full height. It wasn’t moving anymore, either. She could see Tippet out near the end of one of the branches, slowly working his way back. However inadvertently, the tree had saved his life. But it could still cost her and Allen theirs. “Then we’ll have to cut it loose,” she said.
“No,” Tippet said.
“I know it sounds cruel, but the tree’s going to die anyway,” she said. “It’s probably as good as dead already, and even if it’s not, we can’t put it back. And we can’t keep full atmospheric pressure in these suits, which means we’ve got maybe half an hour at best before we start getting embolisms in our blood. When one of them plugs an artery in our hearts or our brains, we’re dead.”
“There is another option.”
“What?”
“Go for my starship instead.”
Neither Judy nor Allen said anything for a second, then they both spoke at once. “Can we breathe your air?” Judy asked, while Allen said, “It would take too long to match velocities.”
Tippet actually laughed; not the “Ha, ha, ha” he’d used before, but the real thing. It was an obvious mixture of Allen’s and Judy’s laughter, but it sounded genuine. “Yes, you can breathe our air. From what you’ve told me of Earth’s atmosphere, ours is closer to normal for you than what you’ve been breathing here. And Allen, you forget what you are dealing with. Our starship has engines enough to boost us to a third of lightspeed. We can accelerate to match your vector, while you use the planet’s gravity to bring yours closer to ours. Within a few minutes at most, we will be able to dock and bring you on board.”
“But do you have any space that’s big enough for us to stay?” Judy asked.
Tippet laughed again. “We are aerial creatures. Of course we do.”
