Phytosphere

“Do you understand what trespass means?”

“The human sense of it is slightly different than the Tarsalan one. And there is no concept or word for property in any of our languages.” The word property popped out in English. “Or in our various cultures. But it is a concept that is obviously deeply ingrained on Earth.”

“Then let me give you some advice… Tarsalan.” She hit the word hard. “Get off my property before I kill you.”

She lifted the Montclair and pointed it straight at him. He shifted, took a step backward, and his pupils shrank to such a small size that she could hardly see them.

“My child, shoot me if you wish…but you have already signed your own death writ. We outnumber you more than a hundred to one. What can you possibly do to stop us?”

And Glenda realized that, yes, they weren’t really so smart after all.

She watched them go. She felt sorry for them. The Cameron Chess Study was one thing, and Tarsalans might win against humans again and again in a situation where all the moves were circumscribed by game rules— indeed, all the negotiations with the Tarsalans had possessed a gamelike quality, and she remembered how all of Kafis’s actions seemed to be predicated on a kind of rarefied and arcane games theory—but there were no rules when it came to war, especially human war. There was only brutality.

She waited for Fernandes to get back, then told him her plan. “Let’s get the kerosene. Jake, help us.”

They went into the cave’s second chamber and retrieved five big cans of kerosene, a primitive fuel that Lenny had had the foresight to stash away “For when our batteries fail.” The wind was strong, though it changed direction often, and would act like a bellows. The forest was tinder-dry and would go up like a torch. Eight hundred and seventy thousand acres, all of it dead, providing the necessary combustibles to make her own firestorm.

They poured the fuel in great ribbons of vaporous liquid, venturing into the forest, down the hill, up the hill, until they had dumped every last ounce of kerosene into the brush. Then Glenda got the box of safety matches, scratched one along the side, and, keeping it shielded from the wind with her hand, lit the nearest bush. The flames ignited with a voracious ripple, and spread so fast she hardly had time to leap back.

Ten seconds, twenty seconds, thirty seconds, and the size of the conflagration grew alarmingly. Tongues of flame leaped yards into the air; she took glory in how bright everything was. She could see ! The glow of the fire bathed her eyes with soul-refreshing illumination. All four kids looked on in fascination. She knew that somewhere out there in the dead forest the Tarsalans looked on as well. She thought they were feeling dread in their hearts, and that they were oozing the thick, musty odor they oozed whenever they were terrified.

The heat of the fire became too much for Glenda, Fernandes, and the kids, and they retreated into the cave, where it was cool and damp, and where a faint wind blew up from the bowels of the Earth, forcing smoke away from the cave entrance.

There they stayed as the firestorm raged around them. Glenda wasn’t without guile when it came to the Tarsalans. Maybe they had an ingenious way of putting out the fire. Maybe they would just get in their TLVs and take off. Some ash drifted in through the cave entrance and landed on her foot. Then again, maybe, as with the attack on the mothership, and ultimately on the phytosphere control device itself, they would be caught unawares. They would see this fire, and they would get another lesson in how humans behaved, especially when they had nothing left to lose.

The following day Gerry and Ian eased away from the Phobos-Deimos Terminal, and Ian established a transit orbit toward Earth. He engaged thrusters three and one. The singularity drives showed no malfunction and Ian risked full power.

Four days later, the Earth-Moon system hove into view over the craggy nose of Gaspra. The phytosphere was a festering green cancer around Gerry’s home planet, thicker than he had ever seen it, and he momentarily wondered if it would be enough—the shift of the Moon two thousand miles closer to Earth—but then decided it would, knew that he couldn’t have been wrong in his calculations.

For a brief while, as they got closer, an automated Tarsalan probe, egg-shaped like most of the alien craft and wrapped in its own shimmering plasma of blue, violet, and pink light, orbited the asteroid, but the PCV’s scans told them it was unweaponized, unmanned, and posed no threat.

“I’m sure they’ve exhausted all their military capability by this time,” said Ian. “Looks like we’re home free, buddy.”

All that needed to be done now was fire Drive Five. This would initiate the slight change of angle needed for the final impact, and bring Gaspra crashing into the lunar surface.

But when Ian tried the modified key box, it was as if the alien virus had at last worked through to his initial fix and he got no response from thrust conduit number five. In other words, the drive that had given them their initial trouble previous to mission countdown was again flickering into the red. Ian maneuvered from his seat over to the navigation console and his fingers clicked over the keys, but he couldn’t regain command of the conduit, nor secure access through some creative rerouting.

He worked frantically on the problem for the next five minutes. Gerry glanced nervously out the big freighter windows and saw the Earth, like a rotting wedge of lime, and the Moon, craters now fully visible.

“So there’s no way to fix the problem?” asked Gerry, because in these most harrowing moments he had no choice but to defer to Ian.

Ian now had full schematics on screen four. The left side of the screen showed diagrams, while text filled the right side—script so tiny Ian had to tap his contact lenses to their strongest setting.

Ian didn’t so much read as skim. He ignored Gerry as he went through the thick, turgid prose of the drive specs, the sweat beading on his shaved head and a thick vein sticking out like a blue worm over his temple. All the while their speed increased.

“I know these specs like the back of my own hand,” he said. “But you never know. Maybe if I review it, something could jog and I might…”

Gerry felt helpless, frustrated, and so anxious to solve the problem that he kept fidgeting in his seat.

“Couldn’t we go to the drive itself and do something to fix it?”

Ian froze. He stopped flicking through the script and turned to Gerry. He looked like a man on a spirit quest who had just experienced the revelation he had been looking for, his blue eyes wide, his lower lip coming out, his ears shifting a fraction on the sides of his head. Gerry thought he had only pointed out the obvious, but Ian looked at him as if he were Moses coming down from the mount.

“You’re a genius, Gerry.” Then he swung to the timer up on the console. “We’ve got to move. We’ve got only a certain envelope to do this and, after that, it’s a no go for good.”

“What are you going to do?”

“I’m going to blow Drive Five sky-high. I don’t know why I didn’t think of it before. Am I ever glad you’re on this mission. The resulting explosion will give us the necessary thrust to angle us into a collision trajectory. As I say, I know the specs inside out and I think this can work. Especially because all we have to do is collide with your so-called wide region of effectiveness.”

“You’re going to blow up the drive?”

“Yes.”

“How are you going to do that?”

“I’m going to sled to the drive, crawl into its access bay, and manually cross the male and female thrust conduits so they reverse on each other and blow the singularity to pieces.” He motioned at the screen of schematics. “I can’t believe I was looking at a technical solution when all I really needed was the PCV’s fire ax. You’re brilliant, Gerry.”

“But…you’re going to blow up the drive?”

“Right.”

“And then what?”

Ian frowned. “I already told you. The blast should give us the necessary thrust to make it all happen.”
