Green Mars. Kim Stanley Robinson

they descend into madness and chaos. You remember my words here, this is a prophecy as true as truth.”

      “That isn’t what John Boone said,” Jackie declared. She spent many of her evening hours exploring John Boone’s AI, and now she pulled out the box from her thigh pocket, and with only the briefest search for a passage, the friendly voice from the box was saying, “Mars will never be truly safe until Earth is too.”

      Coyote laughed raucously. “Yes, well, John Boone was like that, wasn’t he? But you note he is dead, while I’m still here.”

      “Anyone can hide,” Jackie said sharply. “But John Boone got out there and led. That’s why I’m a Boonean.”

      “You’re a Boone and a Boonean!” Coyote exclaimed, teasing her. “And Boonean algebra never did add up. But look here, girl, you have to understand your grandfather better than that if you want to call yourself a Boonean. You can’t make John Boone into any kind of dogma and be true to what he was. I see other so-called Booneans out there doing just that, and it makes me laugh when it doesn’t make me foam at the mouth. Why if John Boone were to meet you and talk to you for even just an hour, then at the end of that time he would be a Jackie-ist. And if he met Dao and talked to him, then he would become a Daoist, maybe even a Maoist. That’s just the way he was. And that was good you see, because what it did was put the responsibility for thinking back onto us. It forced us to make a contribution, because without that Boone couldn’t operate. His point was not just that everyone can do it, but that everyone should do it.”

      “Including all the people on Earth,” Jackie replied.

      “Not another quick one!” Coyote cried. “Oh you girl, why don’t you leave these boys of yours and marry me now, I got a kiss like this vacuum pump, here, come on,” and he waved the pump at her and Jackie knocked it aside and shoved him back and ran, just for the fun of the chase. She was now the fastest runner in Zygote bar none—even Nirgal with all his endurance could not sprint the way she did—and the kids laughed at Coyote as he skipped after her; he was pretty swift himself for an ancient, and he turned and jinked and went after them all, growling and ending up at the bottom of a pile-on, crying, “Oh my leg, oh, I’m going to get you for that—you boys are just jealous of me because I’m going to steal your girl away, oh! Stop! Oh!”

      This kind of teasing made Nirgal uncomfortable, and Hiroko didn’t like it either. She told Coyote to stop, but he just laughed at her. “You’re the one that’s gone and made yourself a little incest camp,” he said. “What are you going to do, neuter them?” He laughed at Hiroko’s dark expression. “You’re going to have to farm them out soon, that’s what you’re going to have to do. And I might as well get some of them.”

      Hiroko dismissed him, and soon after that he was off on a trip again. And the next time Hiroko taught, she took all the kids to the bathhouse and they got in the bath after her and sat on the slick tiles in the shallow end, soaking in the hot steamy water while Hiroko spoke. Nirgal sat next to Jackie’s long-limbed naked body which he knew so well, including all its dramatic changes of the past year, and he found that he was unable to look at her.

      His ancient naked mother said, “You know how genetics works, I’ve taught you that myself. And you know that many of you are half brothers and sisters, uncles and nieces and cousins and so forth. I am mother or grandmother to many of you, and so you should not mate and have children together. It’s as simple as that, a very simple genetic law.” She held up a palm, as if to say, This is our shared body.

      “But all living things are filled with viriditas,” she went on, “the green force, patterning outward. And so it is normal that you will love each other, especially now that your bodies are blooming. There is nothing wrong with that, no matter what Coyote says. He is only joking in any case. And in one thing he is right; you will soon be meeting many other people your age, and they will eventually become mates and partners and co-parents with you, closer to you even than your tribe kin, whom you know too well to ever love as an other. We here are all pieces of your self; and true love is always for the other.”

      Nirgal kept his eyes on his mother’s, his gaze blank. Still he knew exactly when Jackie had brought her legs together, he had felt the minute change in temperature in the water swirling between them. And it seemed to him that his mother was wrong in some of what she had said. Although he knew Jackie’s body so well, she was still in most ways as distant as any fiery star, bright and imperious in the sky. She was the queen of their little band, and could crush him with a glance if she cared to, and did fairly often even though he had been studying her moods all his life. That was as much otherness as he cared to handle. And he loved her, he knew he did. But she didn’t love him back, not in the same way. Nor did she love Dao in that way, he thought, at least not any more; which was a small comfort. It was Peter she watched in the way that he watched her. But Peter was away most of the time. So she loved no one in Zygote the way Nirgal loved her. Perhaps for her it was already as Hiroko had said, and Dao and Nirgal and the rest were simply too well known. Her brothers and sisters, no matter the genes involved.

      Then one day the sky fell in earnest. The whole highest part of the water ice sheet cracked away from the CO₂, collapsing through the mesh and into the lake and all over the beach and the surrounding dunes. Luckily it happened in the early morning when no one was down there, but in the village the first booms and cracks were explosively loud, and everyone rushed to their windows and saw most of the fall: the giant white sections of ice dropping like bombs or spinning down like skipped plates, and then the whole surface of the lake exploding and spilling out over the dunes. People came charging out of their rooms, and in the noise and panic Hiroko and Maya herded the kids into the school, which had a discrete air system. When a few minutes had passed and it appeared that the dome itself was going to hold, Peter and Michel and Nadia ran off through the debris, dodging and jumping over the shattered white plates, around the lake to the Rickover to make sure it was all right. If it weren’t it would be a deadly mission for the three of them, and mortal danger to everyone else. From the school window Nirgal could see the far shore of the lake, which was cluttered with icebergs. The air was aswirl with screaming gulls. The three figures twisted along the narrow high path just under the edge of the dome, and disappeared into the Rickover. Jackie chewed her knuckles in fear. Soon they phoned back a report: all was well. The ice over the reactor was supported by a particularly close-meshed framework, and it had held.

      So they were safe, for the moment. But over the next couple of days, spent in the village in an unhappy state of tension, an investigation into the cause of the fall revealed that the whole mass of dry ice over them had sagged ever so slightly, cracking the layer of water ice and sending it down through the mesh. Sublimation on the surface of the cap was apparently speeding up to a remarkable degree.

      During the next week the icebergs in the lake slowly melted, but the plates scattered over the dunes were still there, melting ever so slowly. The youngsters weren’t allowed on the beach any more: it wasn’t clear how stable the remainder of the ice layer was.

      The tenth night after the collapse they had a village meeting in the dining hall, all two hundred of them. Nirgal looked around at them, at his little tribe; the sansei looked frightened, the nisei defiant, the issei stunned. The old ones had lived in Zygote for fourteen Martian years, and no doubt it was hard for them to remember any other life; impossible for the children, who had never known anything else.

      It did not need saying that they would not surrender themselves to the surface world. And yet the dome was becoming untenable, and they were too large a group to impose themselves on any of the other hidden sanctuaries. Splitting up would solve that problem, but it wasn’t a happy solution.

      It took an hour’s talk to lay all this out. “We could try Vishniac,” Michel said. “It’s big, and they’d welcome us.”

      But it was the Bogdanovists’ home, not theirs. This was the message on the faces of the old ones. Suddenly it seemed to Nirgal that they were the most frightened of all.

      He said, “You could move further back under the ice.”

      Everyone stared at him.

      “Melt
