Blue Mars. Kim Stanley Robinson

which snaked overhead in long amorphous lines that revealed the tent’s ventilation patterns. Alarms were ringing everywhere, loud in the still-thick air, and shards of clear framework plastic were scattered on the green grass of the street. Ann stumbled past a body curled just like the figures modelled in ash in Pompeii. Arsiaview was narrow but long, and it was not obvious where she should go. The whoosh of rocket-launchers led her eastward toward the Socket, the magnet of the madness – like a monopole, discharging Earth’s insanity onto them.

      There might be a plan revealed here; the cable’s defences seemed to be capable of handling the Reds’ lightweight missiles, but if the attackers thoroughly destroyed Sheffield and the Socket, then there would be nothing for UNTA to come down to, and so it would not matter if the cable remained swinging overhead. It was a plan that mirrored the one used to deal with Burroughs.

      But it was a bad plan. Burroughs was down in the lowlands, where there was an atmosphere, where people could live outside, at least for a while. Sheffield was high, and so they were back in the past, back in ’61 when a broken tent meant the end for everyone in it exposed to the elements. At the same time most of Sheffield was underground, in many stacked floors against the wall of the caldera. Undoubtedly most of the population had retreated down there, and if the fighting tried to follow them it would be impossible, a nightmare. But up on the surface where fighting was possible, people were exposed to fire from the cable above. No, it wouldn’t work. It wasn’t even possible to see what was happening. There were more explosions near the Socket, static over the intercom, isolated words as the receiver caught bits of other coded frequencies cycling through: ’—taken ArsiaviewpM/cfc/c/c—’ ‘We need the AI back but I’d say X axis three two two, Y axis eightpkkkkk—’

      Then another barrage of missiles must have been launched at the cable, for overhead Ann caught sight of an ascending line of brilliant explosions of light, no sound to them at all; but after that, big black fragments rained down on the tents around her, crashing through the invisible fabrics or smashing onto the invisible framework, then falling the last distance onto the buildings like the dropped masses of wrecked vehicles, loud despite the thin air and the intervening tents, the ground vibrating and jerking under her feet. It went on for minutes, with the fragments falling farther outward all the time, and any second in all those minutes could have brought death down on her. She stood looking up at the dark sky, and waited it out.

      Things stopped falling. She had been holding her breath, and she breathed. Peter had the Red code, and so she called his number and tapped in a patch attempt, heard only static. But as she was turning down the volume in her earphones, she caught some garbled half-phrases – Peter, describing Red movements to Green forces, or perhaps even to UNTA. Who could then fire rockets from the cable defence systems down onto them. Yes, that was Peter’s voice, bits of it all cut with static. Calling the shots. Then it was only static.

      At the base of the elevator brief flashes of explosive light transformed the lower part of the cable from black to silver, then back to black again. Every alarm inside Arsiaview began ringing or howling. All the smoke whipped away toward the east end of the tent. Ann got into a north-south alley and leaned back against the east wall of a building, flat against concrete. No windows on the alley. Booms, crashes, wind. Then the silence of near airlessness.

      She got up and wandered through the tent. Where did one go when people were being killed? Find your friends if you can. If you can tell who they are.

      She collected herself and continued looking for Kasei’s group, going to where Dao had said they would be, and then trying to think where they would go next. Outside the city was a possibility; but having come inside they might try for the next tent to the east, try to take them one by one, decompress them, force everyone below and then move on. She stayed on the street paralleling the tent wall, jogging along as fast as she could. She was in good shape but this was ridiculous, she couldn’t catch her breath, and she was soaking the inside of her suit with sweat. The street was deserted, eerily silent and still, so that it was hard to believe she was in the middle of a battle, and impossible to believe she would ever find the group for which she was looking.

      But there they were. Up ahead, in the streets around one of the triangular parks – figures in helmets and suits, carrying automatic weapons and mobile missile-launchers, firing at unseen opponents in a building fronted with chert. The red circles on their arms, Reds—

      A blinding flash and she was knocked down. Her ears roared. She was at the foot of a building, pressed against its polished stone side. Jaspilite: red jasper and iron oxide, in alternating bands. Pretty. Her back and bottom and shoulder hurt, and her elbow. But nothing was agonizing. She could move. She crawled around, looked back up to the triangle park. Things were burning in the wind, the flames little oxygen-starved orange spurts, going out already. The figures there were cast about like broken dolls, limbs akimbo, in positions no bones could hold. She got up and ran to the nearest knot of them, drawn by a familiar grey-haired head that had come free of its helmet. That was Kasei, only son of John Boone and Hiroko Ai, one side of his jaw bloody, his eyes open and sightless. He had taken her too seriously. And his opponents not seriously enough. His pink stone eye-tooth lay there exposed by his wound, and seeing it Ann choked and turned away. The waste. All three of them dead now.

      She turned back and crouched, undipped Kasei’s wristpad. It was likely that he had a direct access band to the Kakaze, and when she was back in the shelter of an obsidian building marred by great white shatter-stars, she tapped in the general call code, and said, ‘This is Ann Clayborne, calling all Reds. All Reds. Listen, this is Ann Clayborne. The attack on Sheffield has failed. Kasei is dead, along with a lot of others. More attacks here won’t work. They’ll cause the full UNTA security force to come back down onto the planet again.’ She wanted to say how stupid the plan had been in the first place, but she choked back the words. ‘Those of you who can, get off the mountain. Everyone in Sheffield, get back to the west and get out of the city, and off the mountain. This is Ann Clayborne.’

      Several acknowledgements came in, and she half-listened to them as she walked west, back through Arsiaview toward her rover. She made no attempt to hide; if she was killed she was killed, but now she didn’t believe it would happen; she walked under the wings of some dark covering angel, who kept her from death no matter what happened, forcing her to witness the deaths of all the people she knew and all the planet she loved. Her fate. Yes; there was Dao and his crew, all dead right where she had left them, lying in pools of their own blood. She must have just missed it.

      And there, down a broad boulevard with a line of linden trees in its centre, was another knot of bodies – not Reds – they wore green headbands, and one of them looked like Peter, it was his back – she walked over weak-kneed, under a compulsion, as in a nightmare, and stood over the body and finally circled it. But it was not Peter. Some tall young native with shoulders like Peter’s, poor thing. A man who would have lived a thousand years.

      She moved on carelessly. She came to her little rover without incident, got in and drove to the train terminal at the west end of Sheffield. There a piste ran down the south slope of Pavonis, into the saddle between Pavonis and Arsia. Seeing it, she conceived a plan, very simple and basic, but workable because of that. She got on the Kakaze band and made her recommendations as though they were orders. Run away, disappear. Go down into South Saddle, then around Arsia on the western slope above the snowline, there to slip into the upper end of Aganippe Fossa, a long straight canyon that contained a hidden Red refuge, a cliff dwelling in the northern wall. There they could hide and hide and start another long underground campaign, against the new masters of the planet. UNOMA, UNTA, metanat, Dorsa Brevia – they were all Green.

      She tried calling Coyote, and was somewhat surprised when he answered. He was somewhere in Sheffield as well, she could tell; lucky to be alive no doubt, a bitter furious expression on his cracked face.

      Ann told him her plan; he nodded.

      ‘After a time they’ll need to get farther away,’ he said.

      Ann couldn’t help it: ‘It was stupid to attack the cable!’

      ‘I know,’ Coyote said wearily.

      ‘Didn’t you try to talk them out of it?’

      ‘I
