“Oh no. Of course not. We’re much freer than that. Mothering can be any kind of thing. Sometimes mothers are nothing but incubators.”

“I suppose so — ”

“Take my word for it.”

“… But Jackie cried.”

On they hiked, in silence. Like a lot of the big craters, Moreux turned out to have several pie-wedge watersheds, converging on a central marsh and lake. In this case the lake was small and kidney-shaped, curving around the rough low knobs of a central peak complex. Zo and Russell came out from under the forest canopy on an indistinct trail that faded into elephant grass, and they would have gotten quickly lost except for the stream, which was oxbowing through the grass toward a meadow and then the marshy lake. Even the meadow was dominated by elephant grass, great circular clumps of it that stood well overhead, so that they often had a view of nothing but giant grasses and sky.

The long blades of grass gleamed under the lilac midday zenith. Russell stumbled along well behind Zo, his round sunglasses like mirrors in his face, reflecting the grass bundles as he looked this way and that. He appeared utterly foxed, amazed at the surroundings, and he muttered into an old wristpad that hung on his wrist like a manacle.

A final oxbow into the lake had created a fine sand-and-pebble beach, and after testing with a stick for quicksand at the waterline, and finding the sand firm, Zo stripped off her sweaty singlet and walked out into the water, which got nice and cold a few meters offshore. She dove under, swam around, hit her head on the bottom. There was a beached boulder standing over some deep water, and she climbed it and dove in three or four times, doing a forward flip in the water right after entry; this forward somersault, difficult and graceless in the air, caused a quick little tug of weightless pleasure in the pit of her stomach, a feeling as close to orgasm as any nonorgasm she had ever felt. So she dove several times, until the sensation wore off and she was cooled. Then she walked out of the lake and lay on the sand, feeling its heat and the solar radiation cook both sides of her. A real orgasm would have been perfect, but despite the fact that she was laid out before him like a map of sex, Russell sat cross-legged in the shallows, absorbed apparently by the mud, naked himself except for sunglasses and wristpad. A farmer-tanned little bald wizened primate, like her image of Gandhi or Homo habilis. It was even a bit sexy how different he was, so ancient and small, like the male of some turtle-without-a-shell species. She pulled her knee to the side and shifted up her bottom in an unmistakable present posture, the sunlight hot on her exposed vulva.

“What amazing mud,” he said, staring at the glop in his hand. “I’ve never seen anything like this biome.”

“No.”

“Do you like it?”

“This biome? I suppose so. It’s a bit hot and overgrown, but interesting. It makes a change.”

“So you don’t object. You’re not a Red.”

“A Red?” She laughed. “No, I’m a whig.”

He thought that one over. “Do you mean to say that greens and Reds are no longer a contemporary political division?”

She gestured at the elephant grass and saal trees backing the meadow. “How could they be?”

“Very interesting.” He cleared his throat. “When you go to Uranus, will you invite a friend of mine?”

“Maybe,” Zo said, and shifted her hips back a bit.

He took the hint, and after a moment leaned forward and began to massage the thigh nearest him. It felt like a monkey’s little hands on her skin, clever and knowing. He could lose his whole hand in her pubic hair, a phenomenon he appeared to like, as he repeated it several times and got an erection, which she held hard as she came. It was not like being tabled, of course, but any orgasm was a good thing, especially out in the sun’s hot rain. And although his handling of her was basic, he did not exhibit any of that hankering for simultaneous affection which so many of the old ones had, a sentimentality which interfered with the much more acute pleasures that could be achieved one person at a time. So when her shuddering had stilled she rolled on her side, and took his erection in her mouth — like a little finger she could wrap her tongue entirely around — while giving him a good view of her body. She stopped once to look herself, big rich taut curves, and saw that the span of her hips stood nearly as high as his shoulders. Then back to it, vagina dentata, so absurd those frightened patriarchal myths, teeth were entirely superfluous, did a python need teeth, did a rock stamp need teeth? Just grab the poor creatures by the cock and squeeze till they whimpered, and what were they going to do? They could try to stay out of the grip, but at the same time it was the place they most wanted to be, so that they wandered in the pathetic confusion and denial of that double bind — and put themselves at the risk of teeth anyway, any chance they got; she nipped at him, to remind him of his situation; then let him come. Men were so lucky they weren’t telepathic.

Afterward they took another dip in the lake, and back on the sand he pulled a loaf of bread from his day pack. They broke the loaf in half and ate.

“Were you purring, then?” he said between swallows.

“Mm-hmm.”

“You had the trait inserted?”

She nodded, swallowed. “Last time I took the treatment.”

“The genes are from cats?”

“From tigers.”

“Ah.”

“It turns out to be a minor change in the larynx and vocal cords. You should try it, it feels really good.”

He was blinking and did not answer.

“Now who’s this friend you want me to take to Uranus?”

“Ann Clayborne.”

“Ah! Your old nemesis.”

“Something like that.”

“What makes you think she would go?”

“She might not. But she might. Michel says she’s trying some new things. And I think Miranda would be interesting to her. A moon knocked apart in an impact, and then reassembled, moon and impactor together. It’s an image I’d … like her to see. All that rock, you know. She’s fond of rock.”

“So I’ve heard.”

Russell and Clayborne, the green and the Red, two of the most famous antagonists in all the melodramatic saga of the first years of settlement. Those first years: a situation so claustrophobic Zo shuddered to think of it. Clearly the experience had brecciated the minds of all those who had suffered through it. And then Russell had had even more spectacular damage inflicted later on, as she recalled; hard to remember; all the First Hundred’s stories tended to blur together for her, the Great Storm, the lost colony, Maya’s betrayals — all the arguments, affairs, murders, rebellions, and so on — such sordid stuff, with scarcely a moment of joy in the whole thing, as far as she could tell. As if the old ones had been anaerobic bacteria, living in poison, slowly excreting the necessary conditions for the emergence of a fully oxygenated life.

Except perhaps for Ann Clayborne, who seemed, from the stories, to have understood that to feel joy in a rock world, you had to love rock. Zo liked that attitude, and so she said, “Sure, I’ll ask her. Or you should, shouldn’t you? You ask, and tell her I’m agreeable. We can make room in the diplomatic group.”

“It’s a Free Mars group?”

“Yes.”

“Hmm.”

He asked her questions about Jackie’s political ambitions, and she answered when she could, looking down her body and its curves, the hard muscles smoothed by the fat under the skin — hipbones flanking the belly, navel, wiry black pubic hair (she brushed bread crumbs out of it), long powerful thighs. Women’s bodies were much more handsomely proportioned than men’s, Michelangelo had been wrong about that, although his David made a best case for his argument, a flier’s body if ever there was one.

“I wish we could fly back up to the rim,” she said.

“I don’t know how to fly the birdsuits.”
