Children were vehicles for passing things along. These things could be kingdoms, rich wedding gifts, stories, grudges, blood feuds. Through children, alliances were forged; through children, wrongs were avenged. To have a child was to set loose a force in the world.

If you want what's in the package you should at least know how to get the string off, is what I say.

No more photos. Surely there are enough. No more shadows of myself thrown by light onto pieces of paper, onto squares of plastic. No more of my eyes, mouths, noses, moods, bad angles. No more yawns, teeth, wrinkles. I suffer from my own multiplicity. Two or three images would have been enough, or four, or five. That would have allowed for a firm idea: This is she. As it is, I'm watery, I ripple, from moment to moment I dissolve into my other selves. Turn the page: you, looking, are newly confused. You know me too well to know me. Or not too well: too much.

Plague has hung over human history. The biggest human extinction was after 1492 in North and South America when the mortality rate was 95 per cent, which is enormous. But again, I'm actually giving you grounds for optimism: There were enough to continue. The five per cent who made it through are what you need to survive a bottleneck, which we have been through before.

Speculative fiction encompasses that which we could actually do. Sci-fi is that which we're probably not going to see.

I sink down into my body as into a swamp, fenland, where only I know the footing…. I’m a cloud, congealed around a central object, the shape of a pear, which is hard and more real than I am and glows red within its translucent wrapping. Inside it is a space, huge as the sky at night and dark and curved like that, though black-red rather than black.

By now you know: I come from another planet. But I will never say to you, "Take me to your leaders." Even I--unused to your ways though I am--would never make that mistake. We ourselves have such beings among us, made of cogs, pieces of paper, small disks of shiny metal, scraps of coloured cloth. I do not need to encounter more of them. Instead I will say, "Take me to your trees. Take me to your breakfasts, your sunsets, your bad dreams, your shoes, your nouns. Take me to your fingers; take me to your deaths." These are worth it. These are what I have come for.
