«Quite something, isn't it?» I said as the habitat expanded to fill the screen.

Jocelyn grunted noncommittally, and shifted round under her bunk's webbing. We hadn't exchanged a hundred words in the last twenty-four hours. Not good. I had hoped the actual sight of the habitat might have lightened the atmosphere a little, raised a spark of interest. Twenty years ago, when we got married, she would have treated this appointment with boundless excitement and enthusiasm. That was a big part of her attraction, a delighted curiosity with the world and all it offered. A lot can happen in twenty years, most of it so gradual you don't notice until it's too late.

I sometimes wonder what traits and foibles I've lost, what attitude I've woven into my own personality. I like to think I'm the same man, wiser but still good-humoured. Who doesn't?

Eden had a long silver-white counter-rotating docking spindle protruding out from the hub of its northern endcap. Ithilien was too large to dock directly; the ship was basically a grid structure, resembling the Eiffel Tower, wrapped round the long cone of the fusion drive, with tanks and cargo-pods clinging to the structure as if they were silver barnacles. The life-support capsule was a sixty-metre globe at the prow, sprouting thermal radiator panels like the wings of some robotic dragonfly. In front of that, resting on a custom-built cradle, was the seed for another habitat, Ararat, Jupiter's third; a solid teardrop of biotechnology one hundred metres long, swathed in thermal/particle impact protection foam. Its mass was the reason Ithilien was manoeuvring so sluggishly.

Captain Saldana positioned us two kilometres out from the spindle tip, and locked the ship's attitude. A squadron of commuter shuttles and cargo tug craft swarmed over the gulf towards the Ithilien . I began pulling our flight bags from the storage lockers; after a minute Jocelyn stirred herself and started helping me.

«It won't be so bad,» I said. «These are good people.»

Her lips tightened grimly. «They're ungodly people. We should never have come.»

«Well, we're here now, let's try and make the most of it, OK? It's only for five years. And you shouldn't prejudge like that.»

«The word of the Pope is good enough for me.»

Implying it was me at fault, as always. I opened my mouth to reply. But thankfully the twins swam into the cabin, chattering away about the approach phase. As always the façade clicked into place. Nothing wrong. No argument. Mum and Dad are quite happy.

Christ, why do we bother?

The tubular corridor which ran down the centre of Eden's docking spindle ended in a large chamber just past the rotating pressure seal. It was a large bubble inside the polyp with six mechanical airlock hatches spaced equidistantly around the equator. A screen above one was signalling for Ithilien arrivals; and we all glided through it obediently. The tunnel beyond sloped down at quite a steep angle. I floated along it for nearly thirty metres before centrifugal force began to take hold. About a fifteenth of a gee, just enough to allow me a kind of skating walk.

An immigration desk waited for us at the far end. Two Eden police officers in smart green uniforms stood behind it. And I do mean smart: spotless, pressed, fitting perfectly. I held in a smile as the first took my passport and scanned it with her palm-sized PNC wafer. She stiffened slightly, and summoned up a blankly courteous smile. «Chief Parfitt, welcome to Eden, sir.»

«Thank you,» I glanced at her name disk, «Officer Nyberg.»

Jocelyn glared at her, which caused a small frown. That would be all round the division in an hour. The new boss's wife is a pain. Great start.

A funicular railway car was waiting for us once we'd passed the immigration desk. The twins rushed in impatiently. And, finally, I got to see Eden's interior. We sank down below the platform and into a white glare. Nicolette's face hosted a beautiful, incredulous smile as she pressed herself against the glass. For a moment I remembered how her mother had looked, back in the days when she used to smile—I must stop these comparisons.

«Dad, it's supreme,» she said.

I put my arm around her and Nathaniel, savouring the moment. Believe me, sharing anything with your teenage children is a rare event. «Yes. Quite something.» The twins were fifteen, and they hadn't been too keen on coming to Eden either. Nathaniel didn't want to leave his school back in the Delph company's London arcology. Nicolette had a boy she was under the impression she was destined to marry. But just for that instant the habitat overwhelmed them. Me too.

The cyclorama was tropical parkland, lush emerald grass crinkled with random patches of trees. Silver streams meandered along shallow dales, all of them leading down to the massive circumfluous lake which ringed the base of the southern endcap. Every plant appeared to be in flower. Birds flashed through the air, tiny darts of primary colour.

A town was spread out around the rim of the northern endcap, mostly single-storey houses of metal and plastic moated by elaborately manicured gardens; a few larger civic buildings were dotted among them. I could see plenty of open-top jeeps driving around, and hundreds of bicycles.

The way the landscape rose up like two green tidal waves heading for imminent collision was incredibly disorientating. Unnerving too. Fortunately the axial light-tube blocked the apex, a captured sunbeam threaded between the endcap hubs. Lord knows what seeing people walking around directly above me would have done to my already reeling sense of balance. I was still desperately trying to work out a viable visual reference frame.

Gravity was eighty per cent standard when we reached the foot of the endcap, the funicular car sliding down into a plaza. A welcoming committee was waiting for us on the platform; three people and five servitor chimps.

Michael Zimmels, the man I was replacing, stepped forward and shook my hand. «Glad to meet you, Harvey. I've scheduled a two-hour briefing to bring you up to date. Sorry to rush you, but I'm leaving on the Ithilien as soon as it's been loaded with He3 . The tug crews here, they don't waste time.» He turned to Jocelyn and the twins. «Mrs Parfitt, hope you don't mind me stealing your husband away like this, but I've arranged for Officer Coogan to show you to your quarters. It's a nice little house. Sally Ann should have finished packing our stuff by now, so you can move in straight away. She'll show you where everything is and how it works.» He beckoned one of the officers standing behind him.

Officer Coogan was in his late twenties, wearing another of those immaculate green uniforms. «Mrs Parfitt, if you'd like to give your flight bags to the chimps, they'll carry them for you.»

Nicolette and Nathaniel were giggling as they handed their flight bags over. The servitor chimps were obviously genetically adapted; they stood nearly one metre fifty, without any of the rubber sack paunchiness of the pure genotype primates cowering in what was left of Earth's rain forests. And the quiet, attentive way they stood waiting made it seem almost as though they had achieved sentience.

Jocelyn clutched her flight bag closer to her as one of the chimps extended an arm. Coogan gave her a slightly condescending smile. «It's quite all right, Mrs Parfitt, they're completely under control.»

«Come on, Mum,» Nathaniel said. «They look dead cute.» He was stroking the one which had taken his flight bag, even though it never showed the slightest awareness of his touch.

«I'll carry my own bag, thank you,» Jocelyn said.

Coogan gathered himself, obviously ready to launch into a reassurance speech, then decided chiding his new boss's wife the minute she arrived wasn't good policy. «Of course. Er, the house is this way.» He started off across the plaza, the twins plying him with questions. After a moment Jocelyn followed.
