reincarnation good for all the passengers and crew of the Field Circus.
She isn't sure quite where the money is coming from. Presumably it's some creaky financial engine designed by Dad, stirring from its bear-market bunker for the first time in decades to suck dusty syndication feeds and liquidate long-term assets held against her return. She's duly grateful – even fervently so – for the details of her own impecunious position grow more depressing the more she learns about them. Her sole asset is the Field Circus, a thirty-years-obsolete starwhisp massing less than twenty kilograms including what's left of its tattered sail, along with its cargo of uploaded passengers and crew. Without the farsighted trust fund that has suddenly chugged into life, she'd be stranded in the realm of ever-circling leptons. But now the fund has sent her its offer of incarnation, she's got a dilemma. Because one of the Field Circus's passengers has never actually had a meatspace body…
Amber finds the Slug browsing quietly in a transparent space filled with lazily waving branches that resemble violet coral fans. They're a ghost-memory of alien life, an order of thermophilic quasi fungi with hyphae ridged in actin/myosin analogues, muscular and slippery filter feeders that eat airborne unicellular organisms. The Slug itself is about two meters long and has a lacy white exoskeleton of curves and arcs that don't repeat, disturbingly similar to a Penrose tiling. Chocolate brown organs pulse slowly under the skeleton. The ground underfoot is dry but feels swampy.
Actually, the Slug is a surgical disguise. Both it and the quasi-fungal ecosystem have been extinct for millions of years, existing only as cheap stage props in an interstellar medicine show run by rogue financial instruments. The Slug itself is one such self-aware scam, probably a pyramid scheme or even an entire compressed junk bond market in heavy recession, trying to hide from its creditors by masquerading as a life-form. But there's a problem with incarnating itself down in Sirhan's habitat – the ecosystem it evolved for is a cool Venusiform, thirty atmospheres of saturated steam baked under a sky the color of hot lead streaked with yellow sulphuric acid clouds.
The ground is mushy because it's melting, not because it's damp.
'You're going to have to pick another somatotype,' Amber explains, laboriously rolling her interface around the red-hot coral reef like a giant soap bubble. The environmental interface is transparent and infinitely thin, a discontinuity in the physics model of the simulation space, mapping signals between the human-friendly environment on one side and the crushing, roasting hell on the other. 'This one is simply not compatible with any of the supported environments where we're going.'
'I am not understanding. Surely I can integrate with the available worlds of our destination?'
'Uh, things don't work that way outside cyberspace.' Suddenly Amber is at a bit of a loss. 'The physics model could be supported, but the energy input to do so would be prohibitive, and you would not be able to interact as easily with other physics models as we can now.' She forks a ghost, demonstrates a transient other-Amber in a refrigerated tank rolling across the Slug's backyard, crushing coral and hissing and clanking noisily. 'You'd be like this.'
'Your reality is badly constructed, then,' the Slug points out.
'It's not constructed at all, it just evolved, randomly.' Amber shrugs. 'We can't exercise the same level of control over the underlying embedded context that we can over this one. I can't simply magic you an interface that will let you bathe in steam at three hundred degrees.'
'Why not?' asks the Slug. Translation wetware adds a nasty, sharp rising whine to the question, turning it into a demand.
'It's a privilege violation,' Amber tries to explain. 'The reality we're about to enter is, uh, provably consistent. It has to be, because it's consistent and stable, and if we could create new local domains with different rules, they might propagate uncontrollably. It's not a good idea, believe me. Do you want to come with us or not?'
'I have no alternative,' the Slug says, slightly sulkily. 'But do you have a body I can use?'
'I think -' Amber stops, suddenly. She snaps her fingers. 'Hey, cat!'
A Cheshire grin ripples into view, masked into the domain wall between the two embedded realities. 'Hey, human.'
'Whoa!' Amber takes a backward step from the apparition. 'Our friend here's got a problem, no suitable downloadable body. Us meat puppets are all too closely tied to our neural ultrastructure, but you've got a shitload of programmable gate arrays. Can we borrow some?'
'You can do better than that.' Aineko yawns, gathering substance by the moment. The Slug is rearing up and backing away like an alarmed sausage: Whatever it perceives in the membrane seems to frighten it. 'I've been designing myself a new body. I figured it was time to change my style for a while. Your corporate scam artist here can borrow my old template until something better comes up. How's that?'
'Did you hear that?' Amber asks the Slug. 'Aineko is kindly offering to donate her body to you. Will that do?' Without waiting, she winks at her cat and taps her heels together, fading out with a whisper and a smile: 'See you on the other side…'

It takes several minutes for the Field Circus's antique transceiver to download the dozens of avabits occupied by the frozen state vectors of each of the people running in its simulation engines. Tucked away with most of them is a resource bundle consisting of their entire sequenced genome, a bunch of phenotypic and proteome hint markers, and a wish list of upgrades. Between the gene maps and the hints, there's enough data to extrapolate a meat machine. So the festival city's body shop goes to work turning out hacked stem cells and fabbing up incubators.
It doesn't take very long to reincarnate a starshipful of relativity-lagged humans these days. First, City carves out skeletons for them (politely ignoring a crudely phrased request to cease and desist from Pamela, on the grounds that she has no power of attorney), then squirts osteoclasts into the spongy ersatz bone. They look like ordinary human stem cells at a distance, but instead of nuclei they have primitive pinpricks of computronium, blobs of smart matter so small they're as dumb as an ancient Pentium, reading a control tape that is nevertheless better structured than anything Mother Nature evolved. These heavily optimized fake stem cells – biological robots in all but name
– spawn like cancer, ejecting short-lived anucleated secondary cells. Then City infuses each mess of quasi- cancerous tissue with a metric shitload of carrier capsids, which deliver the
(This whole process is tediously slow and laughably obsolescent technology by the standards of the fast- moving core. Down there, they'd just set up a wake shield in orbit, chill it down to a fractional Kelvin, whack two coherent matter beams together, teleport some state information into place, and yank the suddenly materialized meatbody in through an airlock before it has time to asphyxiate. But then again, down in the hot space, they don't have much room for flesh anymore…)
Sirhan doesn't pay much attention to the pseudocancers fermenting and churning in the row of tanks that lines the Gallery of the Human Body in the Bush wing of the museum. Newly formed, slowly unskeletonizing corpses – like a time-lapse process of decay with a finger angrily twisting the dial into high-speed reverse – is both distasteful and aesthetically displeasing to watch. Nor do the bodies tell him anything about their occupants.
This sort of stuff is just a necessary prequel to the main event, a formal reception and banquet to which he has devoted the full-time attention of four ghosts.
He could, given a few less inhibitions, go Dumpster-diving in their mental archives, but that's one of the big taboos of the post-wetware age. (Spy agencies went meme-profiling and memory-mining in the third and fourth decades, gained a thought police rap sheet, and spawned a backlash of deviant mental architectures resilient to infowar intrusions. Now the nations that those spook institutions served no longer exist, their very landmasses being part of the orbiting noosphere construction project that will ultimately turn the mass of the entire solar system into a gigantic Matrioshka brain. And Sirhan is left with an uneasy loyalty to the one great new taboo to be invented since the end of the twentieth century – freedom of thought.)
So, to indulge his curiosity, he spends most of his waking fleshbody hours with Pamela, asking her questions
