Kromer the big ape and Gilmartin pulled me outside into the sunlight and it was like a knife in my eyes. I couldn’t believe how bright it was. They tossed me down in the street and when I got up Kromer punched me, hard.

Then Gloria came outside. I don’t know how she found out, if she heard me screaming or if Ed woke her. Anyway she gave Kromer a pretty good punch in the side and said, “Leave him alone!”

Kromer was surprised and he moaned and I got away from him. Gloria punched him again. Then she turned around and gave Gilmartin a kick in the nuts and he went down. I’ll always remember in spite of what happened next that she gave those guys a couple they’d be feeling for a day or two.

The gang who beat the crap out of us were a mix of the militia and some other guys from the town, including Lane’s boyfriend. Pretty funny that he’d take out his frustration on us, but that just shows you how good Fearing had that whole town wrapped around his finger.

Outside of town we found an old house that we could hide in and get some sleep. I slept longer than Gloria. When I woke up she was on the front steps rubbing a spoon back and forth on the pavement to make a sharp point, even though I could see it hurt her arm to do it.

“Well, we did get fed for a couple of days,” I said.

Gloria didn’t say anything.

“Let’s go up to San Francisco,” I said. “There’s a lot of lonely women there.”

I was making a joke of course.

Gloria looked at me. “What’s that supposed to mean?”

“Just that maybe I can get us in for once.”

Gloria didn’t laugh, but I knew she would later.

Greg Egan

Yeyuka

Though not all of his stories are about information technology, and most make only passing nods, if any, to the icons of classic CP, most Greg Egan stories are like’ 80s CP in their foregrounding of ideas over character. A typical Egan story bombards the reader with ideas and their implications and lets literary concerns go hang. This one has a nifty technological device at its heart. But it turns into a story about first-vs.-third world economics, and then, uncharacteristically, into a story about one person’s moral decision.

Neuromancer, through its transnational megacorporations and the brutal struggle of its protagonists in a street-level no-holds-barred marketplace, offers an implicit critique of capitalism. Here the critique of corporate power bound only by profit margins is overt.

On my last day in Sydney, as a kind of farewell, I spent the morning on Bondi Beach. I swam for an hour, then lay on the sand and stared at the sky. I dozed off for a while, and when I woke there were half a dozen booths set up amid the sun bathers, dispensing the latest fashion: solar tattoos. On a touch-screen the size of a full-length mirror, you could choose a design and then customise it, or create one from scratch with software assistance. Computer-controlled jets sprayed the undeveloped pigments onto your skin, then an hour of uv exposure rendered all the colours visible.

As the morning wore on, I saw giant yellow butterflies perched between shoulder blades, torsos wrapped in green-and-violet dragons, whole bodies wreathed in chains of red hibiscus. Watching these images materialise around me, I couldn’t help thinking of them as banners of victory. Throughout my childhood, there’d been nothing more terrifying than the threat of melanoma — and by the turn of the millennium, nothing more hip than neck-to-knee lycra. Twenty years later, these elaborate decorations were designed to encourage, to boast of, irradiation. To proclaim, not that the sun itself had been tamed, but that our bodies had. To declare that cancer had been defeated.

I touched the ring on my left index finger, and felt a reassuring pulse through the metal. Blood flowed constantly around the hollow core of the device, diverted from a vein in my finger. The ring’s inner surface was covered with billions of tiny sensors, spring-loaded, funnel-shaped structures like microscopic Venus fly-traps, each just a few hundred atoms wide. Every sizable molecule in my bloodstream that collided with one of these traps was seized and shrink-wrapped, long enough and tightly enough to determine its shape and its chemical identity before it was released.

So the ring knew exactly what was in my blood. It also knew what belonged, and what didn’t. Under its relentless scrutiny, the biochemical signature of a viral or bacterial infection, or even a microscopic tumour far downstream, could never escape detection for long — and once a diagnosis was made, treatment was almost instantaneous. Planted alongside the sensors were programmable catalysts, versatile molecules that could be reshaped under computer control. The ring could manufacture a wide range of drugs from raw materials circulating in the blood, just by choosing the right sequence of shapes for these catalysts — trapping the necessary ingredients together in nooks and crannies moulded to fit like plaster casts around their combined outlines.

With medication delivered within minutes or seconds, infections were wiped out before they could take hold, tiny clusters of cancer cells destroyed before they could grow or spread. Linked by satellite to a vast array of medical databases, and as much additional computing power as it required, the ring gave me a kind of electronic immune system, fast enough and smart enough to overcome any adversary.

Not everyone on the beach that morning would have had their own personal HealthGuard, but a weekly session on a shared family unit, or even a monthly check-up at their local GP, would have been enough to reduce their risk of cancer dramatically. And though melanoma was the least of my worries — fair-skinned, I was covered in sunscreen as usual; fatal or not, getting burnt was painful — with the ring standing guard against ten thousand other possibilities, I’d come to think of it as a vital part of my body. The day I’d installed it, my life expectancy had risen by fifteen years — and no doubt my bank’s risk-assessment software had assumed a similar extension to my working life, since I’d be paying off the loan I’d needed to buy the thing well into my sixties.

I tugged gently at the plain metal band, until I felt a sharp warning from the needle-thin tubes that ran deep into the flesh. This model wasn’t designed to be slipped on and off in an instant like the shared units, but it would only take a five-minute surgical procedure under local anaesthetic to remove it. In Uganda, a single HealthGuard machine served 40 million people — or rather, the lucky few who could get access to it. Flying in wearing my own personal version seemed almost as crass as arriving with a giant solar tattoo. Where I was headed, cancer had very definitely not been defeated.

Then again, nor had malaria, typhoid, yellow fever, schistosomiasis. I could have the ring immunise me against all of these and more, before removing it … but the malaria parasite was notoriously variable, so constant surveillance would provide far more reliable protection. I’d be no use to anyone lying in a hospital bed for half my stay. Besides, the average villager or shanty-town dweller probably wouldn’t even recognise the thing, let alone resent it. I was being hypersensitive.

I gathered up my things and headed for the cycle rack. Looking back across the sand, I felt the kind of stab of regret that came upon waking from a dream of impossible good fortune and serenity, and for a moment I wanted nothing more than to close my eyes and rejoin it.

Lisa saw me off at the airport.

I said, “It’s only three months. It’ll fly past.” I was reassuring myself, not her.

“It’s not too late to change your mind.” She smiled calmly; no pressure, it was entirely my decision. In her eyes, I was clearly suffering from some kind of disease — a very late surge of adolescent idealism, or a very early midlife crisis — but she’d adopted a scrupulously nonjudgmental bedside manner. It drove me mad.
