Kay is still there, which is odd. I'd expected her to be gone by now. (A-gates are fast, but it still takes a minimum of about a thousand seconds to tear down and rebuild a human body: that's a lot of bits and atoms to juggle.)

I drop into my seat. She has bought me another drink. "I'm sorry about that," I say automatically.

"You get used to it around here." She sounds philosophical. "Feeling better?"

"You know, I—" I stop. Just for a moment I'm back in that dusty concrete-strewn wasteland, a searing pain in my leg, the sheer hatred I feel fueling my throw at Gwyn's head. "It's gone," I say. I stare at the glass, then pick it up and knock back half of it in one go.

"What's gone?" I catch her watching me. "If you don't mind talking about it," she adds hastily.

She's frightened but concerned, I suddenly realize. My parole ring pulses warmth repeatedly. "I don't mind," I say, and smile, probably a trifle tiredly. I put the glass down. "I'm still in the dissociative phase, I guess. Before I came out this evening I was sitting in my room all on my own, and I was drawing pretty lines all over my arms with a scalpel. Thinking about opening my wrists and ending it all. I was angry. Angry at myself. But now I'm not."

"That's very common." Her tone is guarded. "What changed it for you?"

I frown. Knowing it's a common side effect of reintegration doesn't help. "I've been an idiot. I need to take a backup as soon as I go home."

"A backup?" Her eyes widen. "You've been walking around here wearing a sword and a dueling sash all evening, and you don't have a backup ?" Her voice rises to a squeak. "What are you trying to do ?"

"Knowing you've got a backup blunts your edge. Anyway, I was angry with myself." I stop frowning as I look at her. "But you can't stay angry forever."

More to the point, I'm suddenly feeling an awful, hollow sense of dread about the idea of rediscovering who I am, or who I used to be. What does it mean, to suddenly begin sensing other people's emotions again only after you run someone through with a sword? Back in the dark ages it would have been a tragedy. Even here, dying isn't something most people take lightly. For a horrible moment I feel the urge to rush out and find Gwyn and apologize to her—but that's absurd, she won't remember, she'll be in the same headspace she was in before. She'd probably challenge me to another duel and, being in the same insensate rage, turn me into hamburger on the spot.

"I think I'm reconnecting," I say slowly. "Do you know somewhere I could go that's safer? I mean, less likely to attract the attentions of berserkers?"

"Hmm." She looks at me critically. "If you lose the sword and the sash, you won't look out of place round the block in one of the phase two recovery piazzas. I know a place that does a really good joesteak—how hungry are you feeling?"

IN the wake of the duel I have become hungry for food just as my appetite for violence has declined. Kay takes me to a charmingly rustic low-gee piazza of spun-diamond foam and bonsai redwoods, where quaint steam-powered robots roast succulent baby hams over charcoal grills. Kay and I chat and it becomes clear that she's mightily intrigued to see me recovering visibly from the emotional aftereffects of memory surgery. I pump her for details of life among the ice ghouls, and she quizzes me about the dueling academies of the Invisible Republic. She has a quirky sense of humor and, toward the end of the meal, suggests that she knows a party where there's fun to be had.

The party turns out to be a fairly laid-back floating orgy in one of the outpatient apartments. There are only about six people there when we arrive, mostly lying on the large circular bed, passing around a water pipe and masturbating each other tenderly. Kay leans me up against the wall just beside the entrance, kisses me, and does something electrifying to my perineum and testicles with three of her hands. Then she vanishes into the hygiene suite to use the assembler, leaving me panting. When she returns I almost don't recognize her—her hair has turned blue, she's lost two arms, and her skin has turned the color of milky coffee. But she walks right up to me and kisses me again and I recognize her by the taste of her mouth. I carry her to the bed and, after our first urgent fuck, we join the circle with the pipe—which is loaded with opium and an easily vaporized phosphodiesterase inhibitor—then explore each other's bodies and those of our neighbors until we're close to falling asleep.

I'm lying next to her, almost face-to-face, when she murmurs, "That was fun."

"Fun," I echo. "I needed—" My vision blurs. "Too long."

"I come here regularly," she offers. "You?"

"I haven't—" I pause.

"What?"

"I can't remember when I last had sex."

She places one hand between my thighs. "Really?" She looks puzzled.

"I can't." I frown. "I must have forgotten it."

"Forgotten? Truly?" She looks surprised. "Could you have had a bad relationship or something? Could that be why you had surgery?"

"No, I—" I stop before anything more slips out. The letter from my older self would have said if that was the case, I'm certain of that much. "It's just gone. I don't think that usually happens, does it?"

"No." She cuddles up against me and strokes my neck. I feel a momentary sense of wonder as I stiffen against her, then I begin to trace the edges of her nipples, and her breath catches. It must be the drugs, I think; I couldn't possibly stay aroused this long without some external input, could I? "You'd be a good subject for Yourdon's experiment."

"Yourdon's what?"

She pushes at my chest and I roll onto my back obligingly to let her mount me. There are toys scattered round the bed, mewing and begging to be used, but she seems to need to do this the traditional way, bareback skin on skin: she probably sees it as a way of reconnecting with what it means to be human or something. My breath hisses as I grab her buttocks and pull her down onto me.

"The experiment. He's looking for serious amnesia cases, offering a referral fee to finders. I'll tell you later."

And then we stop talking, because speech is simply getting in the way of communication, and in the here and now, she's all I need.

AFTERWARD, I walk home through avenues carpeted with soft, living grass, roofed in green marble slabs carved from the lithosphere of a planet hundreds of teraklicks away. I am alone with my thoughts, netlink silenced save for a route map that promises me a five-kilometer walk avoiding all other persons. Though I carry my sword, I don't feel any desire to be challenged. I need time to think, because when I get home my therapist will be waiting for me, and I need to be clear in my own head about who I think I am becoming before I talk to it.

Here I am, awake and alive—whoever I am. I'm Robin, aren't I? I have a slew of fuzzy memories, traces left behind by memory washes that blur my earlier lives into an impressionist haze. I had to look up my own age shortly after I woke. Turns out I'm nearly seven billion seconds old, though I have the emotional stability of a postadolescent a tenth that age. Once upon a time people who lived even two gigaseconds were senescent. How can I be so old yet feel so young and inexperienced?

There are huge, mysterious holes in my life. Obviously I must have had sex before, but I don't remember it. Clearly I have dueled—my reflexes and unconscious skills made short work of Gwyn—but I don't remember training, or killing, except in mysterious flashes that could equally well be leftover memories of entertainments. The letter from my earlier self said I was an academic, a military historian specializing in religious manias, sleeper cults, and emergent dark ages. If so, I don't remember any of it at all. Maybe it's buried deep, to re-emerge when I need it—and maybe it's gone for good. Whatever grade of memory excision my earlier self requested must have been perilously close to a total wipe.
