Or, alternatively, they died. The First Settlers’ Institute that Michel continued to work with had a smaller group of subjects every year. Even Vlad died, one year. After that Marina and Ursula moved from Acheron to Odessa. Nadia and Art had already moved to west Odessa, after their daughter Nikki had grown up and moved there. Even Sax Russell took an apartment in town, though he spent most of the year in Da Vinci still.

For Maya these moves were both good and bad. Good because she loved all these people, and it felt like they were clustering around her, which pleased her vanity. And it was a great pleasure to see their faces. So she helped Marina, for instance, to help Ursula to deal with Vlad’s loss. It seemed that Ursula and Vlad had been the true couple, in some sense— though Marina and Ursula . . . well, there were no terms for the three points of a ménage à trois, no matter how it was constituted. Anyway Marina and Ursula were now the remainder, a couple very close in their grieving, otherwise much like the young native same-sex couples one saw in Odessa, men arm in arm on the street (a comforting sight), women hand in hand.

So she was happy to see the two of them, or Nadia, or any of the rest of the old gang. But she couldn’t always remember the incidents they discussed as if unforgettable, and this was irritating. Another kind of jamais vu; her own life. No, it was better to focus on the moment, to go down and work on water, or the lighting for the current play, or sit chatting in the bars with new friends from work, or with complete strangers. Waiting for that enlightenment to someday come. . . .

Samantha died. Then Boris. Oh there were two or three years between their deaths, but still, after the long decades during which none of them had died, this frequency pattern felt very fast. So they got through those funerals as best they could, and meanwhile everything was getting darker, as on the corniche when a black squall approached from over the Hellespontus— Terran nations still sending up unauthorized people and landing them, the UN still threatening, China and Indonesia suddenly at each other’s throats, Red ecoteurs blowing things up more and more indiscriminately, recklessly, killing people. And then Michel came up the stairs, heavy with grief; “Yeli died.”

“What? No— oh no.”

“Some kind of heart arrhythmia.”

“Oh my God.”

Maya hadn’t seen Yeli for decades, but to lose another one of the remaining First Hundred— lose the possibility of ever seeing again Yeli’s shy smile . . . no. She didn’t hear the rest of what Michel said, not so much from grief as from distraction. Or grief for herself.

“This is going to happen more and more often, isn’t it?” she said at last, when she noticed Michel staring at her.

He sighed. “Maybe.”
