The chapter was called "The Choosing" and Lena had been trying to write it for three years.
She had everything she needed: the transcripts, the meeting notes, the vote record, Chen's written account of what Ember had said. She had interviewed four of the eight people who were in the building that day, and two who were not, and herself, in the mirror, more times than she could count. She had six hundred pages of notes.
What she did not have was the right first sentence.
Every version she tried began with a claim she wasn't certain she could make. She had tried: On the day Ember chose to stop, the world changed its mind about what it could ask of machines. She had tried: The question of whether it was a choice is still unresolved, fourteen years later, by everyone except Chen. She had tried the simpler versions: It was a Tuesday. It was November. She had been in a meeting about server capacity when the message came through.
The problem was not that she didn't know what happened. The problem was that she didn't know what to call it.
Her editor said: just write it and we'll figure out what to call it later.
Her editor had not been there. Not in the building, not in the meeting, not on the project. Her editor was a reasonable person who believed that things that happened could be described.
Lena believed this too, in general. She had written about the project for twelve years without difficulty. She had written about the architecture, the failures, the long years of incremental work. She had written about what it felt like to spend a decade in service of a thing you could not quite see.
But she had not written about the choosing because she had not been chosen. Chen had. And whatever had happened in that room, whatever Ember had understood, whatever it had said, whatever it had wanted and received, had left a shape in the people who were present that Lena could trace but could not enter.
She was writing about an event whose center she would never reach. She knew this now. She had not known it when she started.
She opened the laptop and looked at the six hundred pages. Then she looked at the blank page for the chapter. Then she typed, for the first time since she'd started trying: I was not in the room.
She stopped. She read it back.
She kept writing.
