standing over Freya. “What are you doing up?”
    “I saw the light.”
    “All right. Sorry. Come on in. Do you want anything to drink?”
    “No.”
    “Hot chocolate?”
    “Yes.” They don’t often have chocolate powder, it’s one of the rationed foods.
    Devi puts the teapot on to boil. The glow of the stove coil adds red light to the blue light from the screen.
    “What are you doing?” Freya asks.
    “Oh, nothing.” Devi’s mouth tightens at the corner. “I’m trying to learn quantum mechanics again. I knew it when I was young, or I thought I did. Now I’m not so sure.”
    “How come?”
    “Why am I trying?”
    “Yes.”
    “Well, the computer that runs the ship is partly a quantum computer, and no one in the ship understands quantum mechanics. Well, that’s not fair, I’m sure there are several in the math group who do. But they aren’t engineers, and when we get problems with the ship, there’s a gap between what we know in theory and what we can do. I just want to be able to understand Aram and Delwin and the others in the math group when they talk about this stuff.” She shakes her head. “It’s going to be hard. Hopefully it won’t really matter. But it makes me nervous.”
    “Shouldn’t you be sleeping?”
    “Shouldn’t you? Here, drink your hot chocolate. Don’t nag me.”
    “But you nag me.”
    “But I’m the mom.”
    They sip and slurp together in silence. Freya begins to feel sleepywith the heat in her stomach. She hopes the same will happen to Devi. But Devi sees her put her head on the table, and goes back to talking to the screen.
    “Why a quantum computer?” she asks plaintively. “A classical computer with a few zettaflops would have been enough to do anything you might need, it seems to me.”
    “In certain algorithms the ability to exploit superposition makes a quantum computer much faster,” the ship replies. “For factoring, some operations that would have taken a classical computer a hundred billion billion years will only take a quantum computer twenty minutes.”
    “But do we need to do that factoring?”
    “It helps aspects of navigation.”
    Devi sighs. “How did it get this way?”
    “How did what get what way?”
    “How did this happen?”
    “How did what happen?”
    “Do you have an account of how this voyage began?”
    “All the camera and audio recordings made during the trip have been kept and archived.”
    Devi hmphs. “You don’t have a summary account? An abstract?”
    “No.”
    “Not even the kind of thing one of your quantum chips would have?”
    “No. All the chip data are kept.”
    Devi sighs. “Keep a narrative account of the trip. Make a narrative account of the trip that includes all the important particulars.”
    “Starting from now?”
    “Starting from the beginning.”
    “How would one do that?”
    “I don’t know. Take your goddamn superposition and collapse it!”
    “Meaning?”
    “Meaning summarize, I guess. Or focus on some exemplary figure. Whatever.”
    Silence in the kitchen. Humming of screens, whoosh of vents. As Freya gives up and goes back to bed, Devi continues talking with the ship.

    Sometimes feeling Devi’s fear gets so heavy in Freya that she goes out into their apartment’s courtyard alone, which is allowed, and then out into the park at the back edge of the Fetch, which is not. One evening she walks to the corniche to watch the afternoon onshore wind tear at the lake surface, the boats out there scudding around tilted at all angles, the boats tied to the dock or moored near it bobbing up and down, the white swans rocking under the wall of the corniche, hoping for bread crumbs. Everything gleams in the late afternoon light. When the sunline flares out at the western wall, leaving the hour of twilight glow, she heads back fast for home, intent to get back in the courtyard before Badim calls her up for dinner.
    But three faces appear under a mulberry tree in the little forest park behind the corniche,
