“The death of Fire Station 10 affected me deeply. She had not been the smartest building, but she had been a friend for as long as I can remember. She was one story tall, the sole holdover from a much earlier time in the neighborhood—a piece of cinderblock nostalgia, of high-maintenance wood and plaster from an earlier age. Her brain and smart utilities were a retrofit, cobbled onto the cinderblock building later, in a clumsy addition on the back. When she was built, buildings had no minds.”

It’s the lollipops that break you. The thought of your child sucking on one during a lockdown drill carries enough cognitive dissonance that your brain has trouble actually comprehending it. You know the purpose—the methodology behind it all—lollipops in their mouths will keep preschoolers quiet, and surely the sugar can’t hurt. But the fact that your preschooler needs to know how to behave in case there’s an active shooter is so disturbing that you wish there was a way to retreat into your shell, like a defiant hermit crab.

First, I want to give you this moment. You will understand why in the end. We were walking on the trail, the way we did on Sundays: the sun-washed gully, the open air, the shadows of last night’s rain staining the earth dark and slick beneath our boots. At the river’s edge, I caught my husband’s hand and pointed at a stack of topaz-eyed turtles that had piled themselves ancient and precarious as a cairn. Here are the shapes and shades that colored my life, before. Then we looked up and saw you.

Noah Stubbs eyes the large white pill pinched between his thumb and forefinger, remembering the first time he hit golf balls on the moon with Gord. “I wonder,” Gord says to him as Noah lines up on the tee, “just how far these suckers’ll really go?” THWACK! Noah swings. The little ball hurtles into the Lunar day, a pinprick of speeding light bright against the velvet sky. Long after the ball becomes invisible to the naked eye, his suit’s visor tracks its trajectory until it drops towards the ground. They parked the hopper at the top of the Virgo Escarpment.

Two hundred ships moved through the stars, leaving an iridescent trail of transmission beacons in their wake. Five billion kilometers long, the beacons stretched all the way to Earth, a desiccated and shaken planet that the passengers once called home. Sometimes simple messages from the ships arrived in the data. After a long time, images came and—after an even longer time—clips of the passengers going about their lives. But the vast distances meant these clips were rare. Normally an image arriving on Earth was cause for celebration, because it meant the crew was still alive, or at least the ship’s systems were still functioning.
