Rosalyn managed a flimsy laugh but said nothing else. It wasn’t her friends that insisted on the combination birthday and Christmas, but her family. The only person that ever paid much attention to her birthday was her best friend and best workmate, Angela Kerwin, who insisted on taking her out each year. They shared a birthday, though Angela was several years older. And they shared an addiction to work, though they relaxed their strict schedules on that one day a year, when they celebrated their birthday together. The Faubourg Sky Tower with its rooftop bar. They would sip lemon drops and watch the ships departing Earth, flashing toward the stars in tiny red blinks. Angela always stopped her before the night spiraled out into dancing or karaoke.

“Thanks, Mom,” Rosalyn would tease, and then they would walk downtown to look at all the dazzling Christmas lights. Angela’s last message had arrived a month ago. “I’m going to keep sending these until you ping me back,” it said. “I know you’re angry, but at me, too? Come on, Rozzy, I miss you. I want to tell you about everything I’m doing out here. It’s wild. These samples . . . Your head would spin if you saw them. If we’re right, we’re going to change medicine forever. Okay, okay, I love you. Reach out.”

“Well,” Owen sighed. “Captain Murder Ship certainly isn’t going to win employee of the month anytime soon.” His vacuum whirred, then jammed, and he leaned down to pry a chunk of femur out of the hose. She couldn’t help but watch him do it, so casual, like picking a booger, flicking it away. Not that she would do any differently, but still, it made her freeze. “Can you believe it? He just snapped. Went completely mental and did in his entire crew . . . They found him in a titty bar on Tokyo Bliss Station. Said he had no idea who he was or what he had done. Yeah. I’ll fucking bet. Loser.”

“Nobody just snaps,” Rosalyn replied. She pretended to fuss with her vacuum, no longer so keen on doing the work. No, nobody snapped. There were always signs. A short temper here. A barked insult there. A strange, dark blankness in the eyes, colder than the black void of space. Shark eyes. Inhuman eyes. Blame and shame, but always soothed with an apology. Tearful I love yous after the rage.

“Dunno, he had a squeaky-clean record,” Owen continued. That didn’t matter either, Rosalyn knew. He lifted the barrel of the vacuum hose up to his curved, clear visor and looked down it with one eye closed. His was a face for smirking, and the smile lines carved around his mouth and wrinkling at his eyes aged him. Certainly the work aged him, too. Rosalyn had spied more than one gray hair in the mirror since starting with Merchantia.
