Dear Fox, Hey. It\u2019s Sahra. I\u2019m tagging you from center M691, Black Hawk, South Dakota. It\u2019s night and the lights are on in the center. It\u2019s run by an old white guy with a hanging lip\u2014he\u2019s talking to my mom at the counter. Mom\u2019s okay. We\u2019ve barely mentioned you since we left the old group in the valley, just a few weeks after you disappeared. She said your name once, when I found one of your old slates covered with equations. \u201cWell,\u201d she said. \u201cThat was Fox.\u201d | Copyright 2016 by Sofia Samatar.
