The girl stepped out and inched toward us, watching the ground carefully. She paused at a small twig, her dilated eyes goggling as if it were a boulder. She high-jumped far over it, and landed giggling. She wore an elaborate reindeer-skin jacket that hung past her knees, thickly embroidered with little beads of bone and wood. She also had tight fur trousers with lumpy beaded booties, sewn all in one piece like a child’s pajamas.
