She set off, forcing herself along. The space pressed inward, the weight of the structure a physical presence, the scents of hot steel and antifreeze heavy in the dampness. Mars shimmered in her peripheral vision, the edge of panic following as she moved. She had no defenses against her past; the further the red planet receded, the more it remained alive in her mind. She’d tried to shed her memories, thought she had at times, but they returned again and again, waiting until she was asleep or tired and defenseless. Her heart kicked with an unsteady rhythm and sweat ran between her shoulder blades. She smelled herself, a thick animal scent that reeked of fear.
