A power tool yelped its way through something, at a distance. She turned back, to check her face in the mirror, then stepped out, into a confusing space made more so by that light. Whatever the building’s top several floors had contained had been stripped to raw concrete, little else, with only a small portion of the uppermost floor remaining. Scaffolding ran up to this, supporting a temporary zigzag of aluminum stairs. Blue plastic tarps, semitranslucent, like the ones covering the cardboard shanties she’d passed in the street, were laced together, strung taut, across walls of glass.
