Pita sat on a padded chair, gripping its cushioned arms. She could smell the plastic hood that was wrapped tightly around her head and face, and the lingering perfume of one of the people who had come in to the room earlier. And she could feel the warm stream of air from a heat vent overhead. But otherwise, her senses were completely blocked. The hood covered her eyes, and soft pads over her ears delivered a steady white-noise hiss. The sound made it impossible to think, let alone hear anything.
