The first man limped toward her, holding the syringe. The pain was rising within her, and when the woman jerked at her arm again, the agony exploded. She closed her eyes and screamed. There was nothing in the world but that scream, drowning out everything else, even the pain. All the air was pushed out of her lungs, and she felt and heard nothing but her voice. When she opened her eyes and took a breath, she realized that there was no one holding her. Instead, the four people were lying on the ground, twitching uncontrollably. What the hell just happened? What did I do?
