From the introduction:
Michael screamed until he was hoarse and then continued screaming for what seemed like eternity. Finally, he pushed the pain down until it felt merely like a burning spike being pounded in his head. Ending his own screaming allowed him to hear the screaming all around him. He opened his eyes and sat up to see bodies writhing on the ground in every direction.
Michael heard a shout and turned to see a girl running towards him.
"Here's one over here!" She yelled behind her, motioning towards Michael.
He waited until she arrived and asked the question burning in his head almost as hotly as the spike. "Where the hell am I?"
