"Can you believe this?" Maria whispered, her voice a tremor in the library. The announcement, plastered on the student union doors, had been the talk of the day.

She closed the book with a snap, the sound echoing in the silent library. She felt a dull ache behind her eyes, the beginning of a headache she knew would last for days. She needed to escape, to run far away from this place that was so suddenly and cruelly changing.
