Morisson Safford, Mori to her friends, has been having trouble sleeping. An insomniac since she was a teenager, she has never really worried about missing a few hours sleep, but now something is different. She has started seeing things. One of these visions particularly bothers her - a girl in the mirror. A girl with red eyes. It began with a fleeting glimpse of her in the corner of the eye. A trick of the light. A shadow. Now whenever Mori looks into that shining silver glass, another face stares back. She tried to laugh it off at first, thinking it was a hallucination left over from her lack of sleep, only now the strange girl is trying to make contact, pleading for Mori to help her. Soon, Mori is pulled into a terrifying world where she must fight to survive horrors she could never have imagined as she searches for a way back home.
