When popular schoolgirl Mary wakes up on her seventeenth birthday she is shocked to find herself naked with scratches down her back in a sofa warehouse in downtown Manhattan and a street full of people staring up at her. What on earth was she doing the night before? This isn't like the usual hangover. The day gets progressively weirder from there. At school, no one treats her like the popular girl she's always been. Her boyfriend drops her for no reason. Everyone is behaving strangely. Mary finds herself in a wildly confusing world that keeps getting stranger and scarier. Eventually, she inhabits the bodies of seven people who were close to her, and finds out just what each of them thought of her -- and it isn't pretty.
