Something is haunting Mardy Watt. It's been in her room, it's fooling her friends and it's upsetting her home life. And the trouble is, nobody realises what is happening except Mardy herself. Exactly what it is and why it is picking on her, Mardy doesn't know - but she does know that she has to find out, before it takes over and replaces her completely.
