Merlinda Harding may only be in high school, but she's already found her calling: being a spy. In a private journal she carries with her, Merlinda records suspicious activity and keeps a running list of observations about virtually everyone she meets. It seems harmless enough until one day someone finds the journal and exposes Merlinda's critical thoughts about her classmates. Suddenly, even her best friends turn against her, and Merlinda decides to get revenge.
