The problem is not everyone likes Pippa asking questions and snooping around. The people involved are not saints - some sell drugs and have assaulted people. One may even have had a relationship with teenager. The closer Pippa gets to the truth and the more she pushes people, the more danger she risks for herself and family.
Pippa shares her findings (most of them, anyway) on a podcast which grows in popularity. The podcast adds to the tension as everyone knows who possible suspects are and learn of their questionable actions.
I have read several teen suspense books recently - this is the best one so far. Pippa is a driven young woman who hesitates but never turns away from finding the truth. Her drive moves the story forward at a quick pace. Danger lurks in so many places with the reader never really knowing what the consequences will be. This is edge of your seat stuff.
