Twelve-year-old Sophie Mulvaney's world has been turned upside down. Mom lost her job at the TV station and broke up with Pratik, whom Sophie adored. Her teacher is making them do a special project about risk-taking, so Sophie gets roped into doing a triathlon. And to top it all off, she's started seeing bubbles above people's heads that tell her what these people are thinking. Seeing other people's thoughts seems like it should be cool, but it's actually just stressful.
