Twelve-year-old Sophie Mulvaney's world has been turned upside down after her mum loses her job and breaks up with Pratik, who Sophie adored. But then: Sophie starts seeing bubbles above people's heads that tell her what they are thinking. Seeing other people's thoughts should be cool, but it's actually just stressful - what does it mean that Pratik wishes she and mum were eating with him? What does Viv Carlson's school project have to do with her? And when she finds out through the thought bubbles that her best friend Kaya likes her other best friend, Rafael - the very same Rafael that Sophie has her own crush on - Sophie has to find a way to figure out how to deal with knowing more than she should.
