Alex isn't a bad kid - at least, that's what he tells himself. A joke here, a mean comment there... until the day he meets Mikey, a mysterious cat who seems to know exactly what Alex has been doing. After Alex crosses a line, reality shifts and he begins waking up inside nine different students' lives at his school. He feels the fear of intimidation, the loneliness of exclusion, the humiliation of cyberbullying, and the damage of rumors - all without being able to speak. Alex can't escape until he understands the lesson Mikey is waiting to teach: you don't need nine lives to be a hero - you need the courage to change the one you have.
