If you could have a superpower, which one would you choose? Super strength? Super speed? The ability to talk to animals? When nine-year-old Mitch Clarke is asked this by his Aunt Evie, he knows right away-invisible flying! But what he doesn't know is that he has actually just chosen a superpower that he will have for the next two years, and this has happened in his family for generations.With his newfound abilities, Mitch goes flying around his school and neighbourhood in Hamilton, Ontario. Soon discovering he can also shrink, he has fun using his power to explore the inside of Lego creations. However, Mitch quickly discovers that having powers means you find out about other people's secrets and problems-like the new kid in his class who is living in a shelter. With support from his Aunt Evie, Mitch vows to use his superpower for good, and in the process learns that helping others might be the most powerful ability of all.
