When the world is threatened by an unknown threat - hordes of huge bugs that can destroy all the electronics on the planet - the worst thing that could happen to Piper is the loss of her talent for flight. In fact, this is generally the worst thing that could happen to her, because who is she now that she can no longer soar in the skies? And then it only gets worse: her best friend Conrad and the rest of the guys with extraordinary powers begin to shun Piper, because now she is different. However, when the children get into trouble and Piper turns out to be the only hope for their team, and indeed for the whole world, the girl has to learn the most important thing about herself: is she worth anything without her flights?
