Sarah is used to the stares and the whispers. And she’s definitely used to the questions about the big purple birthmark on her cheek. So, when three magical Moon Blobs appear and offer her the power to turn invisible whenever she wants, she jumps at the chance for one day without stares or whispers. But being invisible means her best friend can’t find her at recess, her teacher doesn’t see her raised hand, and when she paints something beautiful, nobody can see the girl who made it. The loneliness of being unseen hurts worse than any stare ever did. Sarah discovers that being noticed for who she really is, birthmark and all, is better than disappearing completely.
