More than anything, Mel wants to be a grown-up, and to make her own decisions, instead of having her parents pick what she wears, where they live, what they have for dinner, and where she goes to school. Then Mel gets the chance to travel to a magical world, where she can make her own choices and return all grown up. But what happens when you get older without living your life along the way? Enchanting adventures and magical mishaps abound as Mel grapples with what it means to grow up.
