This book takes us back to Zombay, the imaginary country created by William Alexander in "Goblin Secrets." We are now introduced to a brave girl names Kaile, who dreams of pursuing music. Her dream seems to come true one day when a goblin gives her a flute made of bone. However, she quickly realizes that when you touch it, something terrible happens: she loses her shadow. In the great kingdom of Zombay, when someone loses their shadow, they are considered to be dead. Regardless of the fact that she is moving and breathing, her parents soon kick her out of the house since they believe she is haunting them. Not only must Kaile find a way to revert back to how things were before, but she also must find the melody that allows her to save people from a flood that threatens to destroy all of Zombay."
