Young American Aliya Scott travels to Tanzania to help children with her condition. There, people without pigment in their skin are called "zeru-zeru," it means "ghost," and they are believed to possess magical powers. When Aliya goes missing, her father sets out on a mission to find her. He soon discovers that she was up to more than teaching the alphabet and handing out sunblock. With each step he learns more about his daughter and a country rooted in ancestry, rich with resources, full of mystery and conflict, and a world of witchdoctors and foreign plundering, with little transparency and less justice. From the shadow of the Mukuyu tree he follows her "ghost" to the head of the dragon in Europe. But will he reach Aliya before it is too late?
