We meet Liesl the night after the day her young father has died. That same day she is visited by a ghost, Po, an eight year old boy who lives on the other side, the territory between life and death that runs parallel to the living world. Po has come to tell her that her father is stuck on the other side, and that she is the only one who can help him cross over. A couple of wooden boxes. Some ashes. Some magic dust. A ghost, its pet, and a boy who forgot to wear a hat in the cold. From these seemingly odd, random characters Oliver weaves the enchanting story of how, with the aid of Liesl, these elements come together over the course of one week to restore love and luster to a world gone grey and heartless.
