Marley has always been a girl who knows what she wants, and she wants nothing more than to save her father and to get her best friend back. Unfortunately, both of those jobs are out of her hands, and her powers have mysteriously stopped working. But Marley has never been able to sit around and do nothing. When a new voice pops up in her head, telling her to gain control of her powers, Marley intends to do just that. Only she doesn't know how. She doesn't even know why they've stopped working. What she does know is that more than one soul will be lost if she doesn't find a way to make her powers work. Follow the adventures of Marley and her friends in this magical follow-up to Piggybacker, book one in the Vessel of Lost Souls trilogy.
