Cassidy Blake's parents are "The Inspecters", a (somewhat inept) ghost-hunting team. But Cass herself can REALLY see ghosts after her near death experience. In fact, her best friend, Jacob, just happens to be one.
When The Inspecters head to haunted Edinburgh, Scotland, to host their new TV show, Cass—and Jacob—come along. In Scotland, Cass is surrounded by ghosts, not all of them friendly. Then she meets Lara, a girl with the same gift to see the dead. But Lara explains that their job is to send ghosts permanently beyond the Veil.
Cass isn't sure about her new mission, but she will have to learn fast. Cassidy's powers will draw her into an epic fight that stretches through the worlds of the living and the dead, in order to save herself.
