Since the signing of 'The Treaty' four hundred years ago the Humans of the Cauldron and the Vampires of Storm Hill have lived alongside one another in comparative peace. However, following the rebellion against Lord Harbinger, Cauldronians are disappearing. Many Elders believe Vampires are kidnapping their kin to feast on them while others are convinced they are being taken to work as slaves in Vampire factories, mills and mines. The truth is unimaginably worse. To keep safe, the Carter family move in with Nana Lyons, despite Charlie Carter being terrified of what he witnessed going into her coal cellar as a child. The stakes are raised to new heights when Jed, Charlie's little brother, goes missing.
