When her parents’ carriage takes a leap off Gibbett Bridge – an accident for which there appears to be no explanation – Mallory Vayle is taken in by a strange aunt and brought to her new, and very spooky, home. Aunt Lilith, a charlatan psychic, is quick to monetise Mallory’s prodigious skills in talking to dead people and starts to advertise grand seances in her spiritual news sheet. The ghosts of her parents also take up residence in the house but are cruelly snatched away by the shadow of Hellysh Spatzl, the grimmest, wickedest necromancer in all of history. To get them back, Mallory will have to learn how to use the talents she hates and raise the old hag from the dead. Her teacher? A talking skull called Maggoty, who wants some favours in return for his help.
