Still recovering from Owen's attack and still learning to control her new power over fire, Ember just wants to relax and enjoy her favourite time of year-Halloween. But when the school party is interrupted by the sudden death of a student, it becomes clear that there's a new threat lurking in the academy. The school's ghost story is more than just legend- it's real. And Haunting Harry has come back from the dead to punish students he deems to be misbehaving. Desperate to keep him from killing more students- especially Reid, who is a perfect target for the mischief-seeking authoritarian spectre- the vampires and Sherry must team up with a suspicious newcomer to the school, tackle the problem of killing a dead man, and fight against an old enemy. For Ember, Halloween has never been so terrifying.
