Eleven-year-old Killarney thinks school is boring. She’d much rather be exploring the wilderness around her Tasmanian hometown or helping her hairdresser mum. When strange things start to happen - ear-splitting screams in the dead of night and missing items found under the house - there’s even less chance of Killarney doing her schoolwork. She’s too busy solving the mystery.

Before long, Killarney discovers the culprit- a wild Tasmanian devil, denning under the house! Killarney is excited, but many of the locals are terrified. When rumours about dangerous devils begin spreading, Killarney is determined to protect her precious visitor.

But can she convince an entire town these wild creatures are worth saving?
