When Jools Trevaller's parents announce that the city is becoming too dangerous and that they're moving to a rundown former staging inn in the small town of Waterloo Creek, Jools is furious. But the house is already occupied by the ghost of a girl called Elly Lockett, who died mysteriously in the nineteenth century. Only Jools can see Elly, and they form a strong friendship as they seek to understand exactly how and why Elly died and where her body lies. Neither realises that once the mystery is solved, they'll be parted forever.
