Full of suspense, mystery and humour, the books in this series follow Allie as she investigates a number of possibly paranormal events with a mix of logic, intelligence and teenage attitude. Who is haunting the cabin? After Eglantine vanished, I thought I was through with ghosts. Then I went on a school excursion to Hill end and found myself investigating a whole bunch of them. First there was the ghost of Granny Evans, pacing around the museum. And Eustace Harrow smashing things up in Taylor's Cottage. But when two of my classmates disappeared, I realised things were about to get serious.
