The wayward girls / Amanda Mason.

"1976. Loo and her sister Bee live in a run-down cottage in the middle of nowhere, with their artistic parents and wild siblings. Their mother, Cathy, had hoped to escape to a simpler life; instead the family find themselves isolated and shunned by their neighbours. At the height of the stifling summer, unexplained noises and occurences in the house begin to disturb the family, until they intrude on every waking moment. Now: Loo, now Lucy, is called back to her childhood home. A group of strangers are looking to discover the truth about the house and the people who lived there. But is Lucy ready to confront what really happened all those years ago? "--Publisher.
