A thrilling debut spooky mystery to send shivers down your spine, for fans of Michelle Harrison and Abi Elphinstone.

'I am tired of Eve Wersocki Morris being the best-kept secret in children's literature. I want everyone to be reading her mysterious and mesmirizing books. Please do your part.' Lemony Snicket, author of A Series of Unfortunate Events

'The whistling had started on their first night. At first, Layah thought it was bird song - a high thin sound which became a melody, rising and falling. And each night, it returned.'

Strange things have been happening to Layah and her younger sister, Izzie, ever since their mother dragged them to a rain-soaked cottage miles from anywhere in the Lake District: there is a peculiar whistling at night, a handful of unusual feathers appear on their doorstep and there are murmurings of a shadowed woman in the forest. And their mother is behaving very oddly. Layah is mourning the loss of her dear grandmother in Poland - and can almost hear her Babcia's voice telling her the old myths and fairy tales from that magical place.

And as the holiday takes on a dark twist, Layah begins to wonder if the myths might just be real.

'A deliciously spine-tingling story with sisterhood at its heart. I loved it.' A.F. Steadman, author of Skandar and the Unicorn Thief
