Cuckoo / Sophie Draper.

"Have you been bad enough? After her stepmother's sudden death, Caro returns to her childhood home, a now-empty farmhouse in Derbyshire. But clearing through her stepmother's belongings unearths memories Caro would rather stay buried. As snow descends, trapping Caro in the strange village, where the neighbours stare and whisper about her, Caro's past will catch up to her with deadly consequences. What is it about the summerhouse that makes her shiver? Who is the young boy she seems to remember playing with? And why did her stepmother taunt her with a haunting fairy tale about two sisters, enticed to commit a terrible act? As Caro digs into the dark corners of her past, she starts to realise that she has been bad. More than bad enough...“--Provided by publisher.
