To be honest the ordinary cover did not promise what ended up to be an intense and gripping page-turner. As much as I am a fan of good old psychological thrillers I don't fancy particularly graphic and gory ones and this one hit the right spot for me. Three little girls: two of them nasty, spoilt and sassy and the third one - miss goody two-shoes, with low self-esteem which turns her into a perfect victim even to her younger sister and her best friend. But all of them consumed by jealousy, urging them to play tricks to one another that escalate out of control. The author Jane Corry was completely new to me but I give her credit for bringing forward difficult subjects like life in prison with its hierarchy of crimes, living with disabilities and the frustration for not being able to express your thoughts and needs, the root of self-harming and the guilt that eats rape victims. The story goes back and forth in time changing the perspective from one sister to the other. Kitty - who is living in a care home after a severe brain injury incident, bound to a wheel-chair with a brain and body not willing to cooperate with each other. However, despite her disability I did not develop a liking for her until the very end when a more human side transpired. And Alison who is distraught by guilt and the secret she has to carry around, always on the lookout for somebody or something from the past ready to catch up with her and absolve her of her sins. She seeks atonement by neglecting her personal life and resorting to self-harm and is totally the sister I empathise with. Too much food for thought and too many secrets that come to light one after the other and still another one remains.
