Brought to you by Penguin. Everyone is talking about Grace Vermuyden's family. Once it was for all the right reasons - now it's for all the wrong ones. Grace wants the world for her two daughters - especially after her own dysfunctional upbringing. Mia is wonderfully one-of-a-kind, even if her imagination does run a bit wild. Lilly is everyone's golden girl, with a glittering future ahead of her. Then Lilly collapses suddenly at school, and Grace's carefully-ordered world is turned upside down. Lilly was the one she didn't have to worry about. But as dark rumours swirl around the school gates and things start to spiral out of control, everyone in their tight-knit community has their own theory about what happened. Grace is shocked to discover her eldest daughter had a hidden life, and begins obsessively looking for clues. Which is when she takes her eyes off Mia. Grace thought she had a happy family. But what if she never really knew her daughters at all?
