All is not well with the Hurst family. There is gentle teenage daughter Violet, whose experiments with fasting and drugs land her in a psychiatric ward; eight-year-old Will who is smart, funny and caring but has already been labelled autistic and is being home-schooled; and mother Josephine, whose subtly controlling and seemingly innocent manoeuvres may just be the source of everyone else's despair. And then there's Rose, the sister who got away. Tired of Josephine's interferences, Rose ran away from home years earlier and hasn't been heard from since. But as her mother's intentions become more terrifyingly clear, Violet begins to wonder whether something far, far worse happened to her older sister.
