Charlie Calloway has a life most people would kill for - a tight-knit family, a loyal set of friends, and top grades a privileged boarding school. But Charlie's never been interested in what most people want. Like all Calloways, she's been taught that she's different, special - better. So when her school's super-exclusive secret society extends a mysterious invitation, Charlie's determination to get in is matched only by her conviction that she belongs there. But their secrets go deeper than she knows. Charlie finds herself thrust into the centre of a decades-old mystery - one that implicates her family in not one terrible crime, but two. Uncovering their past may destroy everything she knows - or give her the answer she's always craved- Who or what was behind her mother's disappearance ten years ago?
