There are three things no-one can prepare you for when your daughter goes missing: you are haunted by her memory day and night; even close friends can't understand what you are going through. Only in a group with mothers of other lost children can you find real comfort. But as the parents gather to offer each other support in the wake of another disappearance, a crack appears in the group that threatens to rock their lives all over again. Welcome to the club no one wants to join. "A taut, psychologically gripping, gut-wrenching thriller from one of my favourite writers." (Lisa Jewell). "Head and shoulders above the rest. Gripping." (Daily Mail). "An astonishingly good psychological thriller that you won't want to miss.' (C L Taylor). "We guarantee you'll be gripped." (Closer).
