Her one mistake

But when her three kids are all safe and sound at the school fair and Alice her best friend Harriet's daughter is nowhere to be found Charlotte panics. Frantically searching everywhere Charlotte knows she must find the courage to tell Harriet that her beloved only child is missing. And admit that she's solely to blame. Harriet devastated by this unthinkable unbearable loss can no longer bring herself to speak to Charlotte much less trust her. Now more isolated than ever and struggling to keep her marriage afloat Harriet believes nothing and no one. But as the police bear down on both women trying to piece together the puzzle of what happened to this little girl dark secrets begin to surface--and Harriet discovers that confining in Charlotte again may be the only thing that will reunite her with her daughter."-- Jacket.
