To unlock her secret, you must tell yours.

Holly Mayhew has the perfect family. But when she notices her seven-year-old daughter, Marley, becoming withdrawn and secretive, she sets up a solution. Holly creates a "worry box," where Marley can post her innermost thoughts.

But as the worry box fills up, Marley's notes threaten everything Holly thought she knew about her daughter.

What is Marley not telling her, and why is she so scared?

Holly's past is shrouded in a mystery of its own, and she must confront her own secrets - secrets kept locked away for years - if she's to help her daughter.

Once the truth is out... there's no going back.
