Zoe Emmerson has a secret, one she’s kept for years. Her quiet world is shaken when her past finally catches up with her: the investigation into the murder of a six-year-old neighbour is re-opened thirty years after the fact, threatening to destroy her and everyone she’s fought so hard to protect.

She was just a child when it happened, scared and confused, and she’s never been entirely sure what she saw. But she kept her brother’s suspected involvement in the murder from the police, and the knowledge that she withheld a crucial piece of information haunts her.

As the past collides with the present, Zoe is forced to face a most difficult truth.
