Her child is missing. And she'd do anything to find her...

I stare at the little girl in the photo, her big eyes looking straight at me. 'Please,' the woman pleads holding the photo up. 'You have to help me. No one else will.'

Every Friday Mercy Hamilton goes to the same supermarket. She doesn't go to buy groceries, instead, she shows a fading photo of a little girl to anyone who'll look - begging for help to find her daughter.

One Friday, Erica Fielding comes across Mercy, and touched by her story, Erica agrees to help.

As Erica is drawn deeper and deeper into Mercy's life, she discovers there is no record of Mercy's daughter. In fact, there's no record of a child at all.

But who is the girl in the photo if not Mercy's missing daughter? And what danger will Erica find herself in by pursuing the truth?

The pulse pounding psychological thriller that will leave you totally breathless. Perfect for fans of Gone Girl, Lisa Jewell and Shari Lapena.
