But now she’s missing and none of the locals seem to care, including the police. They think a message Claire received is proof she’s safe. But Claire knows for a fact that’s impossible. What will she have to risk to find out the truth? Who are the locals protecting? And what does it have to do with another girl who went missing five years ago? It’s going to be a summer she’ll never forget. An unputdownable psychological thriller summer read from the #1 bestselling author, for fans of Heidi Perks, Claire Douglas and Lucy Clarke.
