We Are All Guilty Here by Karin Slaughter

Welcome to North Falls. A small town where everyone knows everyone.

But nobody knows the truth. Emmy Clifton thinks she knows her neighbours. She's wrong.

She thinks it’s just another hot summer night like any other. She's wrong. When her best friend's daughter asks for help, she thinks it’s just some teenage drama.

She’s never been more wrong in her life. As the town ignites in the wake of the girl's disappearance, Emmy throws herself into the search. But then she realises: You never really know a town until you know its secrets.
