Think Harlan Coben, meets Lisa Gardner with a dose of Haylen Beck. This is an epic US thriller with a killer hook.
You're woken early by the doorbell. It's a young girl, the daughter of the love of your life. She's scared, covered in blood, she says her mother is hurt.
You let her in, try to calm her down, tell her you're going to get help. You reach for your phone, but it lights up with a notification before you touch it.
It's an Amber alert - a child has been abducted by a dangerous suspect.
The child is the girl standing in front of you.
The suspect? You.
