Another great book from Harlan Coben. A stand alone thriller. After serving abroad Maya returns to nightmares over what happened. Her sister is murdered. Then her husband is murdered. Her friend gives her a nanny-cam to check on her two year old daughter lily with the childminder. Checking the nanny-cam she sees her dead husband with their daughter. So is he still alive? Or is her mind playing tricks?

No spoilers but the action gallops along and is a great read.
