Marnie Logan often feels she is being watched. It's nothing she can put her finger on - a whisper of breath on her neck, a shadow in the corner of her eye - and now her life is frozen. Her husband, Daniel, has been missing for more than a year. Depressed and desperate, she seeks the help of psychologist Joe O'Loughlin. Then she discovers a book packed with pictures and interviews that Daniel was preparing for Marnie. It was supposed to be a celebration of her life - but it's not the story anyone was expecting.
