Clutching my husband's hand, I screech with delight as the rollercoaster loops through the air. I feel young and free for the first time in years, but as we roll to a stop and I look for our three beloved children in the crowd, I panic. I can only see two. Where is my daughter?

Today was meant to be special. A final fun family day out before five-year-old Summer joins her big siblings at school. But in an instant, we're plunged into a nightmare. We scream her name as we frantically search the amusement park for a glimpse of her flaming red hair.

When the police ask about strangers, grudges and enemies, I have no answers, just questions. Why did I think I could leave my children alone, even for a minute? What kind of mother am I?

I feel in my heart that Summer is out there somewhere. But as I obsess about finding her, my family is falling apart. My eldest daughter Merritt is withdrawn. My son Gus is angry. And after seventeen years of marriage, my husband has never felt more like a stranger. Where does he go when he says he's working late? Who is he constantly messaging?

I must fight to hold my family together, but I'm terrified Summer's disappearance will destroy us all. Will I ever forgive myself for letting her out of my sight? Will I ever hold her tiny hand in mine again?

A completely gripping and emotional page-turner about every parent's darkest fear. Perfect for fans of Jodi Picoult, Jojo Moyes and Kate Hewitt.
