In their holiday home, a stone’s throw from the beach, Elizabeth dials the police with trembling hands. "My little boy, he’s missing."

Elizabeth is Joe’s foster mother, but she loves him like her own. The five-year-old, who adores superheroes and watching the birds outside, is the child she has dreamed of. As she looks into the garden, where he was playing just moments ago, her heart feels like it has been ripped from her chest.

She was meant to save Joe from his birth mother who almost harmed his chances at life. The woman who has been trying to desperately get him back.

She was meant to protect Joe from her husband. The man who, right now, lies to the police, saying he was making breakfast when Joe disappeared. Who squeezes her shoulder, ordering her to be quiet.

She was meant to look after Joe. They are just footsteps from the ocean, and little Joe can’t swim.

Then Joe’s tiny blue sandal is found in the water. If the worst has happened—the unimaginable—Elizabeth will never forgive herself. Because what if the secret she has been keeping for years, the guilt eating her alive, has somehow hurt her little boy?

It’s time to tell the truth—even if it means losing the child who is her whole world. Even if it could be the death of her.

A totally addictive, twist-packed psychological thriller about family secrets, a marriage on the edge, and the deadly line between love and hate. Perfect for fans of Lisa Jewell, Liane Moriarty, and Freida McFadden.
