If you passed Alice on the street, you couldn’t help but smile. At how she holds hands with her husband, Jack, who she has been with since she was at university. At the adoring way she admires her three beloved boys, the centre of her universe. But if you looked very closely, you’d see how tightly she holds Jack’s hand, afraid to let go. You’d see how carefully she watches her boys, scared to look away. You’d see her smile fading in a matter of seconds, and the secret she hides behind her chestnut-brown eyes. She has told Jack that she ran away from home when she was younger – but she didn’t tell him the whole story. Her husband doesn’t know about the guilt she bears about the little sister she failed to save, the secret that torments her. Now, after a lifetime of fresh starts, Alice receives a message spelling out her past. Everything she cherishes, the world she has lovingly built, threatens to collapse in on her. Without her family, she is nothing – and Alice will stop at nothing to save them.
