From the author of After the Crash comes a gripping new thriller about one woman-s descent into grief and madness after her ten-year-old son disappears without a trace. Maddi Libéri is a successful doctor living an idyllic life in the South of France. On the morning of her son-s tenth birthday, they walk to the beach together. The boy presses for a quick swim, but when the surf is too rough, she sends him off to buy a baguette instead. He never returns. Ten years later, Maddi stands at the spot where she last saw her son. A pilgrimage of sorts. And she can-t believe her eyes. There, standing at the water-s edge, is a young boy-and he looks exactly like her son. Same face, same suit-even the same birthmark. Rattled, Maddi becomes obsessed with the boy. She upends her life to get closer to him. And the more she learns about her son-s doppelgänger, the more unhinged she becomes. Dangerous secrets brought to light put people-s lives at risk, and plot twists reveal truths you-ll never see c
