The Vance estate rises from the coastal fog like a tomb. Behind its locked doors and forbidden west wing, a family has been hiding secrets for decades. Claire Brennan found those secrets. Now she's dead. Her twin sister Nora takes her place—pretending to be the perfect caregiver while hunting for the truth. But the Vances are watching. Dr. Ross, the family physician, controls everything with prescription pads and threats. Marcus, the younger brother, drinks to forget his sins. Julian, the heir, loved Claire and might be the only honest person in the house. Someone pushed Claire off those cliffs. Someone is hiding the evidence. And someone is determined to make sure Nora never leaves. The Replacement is a twisty, atmospheric psychological thriller perfect for fans of The Woman in the Window and Rebecca.
