In the middle of tending to the everyday business at her vintage-clothing shop and sidestepping her married boyfriendâ€™s attempts at commitment, Iris Lockhart receives a stunning phone call: Her great-aunt Esme, whom she never knew existed, is being released from Cauldstone Hospitalâ€”where she has been locked away for more than sixty-one years. Irisâ€™s grandmother Kitty always claimed to be an only child. But Esmeâ€™s papers prove she is Kittyâ€™s sister, and Iris can see the shadow of her dead father in Esmeâ€™s face.Â Esme has been labeled harmlessâ€”sane enough to coexist with the rest of the world. But she's still basically a stranger, a family member never mentioned by the family, and one who is sure to bring life-altering secrets with her when she leaves the ward. If Iris takes her in, what dangerous truths might she inherit? A gothic, intricate tale of family secrets, lost lives, and the freedom brought by truth, The Vanishing Act of Esme Lennox will haunt you long past its final page.
