In the middle of tending to the everyday business at her vintage clothing shop and sidestepping her married boyfriend's attempts at commitment, Iris Lockhart receives a stunning phone call. Her grandmother Kitty was not an only child, and Iris's great-aunt Esme, whom she'd never heard of, is suddenly being released from a hospital where she's been locked away for decades. If Iris takes her in, what dangerous truths might she also inherit? "At the heart of this fantastic new novel is a mystery you want to solve until you start to suspect the truth, and then you read on in a panic, horrified that you may be right."—Washington Post
