“A wonderful twisty novel of family and secrets—the perfect summer read.”—Kate Morton, bestselling author of Homecoming

Notting Hill, London: One May evening, seventeen-year-old Maggie Parker's mother walks out of their front door and doesn't return. With her little brother in tow, desperate to find their mother, Maggie is drawn into a labyrinthine world of secondhand shops and shadowy figures, far from the grand townhouses in her comfortable neighborhood.

As Maggie struggles to maintain a stable life for herself and her brother, she befriends Wolf, another young person also living on his wits alone. But can he help solve the mystery of her mother’s disappearance—or will her growing feelings for him just cause her further pain, upending her life even more? When she discovers that her beloved house now holds a dangerous new secret, and Wolf is involved, Maggie, heartbroken, makes her escape.

Twenty-one years later, in her Paris apartment, Maggie gets a phone call that shatters her hard-won new life. While in London, the incoming owner of the Parkers' old Notting Hill house is excavating the basement, unaware of what might lie beneath—and the clock starts ticking on buried secrets.
