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.
