ly desperate search for their missing daughter in "a clever, chilling thriller that is also unexpectedly moving" (Shari Lapena, New York Times bestselling author of Everyone Here Is Lying)

"Imran Mahmood is the only author writing about a missing person who deals with grief this well. I loved it."--Gillian McAllister, New York Times bestselling author of Wrong Place Wrong Time

Someone is guilty.

For the last seventeen years, Harry and Zara King's lives have revolved around their only daughter, Sophie. One day, Sophie leaves the house and doesn't come home. Six weeks later, the police are no closer to finding her than when they started. Harry and Zara have questioned everyone who has ever had any connection to Sophie, to no avail. Except there's one house on their block--number 210, across the street--whose occupant refuses to break his silence.

Someone knows what happened.

As the question mark over number 210 devolves into obsession, Harry and Zara are forced to examine their own lives. They realize they have grown apart, suffering in separate spheres of grief. And as they try to find their way back to each other, they must face the truth about their daughter: who she was, how she changed, and why she disappeared.

Someone will pay.

Told in the alternating perspectives of Harry and Zara, and in a dual timeline between the weeks after Sophie's disappearance and a year later in the middle of a murder trial, Imran Mahmood's taut yet profoundly moving novel explores how differently grief can be experienced even when shared by parents--and how hope triumphs when it springs from the kind of love that knows no bounds.
