The book: The Child by Fiona Barton
The hook: When the decades-old bones of an infant are discovered at a construction site in London, journalist Kate Waters makes it her mission to uncover the child's identity. Barton weaves an intense mystery with each passing page, peeling back layer upon layer of familial drama, discord, and shame as Kate untangles the complicated tale.
Fear factor: The only thing scary about this book is its reminder of just how far a human being will go to protect a secret.
