In many ways, a standard psychological suspense. It ticked the boxes for me - sister conflict, the older sibling an apparent suicide, the younger naive girl refusing to accept the police finding and deciding to investigate whether her sister's death related to a cold case she was investigating of a long-lost child. I didn't feel the twist was that unique and Sawyer oftentimes seemed to ignore obvious clues or avoid conversations with relevant “suspects” but the writing was good, the plot kept me engaged, and for a debut novel, it stayed true to the genre. A solid four stars. Thanks to Crooked Lane and NetGalley for providing me with an advanced reader copy.
