Natchez Trace Park Ranger Emma is stunned when shots are fired at her as she returns to her office one night to grab a file. She is further upset when her ex-fiancé Sam, the law enforcement district ranger, will be working with her on the ensuing investigation. Emma was preparing to inventory a historical slave burial site when one of the graves was robbed. To make things worse, the DNA on a remaining bone fragment links to Emma. Her twin brother has been missing for years, and Sam was one of the last people to talk to him. The records for her brother's case have disappeared, and Emma, Sam, and her parents are determined to finally find out what happened, an effort complicated by the fact that Emma is in danger from a threatening stalker. Emma and Sam must work through both these cases and their lingering feelings. Deepened by Bradley's fascinating illumination of the park system, this smart, well-written tale of romantic suspense follows Standoff (2020) in a unique series that will appeal to fans of Nevada Barr.
