Caitlin Girard's murder occurred twenty-one years ago. The horror haunted her fourteen year-old sister Gabby, driving her into a career at the FBI. Her job in limbo when the Bureau suspends her, Gabby returns to her childhood home. Working the cold case in Brecksville, Ohio, where she has no authority, won't be easy. Difficulties, however, have never stopped Gabby. She talks her way into an unpaid position with the Cuyahoga County Prosecutor's office. Retired detective Matt Peterson becomes Gabby's ally in her grim quest to discover who killed Caitlin, and buried her beside the Cuyahoga River. While leads are few and clues are fewer, Gabby suspects that whoever killed her sister didn't stop with one victim. Will the forensic evidence she's sent to Quantico give her enough proof to arrest the killer before another young woman's body is found buried on the bank of the Cuyahoga?
