Mysterious fires. A haunting past. A secret file. Three years ago, Olivia Callahan endured an assault that resulted in a devastating brain injury. She survived, but she couldn't remember anything about her life or who she was. Now, she's determined to build a bridge between the past she lost and the life she must reclaim. When Olivia crosses paths with Private Investigator Tom Stark, she is drawn to the investigative field, and becomes his intern. She finds a heavily redacted, forty-five-year-old file locked in his desk drawer that mentions her mother as a young woman. Why had her mentor hidden the file from her, and why had he never mentioned a case involving her mother? As Olivia moves forward with her fledgling career, a string of mysterious fires moves through the community, puzzling the Baltimore Arson Investigative Unit. One of the fires strikes Olivia's beloved farmhouse in rural Maryland. Now, in addition to uncovering the secrets bound within the redacted file, she becomes convinced that the fires happening around the area are disturbing calling cards...and they're meant for her.
