Some secrets can be deadly.... Stepping into the darkened hospital clinic, Mackenzie (Mac) Dodd hears the faint click of a revolver before spotting the barrel pressed against the young marine’s temple. Unable to stop the suicide, Mac blames herself. Encouraged by her idealistic neighbor, she posts the incident on Silent Survivor, a blog in which she encourages veterans with PTSD to share stories. When the marine’s widow reveals there may be more to her husband's suicide, Mac begins an investigation, risking her life to expose secrets and betrayals as she uncovers the unintended consequences of covert government research.
