Half of the Puzzle

During a qualifying round of golf, sixteen-year-old Penn hits her shot into the adjacent cemetery and discovers an unearthed grave and a vial of TR-97. When she learns the drug is a treatment for PTSD, she thinks of her dad and vows to meet the disgraced psychiatrist who developed the therapy.

With help from her friends, Penn uncovers more information about the drug, convincing herself it will cure her dad and reunite her parents. But, as she faces increasing threats from others who covet the vial, Penn must choose between helping her dad and saving herself.
