Blood Memory.

Forensic expert "Cat" Ferry is suspended from an FBI task force when a world class odontologist is inexplicably stricken with panic attacks and blackouts while investigating a chain of brutal New Orleans murders. Returning to her Mississippi hometown, Cat finds herself battling with alcohol, plagued by nightmares, and entangled with a married detective. Then in her childhood bedroom, some spilled chemicals reveal two bloody footprints...and the trauma of her father's murder years earlier comes flooding back. Facing the secrets of her past, Cat races to connect them to a killer's present day violence. But what emerges is the frightening possibility that Cat herself has blood on her hands.
