When a mysterious young girl arrives in the small New England town of Edgeport, it's up to criminal psychologist Audrey Harte to figure out where exactly she came from . . . but sometimes the past should stay in the past.
Thanksgiving is approaching, and Audrey Harte has a lot to be thankful for -- her mother has recovered from surgery, her relationship with Jake is solid, her father is relatively sober, and her career is evolving in an exciting direction. So when an 18-year-old girl turns up on her mother's doorstep, claiming to be the daughter Maggie Jones gave up for adoption, Audrey is amazed.
As Audrey helps the girl discover where she came from, people in the little town of Edgeport think she should leave the past alone, and they let her know through threatening messages and phone calls. Soon, Audrey realizes that it doesn't matter how well you think you know someone -- you don't know what they're capable of until their secrets are threatened. . .
