Caroline Cashion is stunned when an MRI reveals that she has a bullet lodged near the base of her skull. It makes no sense: she has never been shot. She has no scar. When she confronts her parents, she learns the truth: she was adopted when she was three years old, after her real parents were murdered in cold blood. Caroline had been there the night of the attack, and she’d been hit by a single gunshot to the neck.
