A rising star in the CIA, Erin Baker is driven by tragedy from her past. When she was a child, her eight-year-old sister, Claire, was kidnapped. Though Claire was miraculously found, she was changed forever. As was Erin, who now just might get what she's always wanted: the chance to make a difference in someone's life. But she must be willing to risk everything she holds dear. When a child disappears near her home, Erin is certain there is a link to her sister's cold kidnapping case. She meets Alex Donovan, an FBI agent on the hunt to find the missing boy, whose record for locating missing children is unquestioned. Suddenly Alex and Erin find themselves on a desperate pursuit - from the streets of America's most peaceful neighborhoods to a horrifying underworld where children are stolen and trafficked. And as they get closer to the truth, they make their own lives, and the lives of everyone they love, into perfect targets for a killer.
