Cass County, Minnesota: A sheriff's deputy steps out of a diner on a rainy summer evening, and a few minutes later, he's lying dead in the mud. When BCA agent Kirk Stevens arrives on the scene, he discovers local authorities have taken into custody a single suspect: A hysterical young woman found sitting by the body, holding the deputy's own gun. She has no ID, speaks no English. A mystery woman. The mystery only deepens from there, as Stevens and Carla Windermere, his partner in the new joint BCA-FBI violent crime task force, find themselves on the trail of a massive international kidnapping and prostitution operation. Before the two agents are done, they will have traveled over half the country, from Montana to New York, and come face-to-face not only with the most vicious man either of them has ever encountered- but two of the most courageous women. They are sisters, stolen ones. But just because you're a victim doesn't mean you have to stay one.
