Roxanne MacFarlane is the Extractor--a former CIA agent who specializes in rescuing people from dangerous situations. She lives on the edge and works outside the law, but desperate families know she's the only operative who can bring their missing loved ones home. Driven by guilt over the loss of her sister to a polygamous cult, she will stop at nothing to save her clients.
When Dave and Jenny Carson ask her to find their daughter, Mia, and extract her from a charismatic cult leader who preys on young women with guilt issues, Rox is eager to help them. But the experimental treatment she just started in order to improve her atypical brain patterns forces her to face conflicting newfound emotions while working feverishly to find the secret compound and craft a strategy to get Mia out.
When the bodies of young women who match Mia's description turn up, Rox must fast-forward her plans. But the situation is more complicated and dangerous than she realizes, and her own life is soon in jeopardy. Can Rox save Mia and bring down a ruthless predator before more young women fall victim?
