Vanessa Michael Munroe--the fearless heroine of the New York Times bestseller The Informationist--returns in a gripping new thriller.

Eight years ago, five-year old Hannah was spirited out of school and into the closed world of a cult known as The Chosen. Ever since, followers of its leader have hidden the child and shielded her abductor. Now, childhood survivors of The Chosen who have escaped to make a life for themselves on the outside know here to find Hannah and turn to Vanessa Michael Munroe for help. Munroe reluctantly takes the job, and travels to Buenos Aires to infiltrate the cult and save the girl. Inducted in to a world unlike anything she has faced before, Munroe must navigate unpredictable members and their dangerous cohorts, the impatient survivors who hired her, and the struggle against her own increasingly violent nature so she can rescue the child before the window of opportunity closes and Hannah is lost forever.
