Amazon.com description: Product Description: The #1 international sensation, a mesmerizing and explosive thriller that reaches into the darkest corners of the human psyche and asks: How much suffering can a person inflict upon another before creating a monster? 

In a Stockholm city park, police find the tortured body of a youth. Then, they find two more, and it becomes clear that they are facing an extraordinary case—and an extraordinarily twisted killer. Detective Superintendent Jeanette Kihlberg heads the investigation, battling an apathetic prosecutor and a bureaucratic police force. She turns to the therapist Sofia Zetterlund for her expertise in psychopathic perpetrators, and under the pressure of the investigation, their lives become inextricably intertwined. As the two women draw closer to the truth about the killings, they begin to discover a hideous evil at work, and it’s much closer to them than they think. Mesmerizing and explosive, The Crow Girl is a tale of almost unfathomably heinous deeds and of the catastrophic damage, and the profound need for revenge, left in their wake.
