From the author of the #1 international bestseller The Girl in the Spider's Web comes the newest book in the Millennium series, which began with Stieg Larsson's The Girl with the Dragon Tattoo.

Lisbeth Salander is in Flodberga prison sentenced to two months after she went to extreme lengths to save a boy's life. There, she witnesses the torture of a young Bangladeshi woman whose plight draws her into a deeper conflict. Then, her old guardian delivers news that might shed light on her own troubled past, a secret experiment known as the "registry." She enlists her friend Mikael Blomkvist, crusading editor of Millennium magazine, to help her look into the study. Once Salander is released, she devotes her time to uncovering the truth in the case that landed the Bangladeshi woman in prison, and Blomkvist continues his search into Salander's background. Together Salander and Blomkvist continue their fight for justice in this exhilarating, full-tilt novel.
