Salander is confined to the secure unit of a women's prison, with violence all around her, but for a hacker of her skills, there are no boundaries.

She gives Mikael Blomkvist a lead that could give him an important exposé for Millennium magazine, an investigation into a sinister experiment that may also unlock the mystery of her harrowing childhood.

The dragon inked into Salander's back is a constant reminder of her pledge to fight the injustice she finds on every side, and she will discover the truth, whatever the cost.
