Scarred forever by the hideous and unforgivable sins of her father, the antisocial, technologically brilliant computer hacker, Lisbeth Salander, finds herself ridding Stockholm of sadists who hate women.
It's been three silent years since she last saw her old journalist friend, Mikael Blomkvist, after the events of The Girl with the Dragon Tattoo (2011), and now, Lisbeth is with her back to the wall, hunted down like prey for stealing Project FireFall: a powerful tool designed for the Americans, developed to breach and control most online defence systems.
Now, as the NSA, the Swedish Security Service, and deadly Russians are hot on her trail, more and more, Lisbeth's horrible past comes back to haunt her, and no one in this world is safe if the state-of-the-art computer software falls into the wrong hands.
What does the future have in store for Lisbeth Salander, the girl in the spider's web?
