The Girl Who Played with Fire by Stieg Larsson

The fierce heart of this novel is Lisbeth Salander: the troubled, wise-beyond-her-years genius hacker who teamed up with crusading journalist Mikael Blomkvist in The Girl with the Dragon Tattoo.

This time, Lisbeth is implicated in a murder: her fingerprints found on the weapon used to kill two journalists the night before their explosive story about sex trafficking in Sweden was set to be published. Now, while Blomkvist—alone in his belief in her innocence—plunges into his own investigation of the slayings, Lisbeth is drawn into a hunt in which she is the prey, and which compels her to revisit her dark past in an effort to settle with it once and for all.
