Lisbeth Salander, the girl with the dragon tattoo, the brilliant hacker, the obstinate outsider, the volatile seeker of justice for herself and others-even she has never been able to uncover the most telling facts of her traumatic childhood, the secrets that might finally, fully explain her to herself. Now, when she sees a chance to uncover them once and for all, she enlists the help of Mikael Blomkvist, the editor of the muckraking, investigative journal Millennium. And she will let nothing stop her-not the Islamists she enrages by rescuing a young woman from their brutality; not the prison gang leader who passes a death sentence on her; not the deadly reach of her long-lost twin sister, Camilla; and not the people who will do anything to keep buried knowledge of a sinister pseudoscientific experiment known only as The Registry. Once again, Lisbeth Salander and Mikael Blomkvist, together, are the fierce heart of a thrilling full-tilt novel that takes on some of the most insidious problems facing the world at this very moment.
