She does say that in the fourth novel Lisbeth Salander "little by little frees herself from her ghosts and her enemies." Gabrielsson says she will finish the book, but only once Larsson's family gives her complete rights to his work, which they inherited. Larsson died in 2004, before any of the three books in the Millennium series were published or made into films. The trilogy has sold over 20 million copies, and the three Swedish film adaptations of the existing books have made approximately $212 million worldwide.
Gabrielsson is not thrilled by how Larsson's books have been turned into a brand, and will likely be unimpressed with Sony and David Fincher's film adaptation starring Rooney Mara (pictured below in a W Magazine shoot, taking over from Noomi Rapace, who made the Lisbeth Salander character famous) and Daniel Craig, which makes key changes in both plot and character details.
Gabrielsson's book details how she and Larsson met and their times together at Expo, Larsson's anti-fascist publication, which he started in 1995. One reason the couple never married was the danger faced by Expo's contributors, who "moved around constantly to escape the Nazis who were harassing them."
