From the CBC:
The Swedish publisher of the best-selling The Girl With the Dragon Tattoo trilogy said Tuesday it has hired an author to write a sequel to the series by Stieg Larsson, who died in 2004.
Norstedts said it signed a contract with David Lagercrantz, the author of I am Zlatan, a biography of Zlatan Ibrahimovic, the captain of Sweden's soccer team, to write a new novel about journalist Mikael Blomqvist and hacker Lisbeth Salander that is scheduled to be published in August 2015.
Eva Gabrielsson is quoted as calling the endeavor "tasteless", and I'm inclined to agree with her. (Of course, we'll probably never know whether or not her feelings would be the same if she owned the rights...)
I'll most likely skip it in favor of getting caught up on Carol O'Connell's books. LONG LIVE KATHY MALLORY.
Relatedly, from a PW interview with O'Connell:
Tell us a little about the genesis of Kathy Mallory.
Whenever I go out on tour, someone will ask if Mallory is autobiographical. It always startles me. I like to think that I show no markers for a sociopath. Mallory is purely a work of imagination. This answer disappoints everyone.
