Will the stories be published? Well, they have a lot of strikes against them:
They're short stories, not novels.
They're science fiction.
They were written when when Larsson was only 17.
They were rejected by the Swedish magazine Jules Verne.
The final decision as to whether or not to publish the stories rests with Larsson's estate, but there's really no question that they will make their way to bookstores eventually. Details are here.--David E
