Are you going to read it? I'm not planning on it. When I finished reading the third book, I thought I had said goodbye to Lisbeth and Mikhail. I didn't think I would ever see them again. I don't think I can read it. I became too close to Lisbeth and Mikhail, it's not the same as a James Bond novel to me.
I'm not sure yet. I suppose it depends on how well it's received. I enjoyed Larsson's trilogy, so I'm not quite ready to say no. But I admit to being hesitant about reading a continuation by another author. Let's see what the critics and the readers have to say.
