This was a really good book...there was a lot going on and a bit of it was above my head. I really liked Salander's character, she was intriguing and different than most characters...it made it really fun to read the parts about her. I felt more connected to her than any of the others.
I thought I had it figured our near the beginning, but I wasn't even close! The main mystery of the book (Harriet's disappearance) and the investigations were told perfectly so that you couldn't know for sure what the next twist would be. The part about the company they were trying to take down seemed like a sideplot (well, it was) but Larssen managed to pull it all together in the end.
I'm excited to read the other 2 books in the Millenium series!
