Looooooved it! I liked the first book but it lacked some elements for me to make me really like it. It focused a lot more on Blomkvist than Salander. With the title I expected her to be more involved and learn more about her. The details were excessive about parts that had no later relevance and the ending was predictable and a bit disappointing. 
 Boy did Larsson turn it around with this one. I think he was just writing away at this point and couldn't stop his mind from thinking of all that he wanted to write and he just had to get it down. I feel like he just poured all passion in this book and had a handle for what he wanted with the series and her character, that he was confident in his work. The focus was on her the whole time and I got to learn so much about her character. She is one of the best characters created so it was very cool to learn more about her, a lot more in that. The details were very planned and all necessary. And it was action packed, so I actually felt a level of suspense and "I can't put this down" with this book. I just loved it! I loved her character from the get go so this book was a win. I'm on to watch the Swedish versions of the movies and plan to read the final book.
