This is a book I almost gave up.  I listened to it on audio, and a few hours in I felt like I was still listening to background and set-up and was anxious for the story to get started.  Thankfully, once it got rolling it was a snowball I couldn't stop. Mikael Blomkvist and Lisbeth Salander are very interesting characters... very alike in some ways, polar opposites in others.  I spent a great deal of time wondering how their stories would be tied together, and I wasn't disappointed when they eventually were. The mystery of Harriet's disappearance was also very interesting, and the whole story is nothing you would ever expect when the investigation begins. I just had a couple of problems with it... the author tends to refer to everyone by their last name, which is much harder for me to follow.  For some reason, I just don't remember last names as well as first names, so every time someone was mentioned that we hadn't heard of in a while, I had to think for a minute about who they were talking about.  Also, there's a bit of a loose end with the Harriet investigation that I was expecting to be tied up that never was. I was expecting a small twist that never came.Overall, I quite enjoyed this and look forward to reading the next two (assuming the third makes it through translation to English). The ending to this one was sad in a way I didn't expect, and I'm anxious to see what it means for Blomkvist and Salander. If you start reading this and struggle a bit through the beginning, just stick it out... It gets so much better!
