Girl Who Kicked the Hornet's Nest by Stieg Larsson

This picks up where "Girl Who Played with Fire" left off - Lisbeth Salander, who was found by Blomkvist shot in the head is alive after having brain surgery. Though still the prime suspect in three murders in Stockholm, she is convalescing under armed guard.  Meanwhile Mikael Blomkvist works to unravel the decades-old coverup surrounding the man who shot Salander: her father, Alexander Zalachenko, a Soviet intelligence defector and longtime secret asset to Säpo, Sweden's security police. While Blomkvist and Listbeth primarily communicate via online the story flows as both come to terms with the truth.

It took me 2 months to read this book as the first 350 pages just were difficult for me to process.  We are introduced to many new characters while we continue to follow old ones.  Plus since I knew it was the final book I think I just didn't want to finish it.  But once I got to about 350 I just couldn't put it down.  Thankfully it was over a long weekend so I was able to finish it and I felt very happy by the ending.  While I'll miss this series I felt like it ended where I would like it to be.
