On the way back from Spain, I finished reading The Girl Who Kicked the Hornets' Nest; it was a great diversion for the eight flight from Madrid to Philadelphia. This is the third book of Stieg Larsson's published trilogy. I finished the first book in late June and the second book on the outbound leg of the trip to Spain.
This book does a good job of tying up all of the loose ends created at the end of the second book as well as continuing to fill out the Lisbeth Salander character.
I enjoyed all three of the books. I seldom read a series of books consectively. Normally, I would read something else in between. The story was compelling enough that I read all three books without a break. While some people have said that they liked the second and third books less than the first, I got more engaged with each book.
Larson died before the books were published. It has been reported that he left about three quarters of a fourth novel on a notebook computer. Synopses of the fifth and sixth in the series apparently also exist. The series was intended to contain an eventual total of ten books.
