<i>The Girl Who Played with Fire</i>
Read this on the plane during my recent trip to DC. It started off slow. Very slow. Slower than the first one even. Once the actual plot was established (about 40% in) it was a good read with an interesting mystery. The 'twists' weren't as profound as the first book but they were suspenseful. It seems like a lot of loose ends were left after this one (more than in <i>The Girl with the Dragon Tattoo</i>), so it looks like the third book ties more into this one. I'll probably have to read it at some point.
