Just finished
The Girl with the Dragon Tattoo. I liked it. Some parts were over-the-top dark, but nonetheless I liked the story and characters. There were some heavy exposition passages on the front third that could have been shortened, but the book really picks up two thirds in.
On a related note, this was the first book I read on my nook. Overall, I loved it but I have to put some blame on the publishers: the formatting sucks. Huge gaps delineating pages, apparently, but why? Occasional typos. And with these they want a price increase on Amazon's nice $10 or less price point? Give me a break.
And on THAT note, an interesting article on a point I hadn't considered about ebooks/ereaders.

It's happened to me many times where I buy a book because I've seen someone reading it and the cover intrigued me.
