Oh, it is very slow starting, but then BOOM. It takes off. I couldn't put it down after that, but yes, the first chapter was tough to read - very boring!
I also thought the first chapter of "The Girl with the Dragon Tattoo" was incredibly slow. It took me about two days to get through 20 pages. But I wanted to keep going since everyone talks about how good the book is, and I got sucked it. I read both it and "The Girl who Kicked the Hornets' Nest" is just a few days.
So for those who couldn't get into it right away, I'd say give it 50 pages to try and get into it... And hopefully you'll be hooked!
Also adding Edith Wharton's "The House of Mirth" to the list. I tried to read it since it was one of my cousin's favorite books, but it was like pulling teeth to get through it.
